I have faced a issue in RMA process through Mobile device in AWM on invoiced sale order which status is shipped and below screen shots is attached for reference.
Reservation Done :-

SO Confirmed :-

Release to warehouse confirmed:-

Wave ID and Load ID created :-

Work is completed on SO:-

Work is closed:-

Bill of lading ID is created and shipment status is loaded:-

Shipment is confirmed :


Quality Order is passed:-

SO is Invoiced :-

After completion of these all steps successfully, I have created create RMA of above invoiced SO and receive through mobile device and found below error (Return line not found) and unable to complete the process.


My question is:
- AX 2012 (R3) is supported RMA process though mobile portal) ?
- MY PO & RMA AWM all settings are same but PO is successfully processed through mobile device but RMA not, is there any change is required in setups?
- how to fix the above RMA error (Return line not found)
- Any solution or guidelines are available of RMA through mobile device in AX 2012 ?
