Dear experts,
I am utterly confused about the different abbreviations when it comes to PI installations. Would you be so kind to explain what the difference is between AE, AAE and AEX?
From my current understanding AE means classic dual stack, AAE would be processing on ICO on a dual stack and AEX would be processing on ICO on a single stack.. is this assumption correct?
Another question is about proxy and idoc senders. As I understand on a dual stack we don't need to configure CCs and sender agreements for them as there is communication between the two integration servers directly. The R3 integration server knows the PI integration server and communicates with it directly.
Now on a single stack we don't have an integration server anymore, meaning that the R3 integration server cannot talk to PI directly. Therefore for proxy we are creating a new destination on R3, pointing to the soap channel of PI. On PI we now need to configure a soap sender adapter using the XI protocol in order to receive the proxy messages. Is this right? Did I missunderstand or miss an important step?
For idoc sender I am not sure how it is working now yet as I have no system to test this on. Could you please from your experience say what the biggest differences are?
