I am trying to test order change requests using the backlog sandbox server and I always get this response:
"code" : "TI-TXT-062",
"type" : "ERROR",
"reason" : "customerLineItemNumber 742829 cannot be changed",
"message" : "customerLineItemNumber 742829 is in process by TI and cannot be changed. If you are still having issues, contact TI customer support support.ti.com/csm"
Is this normal behavior for any change request on the sandbox server?
Also, which fields are eligible for a change request (price, quantity, requested delivery date..)?
Can you cancel a backlog order using the order change API?
