Creating inbound delivery without reference to PO - from inbound idoc
I have a scenario wherein I need to create inbound delivery from inbound Idoc from external system without reference of PO. There is no PO created in SAP and this inbound delivery will be used just to receive material (purely for logistic purpose).
I have identified DELVRY03 or 05 as Idoc type but I am not sure whether system will create inbound delivery without having reference PO. I have two questions here -
1. Can we create inbound delivery without reference to PO?
2. If yes, which Idoc type should I use to create such inbound delivery?
