BPM move inventory when primary bin is changed

Primarily when Im trying to check the Bin a part is in. For some reason it’s throwing a fit about PCID. When I manually transfer a part & quantity into another bin it works fine and doesnt require PCID. I would very much appreciate an BPM or code to help. I just made a post about my issue here: Inventory Transfer UBAQ-Custom Code problem "PCID required"
