+=====
+
+Introduction
+============
+
+The Chilean localization has been improved and extended in Odoo v13. In this version, the next 
+modules are available:
+
+- **l10n_cl:** Adds accounting features for the Chilean localization, which represent the minimal 
+  configuration required for a company to operate in Chile and under the SII 
+  (Servicio de Impuestos Internos) regulations and guidelines.
+  
+- **l10n_cl_edi:** Includes all technical and functional requirements to generate and receive 
+  Electronic Invoice via web service, based on the SII regulations. 
+
+- **l10n_cl_reports:** Adds the reports Propuesta F29 y  Balance Tributario (8 columnas). 
+
+Configuration
+=============
+
+Install the Chilean localization modules
+----------------------------------------
+
+For this, go to *Apps* and search for Chile. Then click *Install* in the module **Chile 
+E-invoicing**. This module has a dependency with **Chile - Accounting**. In case this last
+one is not installed, Odoo installs it automatically with E-invoicing.
+
+.. image:: media/Chile01.png
+   :align: center
+   :alt: Chilean module to install on Odoo.
+
+.. note::
+   When you install a database from scratch selecting Chile as country, Odoo will automatically
+   install the base module: Chile - Accounting.
+   
+   
+Company Settings
+----------------
+
+Once the modules are installed, the first step is to set up your company data. Additional
+to the basic information, you need to add all the data and elements required for Electronic 
+Invoice, the easiest way to configure it is in 
+:menuselection:`Accounting --> Settings --> Chilean Localization`.
+
+Fiscal Information
+~~~~~~~~~~~~~~~~~~
+
+Fill in the fiscal information for your company according to the SII register, follow the
+instructions on each section.
+
+.. image:: media/Chile02.png
+   :align: center
+   :alt: Chilean company fiscal data.
+   
+Electronic Invoice Data
+~~~~~~~~~~~~~~~~~~~~~~~
+
+This is part of the main information required to generate electronic Invoice, select your
+environment and the legal information, as well as the email address to receive invoices
+from your vendors and the alias you use to send invoices to your customers.
+
+.. image:: media/Chile03.png
+   :align: center
+   :alt: Chilean edi environment settings.
+
+Configure DTE Incoming email server
+***********************************
+
+In order to receive you the claim and acceptance emails from your customers, it is
+crucial to define the DTE incoming email server, considering this configuration: 
+
+.. image:: media/Chile03_2.png
+   :align: center
+   :alt: Incoming email server configuration for Chilean DTE.
+
+.. tip::
+   For your Go-live make sure you archive/remove from your inbox all the emails
+   related to vendor bills that are not required to be processed in Odoo. 
+   
+Certificate
+~~~~~~~~~~~
+
+In order to generate the electronic invoice signature, a digital certificate with the extension ``.pfx``
+is required, proceed to this section and load your file and password. 
+
+.. image:: media/Chile03_3.png
+   :align: center
+   :alt: Digital certificate access.
+
+.. image:: media/Chile04.png
+   :align: center
+   :alt: Digital certificate configuration.   
+
+A certificate can be shared between several users. If this is the case leave the user field empty,
+so all your billing users can use the same one. On the other hand,  if you need to restrict the
+certificate for a particular user, just define the users in the certificate. 
+
+Financial Reports
+~~~~~~~~~~~~~~~~~
+
+The report Propuesta F29 requires two values that need to be defined as part of the company
+configuration: 
+
+.. image:: media/Chile05.png
+   :align: center
+   :alt: Fiscal reports parameters.
+
+Multicurrency
+~~~~~~~~~~~~~
+
+The official currency rate in Chile is provided by the SBIF, you can find the SBIF
+synchronization service in the currency rate configuration and you can set a predefined interval
+for the rate updates.  
+
+.. image:: media/Chile05_2.png
+   :align: center
+   :scale: 25
+   :alt: Currency reate service for Chile.
+
+In order to configure your token, you need to enable developer mode and access to
+:menuselection:`Settings --> Technical --> System parameters` and search the parameter
+``sbif_api_key`` and in the field Value introduce your token provided by the SBIF:
+
+.. image:: media/Chile05_3.png
+   :align: center
+   :alt: Token configuration for currency rate service.
