SSO not working for a custom WDA application that runs in the Portal

[Former Member]

I have a Portal system (Java stack, NW04s) that has an iView of type webDynpro ABAP. The custom Web Dynpro ABAP application resides on another system (ABAP stack, running ECC6). We have configured the trust relationship between the Portal and the ECC system as per

http://help.sap.com/saphelp_nw04s/helpdata/en/61/42897de269cf44b35f9395978cc9cb/content.htm

We know this is working since we are able to run ESS. However, for the custom WebDynpro ABAP application, 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 application?

Hi,

have you checked your configuration settings according to <a href="http://help.sap.com/saphelp_nw70/helpdata/en/43/e86de5008b4d9ae10000000a155369/frameset.htm">this</a>

Heidi, thanks for the pointer... I will have to check the configuration again. One of the notes says that "The service for the application is generally found under the ICF node /default_host/sap/bc/webdynpro/sap/<application>" and I do not see my application created under that node. So there might be something wrong with the configuration. The other issue I found is that the user ids in the Portal and ABAP are different, so I need to perform user mapping. Between the configuration check and the user mapping I think that the problem should be resolved. Thanks again.
