+==================================
+Use the Master Production Schedule
+==================================
+
+The Master Production Schedule (MPS) is a valuable tool to plan your
+production based on your demand forecast.
+
+Configuration
+=============
+
+Go to the *Manufacturing app > Configuration > Settings* and activate
+the Master Production Schedule feature before hitting save.
+

+
+.. tip::
+        In the manufacturing settings, you can define the time range of your MPS (month/week/day) and the number of periods you want to display.
+
+Now, go in *Planning > Master Production Schedule* and click on add a
+product. You can now define your safety stock target (= the stock you
+want to have on hand at the end of the period) and the minimum and
+maximum quantities to replenish.
+
+.. image:: media/use_mps_02.png
+    :align: center
+
+.. tip::
+        The products are ordered in the MPS based on their sequence. You can
+        rearrange that sequence by going on the list of your products and
+        reorganize them with drag and drop.
+

+
+In the MPS view, you can decide which information you would like to show
+by clicking on *rows*. Some fields can be added to the view, such as
+*Actual demand*, which will show which quantity of products has
+already been ordered for the period, or *Available to Promise*, which
+allows you to know what can still be sold during the period (what you
+plan to replenish - what is already sold during the period). You can
+also decide to hide some information if it isn’t necessary.

+
+Estimate your demand and launch replenishment
+=============================================
+
+The next step is to estimate the demand for the period. This estimation
+should be entered in the row *Demand Forecast*. You can easily, at any
+time, compare the demand forecast with the actual demand (= confirmed
+sales). The demand forecast for a finished product will impact the
+indirect demand for its components.
+
+.. image:: media/use_mps_05.png
+    :align: center
+
+Then, the quantity to replenish for the different periods will be
+automatically computed. The replenishments you are supposed to launch
+based on your lead times (vendor lead time or manufacturing lead time)
+are displayed in green. You can now launch the replenishment by clicking
+on the replenish button.
+
+Depending on the configuration of the product (buy vs. manufacture),
+requests for quotations or manufacturing orders will be created. You can
+easily access those by clicking on the *Actual Replenishment* cell.

+
+In case you manually edit the *To replenish* quantity, a small cross
+will appear on the left. In case you want to go back to the
+automatically computed value given by Odoo, you can click the cross.

+
+Cells color signification
+=========================
+
+The cells, which are part of the *To replenish* line, can take
+different colors depending on the situation:
+
+-  **Green**: quantity of products which should be replenished to
+       reach the expected safety stock considering the demand forecast
+       and the indirect demand forecast.
+
+-  **Grey**: replenishment order has already been generated, and its
+       quantity still matches current data.
+
+-  **Red**: replenishment order has already been generated, and its
+       quantity was too high considering current data.
+
+-  **Orange**: replenishment order has already been generated, and
+       its quantity was too low considering current data.
+
+The *Forecasted stock* line can also contain red cells, which means
+the stock will be negative during the period in question.
+
+What if I have underestimated the demand?
+-----------------------------------------
+
+You can still increase the demand forecast. It will impact the quantity
+to replenish. The cell will become orange, and you’ll be able to launch
+a new replenishment.
+
+What if I have overestimated the demand?
+----------------------------------------
+
+You can decrease the demand forecast. The cell will become red to inform
+you that you’ve ordered more than planned. If you’re still able to do
+it, you can cancel some RFQ or MO manually.
+
+What if I wrongly added a product to the MPS?
+---------------------------------------------
+
+You can easily remove a product from the MPS by clicking the small bin
+on the right of its name.