+   
+Chart of accounts
+~~~~~~~~~~~~~~~~~
+
+The chart of accounts is installed by default as part of the set of data included in
+the localization module. The accounts are mapped automatically in: 
+
+- Taxes.
+- Default Account Payable.
+- Default Account Receivable.
+- Transfer Accounts.
+- Conversion Rate.
+
+
+Master Data
+-----------
+
+Partner
+~~~~~~~
+
+Identification Type and VAT
+***************************
+
+As part of the Chilean localization, the identification types defined by the SII
+are now available on the Partner form. This information is essential for most transactions.
+
+.. image:: media/Chile06.png
+   :align: center
+   :scale: 25
+   :alt: Chilean identification types for partners.
+ 
+TaxpayerType
+************
+
+In Chile, the document type associated with customers and vendors transactions is defined
+based on the Taxpayer Type. This field should be defined in the partner form, when creating
+a customer is important you make sure this value is set:
+
+.. image:: media/Chile07.png
+   :align: center
+   :alt: Chilean taxpayer types for partners.   
+ 
+
+Electronic Invoice Data
+***********************
+
+As part of the information that is sent in the electronic Invoice, you need to define the
+email that is going to appear as the sender of the electronic invoice to your customer, and
+the Industry description. 
+
+.. image:: media/Chile07_2.png
+   :align: center
+   :alt: Chilean electronic invoice data for partners.
+   
+
+Taxes
+~~~~~
+
+As part of the localization module, the taxes are created automatically with their related
+financial account and configuration.
+
+.. image:: media/Chile08.png
+   :align: center
+   :alt: Chilean taxes list.
+
+Taxes Types
+***********
+
+Chile has several tax types, the most common ones are:
+
+- VAT. Is the regular VAT and it can have several rates. 
+- ILA (Impuesto a la Ley de Alcholes). Taxes for alcoholic drinks. It has a different rate.
+
+
+Fiscal Positions
+~~~~~~~~~~~~~~~~
+
+Based on the purchase transactions, the VAT can have different affections. This will be done
+in Odoo using the default purchase fiscal positions. 
+
+
+Document Types
+~~~~~~~~~~~~~~
+
+In some Latin American countries, including Chile, some accounting transactions like invoices and
+vendor bills are classified by document types defined by the government fiscal authorities (In
+Chile case: SII).
+
+The document type is essential information that needs to be displayed in the printed reports and
+that needs to be easily identified within the set of invoices as well of account moves.
+
+Each document type can have a unique sequence per journal where it is assigned. As part of the
+localization, the Document Type includes the country on which the document is applicable and the data
+is created automatically when the localization module is installed.
+
+The information required for the document types is included by default so the user doesn't need to
+fill anything on this view:
+
+.. image:: media/Chile09.png
+   :align: center
+   :alt: Chilean fiscal document types list. 
+
+.. note::
+   There are several document types that are inactive by default but can be activated if needed.
+
+
+Use on Invoices
+***************
+
+The document type on each transaction will be determined by:
+
+- The Journal related to the Invoice, identifying if the journal uses documents.
+- Condition applied based on the type of Issues and Receiver (ex. Type of fiscal
+  regimen of the buyer and type of fiscal regimen of the vendor).
+  
+
+Journals
+--------
+
+Usage
+~~~~~
+
+Sales
+*****
+
+Sales Journals in Odoo usually represent a business unit or location, example:
+
+- Ventas Santiago.
+- Ventas Valparaiso.
+
+For the retail stores is common to have one journal per POS: 
+
+- Cashier 1.
+- Cashier 2.
+
+
+Purchases
+*********
+
+The transactions purchase can be managed with a single journal, but sometimes companies use
+more than one in order to handle some accounting transactions that are not related to vendor
+bills but can be easily registered using this model, for example:
+
+- Tax Payments to government.
+- Employees payments.
