I have a storage unit at a 3PL storage location, and I need to transfer it via 2-step STO to the main plant storage location. Both SLOCs are SU-managed and assigned to same warehouse. The SU could be a full pallet or partial pallet pick. My requirement is for the 3PL to do any new SU label generation and affixing to item, so that receivers in the main plant don't have to do that task. I've tried a couple things and have hit dead ends:
1) Can't make 921 Transfer interim storage type SU managed as negative stock needs to be allowed
2) Preplanning with pick ID point -- Problem here is that my picked quantity would be the one put back in storage. I need it other way around...picked quantity remains in some temp storage type with new SU. Plus, same #1 issue remains
Only other option I can think of is for 3PL to complete the GR step of STO so new SU gets generated. The SU would have to go to a temp storage type (using special movement indicator?), for the main plant Receiver to put away into final destination. I should add that in this scenario, I might as well not have the 3PL be on WM to simplify their SAP process.
Is this the best approach? Am I missing any other options? (I thought about 2-step confirmation, but the destination in main plant should only be dynamically determined upon physical receipt.)
Thanks, Vlad
