RMMRP000: Badi for writing purchase requisition instead of stock transfer when MARD-DISKZ = 2

Hi All,

in MD01 or MDBT with RMMRP000 my client wants to always trigger a purchase Requisition instead of a stock Transfer Reservation when:

1. MARD-DISKZ = 2 (separate replenishment for storage Location) is maintained for a certain storrage location

2. other storage locations are valid and calculated on plant Level

3. other storage Locations have enough stock to cover that separate required replenishment

Requested result is that a purchase requistion for replenishment from another plant is ALWAYS triggered separately for that separate storage location.

As I assume that I have to change SAP's standard functionality herefor, I happily open the global discussion for receiving your tips and hints what BADI I should use and how to do so.

Thanks and greeting from Germany

Henning
