I have a requirement using idoc_aae in pi7.4 single stack.There are 2 ECC systems and it is connected to a single PI. Same Idoc is triggered from both ECC . Two scenarios are there in the PI for different ECC using same IDOC with different mapping.
I went through sender Idoc_aae configuration in single stack. But the confusion here is how PI will identify which mapping or scenario it has to take since same IDOC used.