+
+
+Configuration
+~~~~~~~~~~~~~
+
+When creating sales journals the next information must be filled in: 
+
+**Point of sale type**: If the Sales journal will be used for electronic documents, the option
+Online must be selected. Otherwise, if the journal is used for invoices imported from a previous
+system or if you are using the SII portal “Facturación MiPyme“ you can use the option Manual. 
+
+**Use Documents**: This field is used to define if the journal will use Document Types. It is only
+applicable to Purchase and Sales journals that can be related to the
+different sets of document types available in Chile. By default, all the sales journals created will
+use documents. 
+  
+.. image:: media/Chile10.png
+   :align: center
+   :alt: Document type configuration on Journal.
+
+Sequences
+*********
+
+When a Journal is created we have two options with document types sequences. 
+
+1. Create new sequences: In this case, Odoo will create new sequences for the most common document
+   types. 
+2. Use existent sequence: If the sequence should be shared between several journals, the user can
+   add manually sequences previously created.  
+
+.. image:: media/Chile11.png
+   :align: center
+   :alt: Steps to add new sequences on journals.
+   
+.. important::
+   For the Chilean localization it’s important to define the default Debt and Credit accounts 
+   as they are required for one of the debit notes use cases.
+   
+CAF
+***
+
+For each sequence related to the documents type, a CAF (Folio Authorization Code) is required,
+the CAF is a file the SII provides to the Emisor with the folio/sequence authorized for the 
+electronic invoice documents.
+
+Your company can make several requests for folios and obtain several CAFs, each one associated
+with different ranges of folios. In this way, you could order folios per the different
+segmentations you have in your journals (example per office) thus avoiding distributing a range
+of folios. In this way, each branch would have its private key of the respective CAF.
+
+Please refer to the SII documentation to check the detail on how to acquire the CAF:
+`SII Timbraje <https://palena.sii.cl/dte/mn_timbraje.html>`_.
+
+	
+Configuration
+^^^^^^^^^^^^^
+
+Once you have the CAF files you need to associate them with journal sequence in Odoo,
+after you create the sequence for the first time the will be in red, which indicates
+that no CAF has been configured for that particular sequence:
+
+.. image:: media/Chile12.png
+   :align: center
+   :alt: Sequences per document type on journals.
+
+In order to add a CAF, just follow these steps:
+
+1. Open the sequence. 
+2. Go the the Tab “CAF”.
+3. Upload the file.
+4. Save the CAF.
+5. Save the sequence. 
+
+.. image:: media/Chile13.gif
+   :align: center
+   :alt: Steps to add a new CAF on sequences.
+
+
+As a result, the sequence color changes to black and the column Next number and quantity
+available are updated:

+   :alt: Sequences per document type on journals.   
+
+
+Usage and Testing
+=================
+
+Electronic Invoice Workflow
+---------------------------
+
+In the Chilean localization the electronic Invoice workflow covers the Emission of
+Customer Invoices and the reception of Vendor Bills, in the next diagram we explain how
+the information transmitted to the SII and between the customers and Vendors. 
+
+.. image:: media/Chile14.png
+   :align: center
+   :alt: Diagram with Electronic invoice transactions.
+   
+
+Customer invoice Emission
+-------------------------
+
+After the partners and journals are created and configured, the invoices are created in
+the standard way, for Chile one of the differentiators is the document type which is selected
+automatically based on the Taxpayer. 
+
+You can manually change the document type if needed. 
+
+.. image:: media/Chile15.png
+   :align: center
+   :alt: Document type selection on invoices.
+
+
+Validation and DTE Status
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+When all the invoice information is filled, either manually or automatically when it’s created
+from a sales order, proceed to validate the invoice.  After the invoice is posted:
+
+- The DTE File (Electronic Tax Document) is created automatically and added in the chatter.
+- The DTE SII status is set as: Pending to be sent. 
+
+  .. image:: media/Chile16.png
+     :align: center
+	 :alt: DTE XML File displayed in chatter.
+
+The DTE Status is updated automatically by Odoo with a scheduled action that runs every day
+at night, if you need to get the response from the SII immediately you can do it manually as well.
