We are developing a custom Retail Sore application using ISA 5.0 b2b framework(This is ECC verison of ISA not CRM). Infact we just wanted to use the login module of ISA(R/3 authentication) and place all our custome code behind the login module. We are succesfull to some extent that the authentcation works fine and after the login is success we see all our custom JSP pages.
But the problem is, when we do some activity through RFCs from our custom JSPs, the user id posted in the R/3 is not the user who is authenticated in login page but the communication user id we gave when configuring XCM settings for JCO.
Any Ideas ? Do we have to pass on the user id from ISA login page through the custom pages ?
