You can use this heuristic to merge planned orders you have selected in the DS planning board .
The system increases the order quantity of an existing order to the sum of all selected individual orders and deletes the other selected orders. All of the pegging relationships are transferred to the merged order.
This heuristic uses the function module /SAPAPO/HEUR_MERGE_ORDERS.
Before orders can be merged, the following prerequisites must be met:
All orders must reference the same production process model
All orders must be planned orders
All orders must be synchronized, that is, the start and end times of the orders must be the same.
All orders must be scheduled at a multi resource with storage characteristics
Synchronization must be activated in the master data of the resource