+The DTE status workflow is as follows: 
+
+.. image:: media/Chile17.png
+   :align: center
+   :alt: Transition of DTE statuses.
+   
+
+1. In the first step the DTE is sent to the SII, you can manually send it using the button: Enviar
+   Ahora, a SII Tack number is generated and assigned to the invoice, you can use this number to 
+   check the details the SII sent back by email. The DTE status is updated to Ask for Status.
+
+
+2. Once the SII response is received Odoo updates the DTE Status, in case you want to do it 
+   manually just click on the button: Verify on SII. The result can either be Accepted, Accepted 
+   With Objection or Rejected.
+   
+   .. image:: media/Chile18.png
+      :align: center
+	  :alt: Identification transaction for invoice and Status update.
+
+
+   There are several internal status in the SII before you get Acceptance or Rejection, in
+   case you click continuously  the Button Verify in SII, you will receive in the chatter the
+   detail of those intermediate statuses:
+   
+   .. image:: media/Chile18_2.png
+      :align: center
+	  :alt: Descprtion of each DTE status in the chatter.
+
+3. The final response from the SII, can take on of these values:
+
+
+   **Accepted:** Indicates the invoice information is correct, our document is now fiscally valid
+   and it’s automatically sent to the customer. 
+
+   **Accepted with objections:** Indicates the invoice information is correct but a minor issue
+   was identified, nevertheless our document is now fiscally valid and it’s automatically
+   sent to the customer.
+
+   .. image:: media/Chile19.png
+      :align: center
+	  :alt: Email track once it is sent to the customer.
+
+   **Rejected:** Indicates the information in the invoice is incorrect and needs to be
+   corrected, the detail of the issue is received in the emails you registered in the
+   SII, if it is properly configured in Odoo, the details are also retrieved
+   in the chatter once the email server is processed.
+	 
+   If the invoice is Rejected please follow this steps:
+	 
+   * Change the document to draft.
+   * Make the required corrections based on the message received from the SII.
+   * Post the invoice again.
+	 
+   .. image:: media/Chile20.png
+      :align: center
+	  :alt: Message when an invoice is rejected.
+
+
+Crossed references
+~~~~~~~~~~~~~~~~~~
+
+When the Invoice is created as a result of another fiscal document, the information related to the
+originator document must be registered in the Tab Cross Reference, which is commonly used for 
+credit or debit notes, but in some cases can be used on Customer Invoices as well. In the case of the
+credit and debit notes, they are set automatically by Odoo:
+
+.. image:: media/Chile21.png
+   :align: center
+   :alt: Invoice tab with origin document number and data.
+
+Invoice PDF Report
+~~~~~~~~~~~~~~~~~~
+
+After the invoice is Accepted and valdiated by the SII and the PDF is printed it includes the
+fiscal elements that indicates out document is fiscally valid:
+
+.. image:: media/Chile22.png
+   :align: center
+   :alt: Barcode and fiscal elements in the invice report.
+
+
+Commercial Validation
+~~~~~~~~~~~~~~~~~~~~~
+
+Once the invoice has been sent to the customer:
+
+1. DTE partner status changes to “Sent”.
+2. The customer must send a reception confirmation email.
+3. Subsequently, if all the commercial terms and invoice data are correct, they will send the
+   Acceptance confirmation, otherwise they send a Claim.
+4. The field DTE acceptation status is updated automatically. 
+
+.. image:: media/Chile23.png
+   :align: center
+   :alt: Message with the commercial acceptance from the customer.
+   
+
+Processed for Claimed invoices
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Once the invoice has been Accepted by the SII **it can not be cancelled in Odoo**.  In case you
+get a Claim for your customer the correct way to proceed is with a Credit Note to either cancel
+the Invoice or correct it. Please refer to the Credit Notes section for more details. 
+
+.. image:: media/Chile24.png
+   :align: center
+   :alt: Invoice Comercial status updated to Claimed.
+
+Common Errors
+~~~~~~~~~~~~~
+
+There are multiple reasons behind a rejection from the SII, but these are some of the common errors
+you might have and which is the related solution. 
