hi Albun,
if it is not subcontracting means, it is a external operation. you may be doing one operation outside the plant with external vendor. where you just do the operation externally or issue some goods to operation.
you can enter select the control key is pp02 with external operation and enter values for ext processing and do not tick the subcontracting button, in that case system will generate a pr for external operation with acc assignment F.
what is the reason. when you create a recursive bom and go the gi and gr. same material with different batch number?
regards,
Solomon
