This planning function calculates changes made to a production order header and does not involve production BOM levels.
The Refresh function basically calculates and initiates the values of the component lines and routing lines based on the master data defined in the assigned production BOM and routing and according to the order quantity and due date on the production order’s header. It is typically used after you have:
created a production order header manually – to calculate and create line data for the first time.
made changes to the production order header – to recalculate all the line data.
Note: You can change component lines and routing lines “on the fly” and the production order schedule is updated accordingly. When you refresh, those changes are cancelled as the order is reset according to master data.
Create a new production order header or change the Quantity or Due Date fields on an existing one.
Click Functions, Refresh.
In the Refresh Production Order window, on the Options tab, define how and what to refresh:
In the Scheduling Direction field, select:
Back – to calculate the operation sequence backwards from the earliest possible ending date (defined by due date and/or other scheduled orders) to the latest possible starting date.
Note: This default option is relevant in the majority of situations.
Forward – to calculate the operation sequence forward from the latest possible starting date (defined by due date and/or other scheduled orders) to the earliest possible ending date.
Note: This option is relevant for ASAP orders.
Select in the Calculate field which parts of the production order to calculate when refreshing.
Place a check mark in the Warehouse – Create Inbound Request field, to create a warehouse request for the putting away of the production order's components.
Note: The warehouse location must be set up to require put-away processing but not directed put-away and pick.
Click OK to start the Refresh function according to your settings.
Note: It is not allowed to refresh a reserved production order. You can restore the reservation after the production order is refreshed, but in that case you should cancel the reservation before you refresh.
Note: Changes implemented with the Refresh function are very likely to change the capacity need of the production order and you may therefore have to reschedule operations afterwards. (See Reschedule an Operation.)
