Hi Tamas
So there are two requirements.
1 ) Pick strategy for determining correct HU based on set ID from delivery for all ODO line items.
2) To be able to pick complete HU selected for outbound delivery.
Requirement 1:-
As picking strategy is determined at WT line item...there is no standard way of achieving this(as per my knowledge). Can be achieved by implementing BADI for stock removal strategy.
Update HU number in any custom/unused field in ODO. In the enhancement for picking strategy, code to select quant from /SCWM/AQUA based on "HUIDENT" with HU number from ODO field. This will ensure all lines are picked from same HU.
Requirement 2:-
As you are picking multiple lines from mixed pallet...there will be as many items in WT. System perspective is partial picking. However all these partial picks can be picked into one picking HU. Means you will have new ship HU.
hope this comes close to your requirement ...if not perfect fit.
Best Regards
Phani