+
+- Error: RECHAZO- DTE Sin Comuna Origen.
+  
+  *Hint:* Make sure the Company Address is properly filled including the State and City. 
+
+- Error en Monto :  - IVA debe declararse.
+  
+  *Hint:* The invoice lines should include one VAT tax, make sure you add one on each invoice line. 
+
+- Error: Rut No Autorizado a Firmar.
+  
+  *Hint:* The invoice lines should include one VAT tax, make sure you add one on each invoice line. 
+
+- Error: Fecha/Número Resolucion Invalido RECHAZO- CAF Vencido : (Firma_DTE[AAAA-MM-DD] - 
+  CAF[AAAA-MM-DD]) &gt; 6 meses.
+  
+  *Hint:* Try to add a new CAF in the journal sequence related to this document as the one you’re 
+  using is expired. 
+
+
+
+Credit Notes
+------------
+
+When a cancellation or correction is needed over a validated invoice, a credit note must be
+generated. It is important to consider that a CAF file is required for the Credit Note sequence,
+which is identified as document 64 in the SII.  
+
+.. image:: media/Chile25.png
+   :align: center
+   :alt: Creation of CAF for Credit notes sequences.
+
+
+.. tip:: Refer to the journal section where we described the process to load the CAF on each 
+   sequence.
+
+Use Cases
+~~~~~~~~~
+
+Cancel Referenced document
+**************************
+
+In case you need  to cancel or invalid an Invoice, use the button Add Credit note and select Full
+Refund, in this case the SII reference Code is automatically set to: Anula Documento de referencia.

+   
+Odoo creates a Credit Note with the corrected text in an invoice and price 0.
+
+.. image:: media/Chile28.png
+   :align: center
+   :alt: Credit note with the corrected value on the invoice lines.
+
+.. important::
+   It’s important to define the default credit account in the Sales journal as it
+   is taken for this use case in specific. 
+
+Corrects Referenced Document Amount
+***********************************
+
+When a correction on the amounts is required, use the button Add Credit note
+and select Partial Refund. In this case the SII reference Code is automatically
+set to: Corrige el monto del Documento de Referencia.
+

+
+Debit Notes
+-----------
+
+As part of the Chilean localization, besides creating credit notes from an existing document you
+can also create debit Notes. For this just use the button “Add Debit Note”.  The two main use
+cases for debit notes are detailed below. 
+
+Use Cases
+~~~~~~~~~
+
+Add debt on Invoices
+********************
+
+The most common use case for debit notes is to increase the value of an existing invoice, you
+need to select option 3 in the field Reference code SII:
+
+.. image:: media/Chile31.png
+   :align: center
+   :alt: Debit note for partial refund to crrect amounts, using the SII reference code 3.
+   
+   
+In this case Odoo automatically includes the source invoice in the cross reference section:

+.. image:: media/Chile32.png
+   :align: center
+   :alt: Invoice data on crossed reference section for debit notes.
+
+Cancel Credit Notes
+*******************
+
+In Chile the debits notes are used to cancel a validated Credit Note, in this case just
+select the button Add debit note and select the first option in the wizard: *1: Anula 
+Documentos de referencia.*
+
+.. image:: media/Chile33.png
+   :align: center
+   :alt: Creating a debit note to cancel a credit note with the SII code reference 1.
+
+
+Vendor Bills
+------------
+
+As part of the Chilean localization, you can configure your Incoming email server as the same you
+have register in the SII in order to:
+
+- Automatically receive the vendor bills DTE and create the vendor bill based on this information. 
+- Automatically Send the reception acknowledgement to your vendor. 
+- Accept or Claim the document and send this status to your vendor. 
+
+
+Reception
+~~~~~~~~~
+
+As soon as the vendor email with the attached DTE is received:
+1. The vendor Bill mapping all the information included in the xml.
+2. An email is sent to the vendor with the Reception acknowledgement. 
+3. The DTE status is set as:  Acuse de Recibido Enviado
+
