My scenario: SOAP(Sender) - - - -> PI - - - > ECC (SOAP XI).
PI Version: 7.5 (single stack)
Objective: Capture user name from sender application and propagate it to ECC (SOAP XI Receiver) dynamically.
I have checked ASMA, Variable Transport Binding, View Authorization keys and maintained "user name" "password" pair. Also, I have set the dynamic header attribute "TAuthKey" with value as "user name" from sending application.
Issue: When I execute the scenrio, ABAP proxy is getting triggered with ECC service user which was hard coded in "General" tab of receiver channel(soap) instead of using dynamic user name from ASMA authentication pair.
