Error while processing message payload Element 'CategoryCode'
I am trying to integrate SAP ECC with TM. I have transferred the sales order from ECC to TM, but its not triggering order based transportation requirement (OTR) instead giving an error Error while processing message payload Element 'CategoryCode' and all the xml messages are stuck in inbound queue. The screen shot of the issue is as appended herewith. Please advise.
Thanks & Regards,
