Hello SCN!
There're SAP BW system 7.31 and SAP NW Java 7.3 both installed in the same server but with different SIDs. Java instance used BW system as source for UME. On the Java instance there're some WDJ applications used web-services from BW system. Also in Java portal there're some WDA applications included.
The problem is I got error "401 unauthorized" if I try to use "Logon Ticket" variant of Authentification in destination templates for webservices. Destination templates work only with "User ID/Password" variant. Another problem is system show me logon screen of SAP system when I called WDA application from portal, despite system for BW with auth. type "SAP Logon ticket" have created in portal System landscape. Also the last of three connection tests for this system results with error - something like "Unable to establish connection. Make sure that all connection properties and user assignings are correct" (this is approximate translation since the error message displayed not in English...).
My user is active and has same login in both systems.
regards,
Lev
