where the PO should be bill to me but it should not show any inventory change as the ship to address is different.

@shadman Ashrafi if I understand correctly you are paying a bill on someone else's behalf and not receiving the goods. In that case, the PO must have non-inventory items on it. Alternatively, receive the goods but then do an adjustment to destroy anything received. This however will not be ideal as the accounting impact of the reception versus destruction may not match exactly. By far best bet is to use Non-Inventory items.

@shadman Ashrafi Sounds like a Drop Ship scenario? If yes, are you using Drop Ship functionality in NS?
