I need to develop one integration scenario in which PR and PO are suppose to send to other party through SAP PI. The other party has given me the WSDL file. Now i need to consume it and push the PR & PO data from my ECC to other party through PI. I am relatively new to PI. I have founf out that this integration can be done through IDOC to SOAP and ABAP Proxy to SOAP. Can anyone guide me step by step that how this integration can be done through ABAP Proxy to SOAP scenario. If you have ABAP Proxy to SOAP and IDOC to SOAP tutorial, it will be very helpful for me. My preference is to do this integration through ABAP Proxy To Soap. Your guidance will be much appreciated.
