Using 4.7 and APO 4.0. We're having to create multiple schedule lines (EKET) for PO Items for TP/VS functionallity. I've found a neat trick for doing this by using BADI ME_PURCHDOC_POSTED to trigger an FM in a new task.
This FM waits until PO is unlocked and then uses BADI_PO_CHANGE to "split" the schedule lines. However I'm having trouble finding an easy way to populate new customer (Z) fields on the Schedule Line at the same time.
