Wadaco - ATTACH_RECEIPT_TO_HANDLING_UNIT for RMA source

Hi!

I can’t force ATTACH_RECEIPT_TO_HANDLING_UNIT process to work properly for RMA source. This is what I’m doing step by step assuming that RMA for Customer Order is registered and released and proper empty Handling Unit exists.

1. Using in Cloud:  Register Arrival screen / Receive Parts against Order Deliveries option:

I register 3 pcs of KM20240427 part to location RAMPA - arrival type:

2.  Using ATTACH_RECEIPT_TO_HANDLING_UNIT  Wadaco process with almost no changes to standard configuration (just to show SOURCE_REF_TYPE and not use automatic value)

I attach this arrival line to handling unit ID 5079:

I’m getting info that everything is correct:

But it doesn’t seem so…

Here (and in transaction history) it looks OK:

but here it’s not:

Because of that you can’t use e.g. “Move to One Location” option… System wants to move handling unit 0, but this can’t be done because this lot batch is already packed into 5079…

Can anybody help me with this issue? Is it a bug in IFS? Or maybe I’m doing sth wrong...
