According to SAP when inbound deliveries are used and your delivery item category is set up for mvt type 101, these should be received with transaction VL32N. If you use MIGO/MB0A instead, the GR status in the delivery will not be updated. If you then report on open deliveries you’ll notice that nothing is received in the course of time. Amazing. Now if you set up the delivery item category without the movement type your inbound will not even be GR relevant. Just one of these things that’s nice hugely critical to be aware of.
