This planning function calculates changes made to components and routings lines, and it involves items on lower production BOM levels, for which it may generate new production orders.
Based on the changes you have made to the components and routing lines, the Replan function calculates and plans for any new demand for the production order. It is typically used after you have added or changed components that constitute underlying production orders.
Note: To include changes made to the header, you must first refresh (See Refresh a Production Order).
From a production order, click Line, Components.
Add a component, which is a produced item (a subassembly).
From the production order, click Functions, Replan.
In the Replan Production Order window, on the Options tab, define how and what to replan:
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 earliest 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.
In the Plan field, select whether to calculate production requirements for produced items on the production BOM:
No Levels – to not consider lower level production. This only updates the item’s schedule (like refresh).
One Level – to plan for 1.-level production demand. 1.-level production orders may be created).
All Levels – to plan for all-level production demand. All-level production orders may be created.
Select One Level, and click OK to replan the production order plus calculate and create a new underlying production order for the introduced subassembly – if it is not fully available.
Note: Changes implemented with the Replan 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.)
