Async Scenario converted to Sync by PI
we have a problem with a very simple scenario. The scenario is like following:
SOAP --> PI --> FILE. It is an asynchronous scenario. We send SOAP message to the SOAP adapter or directly to the IE. The interesting thing is, the PI system shows the call is SYNCHRONOUS. Actually we defined all the service interfaces as async interfaces. The SOAP Sender Adapter is also configured as EO.
Then we made some tests on the RWB through the Test Messages function.
1. Send test messages directly to the IE. PI says the calls are ASYNC but Application-ACK is required by the Sender. We're totally confused. We didn't want any ACK from the FILE Adapter.
2. Send test messages to the AAE. PI says the calls are SYNC and always tries to send responses back.
3. Send test messages from our C# WS Client to the PI using the URL proposed by the PI (the URL is the same as the step 1). PI says the calls are again SYNC and does the same thing as step 2.
So has anyone any idea, where the problem is?
thanks a lot in advance
