User validation for creating new business document in synchronous scenario
I am working in 2 synchronous dependent scenario between .Net application (SOAP) <--> SAP-PI <--> ABAP Inbound proxies.
Scenario 1 : User Validation
<Description> User exists and has necessary authorization to create quotation<Description>
Scenario 2 : Create Quotation
Now the million dollar question, how in scenario 2 I can catch the user of the scenario 1 as per the requirement the same user Rebecca should be used in scenario to create the quotation in SAP-ECC.
1. Should I add 1 more field in the sender .Net application to send the user name when they are sending the request to create quotation.
2. This part I want to know whether it can be possible in SAP-ECC and SAP-PI i.e. how to correlate the scenario 1 and scenario 2 with the user id.
