Issues with S4HANA to TM integration using SAP PO

[btiruveedula]

Hello Friends,

I am working on integration of S4HANA 1709 with SAP TM 1809 using SAP PO.

Using ABAP proxies on S4HANA, data will be send to SAP PO, and further to SAP TM that uses enterprise services.

Here I have a query on how to use the enterprise services on SAP TM.

(a) Using the WSDL URL of the enterprise service in SOAP receiver channel - When tested this way, I am facing the error "HTTP 415 Unsupported Media type" in SAP PO. (ofcourse, tried addressing this using MTB as mentioned in few other threads, but then the successful message is not found in SAP TM).

(b) Using the WSDL URL that generated after creating binding - When tested this way, the message processed successfully in SAP PO, but the message neither found in error log nor in message monitor of SAP TM.

Please help me to know which option (a or b) is the correct way to do integration, and how to overcome the further issue mentioned.

Thanks.

Regards
