Hi Amith,

As you said it was working wel before so System Alias must be correct.

So,

Definitely this is SSO certificate issue(either wrong/expired SSO certificates are there currently).

Ask your basis team to reimport SSO certificates. It will resolve the same..

Thanks,

Amey

Please let us know step by step procedure to resolve this issue.

It is very urgent.

Hi,

Login to Strustsso2 of the backend system and see if the portal cert is not expired. Check that you have the certs in both cert list and ACL.

Try to check the port between the portal and the backend if some network issue.

Thanks

From the same backend system we are able to access all the iviews that are created using Webdypro java .

When users created any request using iViews it is created.But that Task is not displayed in UWL --it will display above error.

SSO working fine for all the application that are using same front end and backend system.Except UWL it is not working.

[junwu]

the message is quite clear, right?

[amith808403]

Hi Rishi,

Both the certificates are valid and SSO is Working Fine.

Please check the config where the user BPCTEST is used as mentioned by Jun as per the below message.

Cannot find user "BPCTEST" for request type Delta.

Thanks

Hi,

Have you Define the SAP ECC system and Alias in the portal system landscape. Try to do connection test in system landscape.

Does the user with which you are trying have proper access in the backend.(Check he is not locked in the backend or doenot have valid date.)

As mentioned earlier check SSO.

If the portal and the backend are on different system check that the post is open and you can use telnet command to connect the backend.

Thanks
