SSO not working for custom SAP Webdynpro ABAP applications that runs in the SAP Portal.
I have one SAP Portal issue related to SSO. Issue details are provided below and hope, somebody can help me to resolve the issue.
We have a SAP Portal system (Java stack, NW04s) that has iViews of type Webdynpro ABAP. The custom Webdynpro ABAP applications reside on another system (ABAP stack, running ECC6). We have configured the trust relationship between SAP Portal and SAP ECC system. However, for the custom WebDynpro ABAP applications, when calling it for the first time, a logon screen shows up.
How can we get rid of it? What are we missing to have SSO work for the custom WebDynpro ABAP applications?
Any ideas or suggestions! Thanks in advance.
