Hi,
I would think this should work when searching in the bulk storage type area first with no partial pallet allowed and have the other storage type next in the sequence? But maybe it helps to have a
strategy "Stock Removal Suggestion According to Quantity " set up (see here http://help.sap.com/saphelp_ewm900/helpdata/en/0f/c49341ec74ac5fe10000000a1550b0/frameset.htm)
Best regards
Juergen
