TLB - heuristic creates STOs without considering the issue SLoc

Hi,

when I create stock transfer orders using TLB in APO the STOs do not contain the issuing storage location from the product / material master data.

then we have to go to the STO in ECC and update it with the issu SLoc...which is of course not nice.

What should be done to make sure that the STO from TLB contains the issue SLOC?

thanks,

kr,

Pilvi
