Another of the many MRP settings within SAP is the Planning Mode setting. The option reactivates unfirmed procurement proposals and, if necessary, adapts the quantity and date to the new planning situation. The BOM is re-exploded only for procurement proposals that are to be adapted. It will reactivate unfirmed procurement proposals and, if necessary, adapts the quantity and date to the new planning situation. The BOM is always re-exploded; and regenerates unfirmed procurement proposals completely. (this description is from F1 help in transaction MD02 for the field)
This setting offers you three different options for the planning run. The first is Adapt Planning Data which is used for most normal executions for only considering updates to planned orders if there were changes to the planning situation for the material. The third setting is the Delete and Recreate
Planning Data, which does exactly what it means; deletes and recreates the planned orders that have been marked for re-planning. Now the second is Re-explode BOM and Routing which is a feature not fully appreciated. This is the topic that I want to quickly explain a little further.
So what exactly does the re-explosion of the BOM and routing mean? Pretty much what it says, but the important part is also included. Whenre-exploding the routing, and assuming you are running with lead timescheduling and capacity requirements, this will mean that any updates to workcenters for scheduling available capacity will now be included in the planning run. The benefit of this option is that it will pick up your updates and reallocate the capacity as required. Additionally, the work will be scheduled across the work center according to the new scheduling parameters.
This is very beneficial for your capacity planners to know that the MRP planning run will begin picking up capacity and scheduling updates each time the planning run is executed.
