Thanks for your reply Eng Swee Yeoh.
In my case current scenario is IDoc to Proxy, depicted as below:
ECC --> PI7.02 --> SAP AII(Auto ID)
Now if I insert PO in between as below:
ECC --> PO-->PI7.02 --> Prox
I suppose scenario should be configured as follows in PO:
ECC(Idoc) --> (Idoc) PO (SOAP on XI3.0) --> (XI) PI(Proxy) --> SAP AII(Auto ID)
Is this a right configuration?
Kindly confirm.
Many Thanks,
Anurag
