We are migrating from SAP PI 7.0 to SAP PI7.31 single stack.
in Existing landscape(SAP PI7.0) - sender system ECC is receiving the acknowledgements(ALEAUD) for the idocs sent to PI system where in the port is different i.e. port is receiving back with different Partner Number.
But in SAP PI7.31 single stack, ECC is recieving the acknowledgmenets(ALEAUD) as same as the sender partner number of the idoc sent to PI 7.31 system.
can someone please explain me if it is possible to implement the same functionality as per SAP PI7.0 in SAP PI7.31 single stack as well or is this the Limitation of the product.
