Is there a way to double check the setup required for an item to go trough receipt routing?

We have implemented receipt routing for items to go through at the time of a ship confirmation (p4205) for a ST. We set up P4205 processing option #10 under the process tab with '1' and informed P4312 version to activate receipt routing behind the versions tab.

We set up both P43090 and P43091, just basic setup.

Usually, the Orders go through receipt routing, but we have cases where this doesn't work.

Can somebody tell me what else can we assess to have 100% of our transfers orders working properly on receipt routing ?

Kind regards
