I have a scenario with regards to picking mixed pallets (pallets with more than one quant in it). I have a pallet containing multiple quants. I create a delivery that contains these same materials with matching quantities. Is there a way that SAP can propose the source HU as the destination HU when picking the delivery. Currently no matter what config I maintain (HU picking control at both the storage type level and movement type level, or in Define Control for Automatic Creation of Pick HU's) I either have to create the PickHU in a dialogue session or the system creates a PickHU.
I assume you use the ECC solution; in this case the storage determination/HU takeover is limited by the fact the standard logic is bound the a single item line. I am not aware if a BAdI has been added in you version of platform, so the logic can be enhanced across line items. However, last time I had the issue was in 4.7, which required a small customer enhancement from SAP.
