Hi George,
Good day, You have to re-think about the requriment we see here, In SEBA you we should create the bins for which pick pack pass process is working example FP01 till FP10 and once you cross this process from all the activity area then POSC will trigger for packing work centre and please use user-driven in WOCR rule not system driven.
Please use in RFUI it will work fine.
Regards,
Rahull
