Hi,
It depends on your requirement like from which SLoc you want the picking to be carried out. Whether the material will be always in packed form ? or do you want to pick the materials in a non - HU managed Sloc and perform packing as a separate step in delivery.
Whether it is applicable for only certain materials / customers ?
Based on the above you can define rules for your SLoc determination such as MALA/RETA etc. and accordingly the Sloc will be determined for picking in the delivery.
Thanks n Regards,
