UWL on EP6 SP2.

Hi,

we are on EP6 SP2 Patch level 8, trying to configure Universal worklist. I was able to complete the configuration as per SAP guide without errors, and now got the following error:

- when there inbox is empty, UWL works allright and displays empty folder. But as soon as ANY workitem/request/note is created in the inbox, the UWL will stop working and display the error message "Unable to perform the request. Please try again. If the problem persist, please inform your system administrator".

if i'll go to SAPgui inbox and delete the items, the UWL would resume and display empty inbox.

Does anyone know what might cause the issue? it's very urgent.

Thank you very much for your responses,

Serge
