We are developing EDI 850 scenario.
Flow is EDI Customer ---> Thirdparty --> PI --> ECC
Thirdparty will get EDI data and converts in to file/xml (not yet decided) to PI, From PI Idoc will go to ECC.
Now the question is client is expecting 997 functional acknowledgement. Third party will send that, before that PI needs to send confirmation that Idoc got created and success in ECC. How to handle this in PI, Where we need to implement this with in the same interface.
