UWL error on Netweaver EP6 Stack12

Dear UWL experts

I have a problem with the UWL.

I have installed a Netweaver 04 EP6 Stack 12 – Standard installation through the rapid installer. I have no SAP backend systems connected and all I need to use is the standard task list feature that the UWL offers.

Every time I try to create a simple task I receive the error message that I have listed below. more than one operation signature (for operation 'setAssignees') matches arguments passed

I have not configured any specific settings under the UWL administration. I have just added the standard UWL iview to my workset. Shouldn’t the standard UWL iview work without any further customization?

Thanks in advance

    Hi John,

    Have you read it ?


    Content Management 6.0 is installed, though UWL also works without Content Management. See SAP note 702255 for details.

    Each connected SAP R/3 System has the following requirements:

    · Workplace Plug-In 6.0 is installed

    · Connection to the SAP Internet Transaction Server (ITS)

    Each user is:

    · Known to all connected SAP R/3 Systems as per role requirement (make sure that there is one-to-one mapping between the portal user and the backend user )

    · Authorized for RFC access to function group SWK1 and transaction SWK1

      Hi Neil

      I have not created any migration only a standard portal installation by use of the SAP rapid installer based on stack 12. Afterwards I have upgraded to stack 13 and then 14, but the error has occurred since stack 12. The installation failed by I continued by use of starting SAP inst and select “continue old installation”.

      I have looked a several other dB and no duplicates exist here. I have another problem when setting user rights to KM folders, it keeps resetting each time I activate the save button. I think that duplicate entries can be the root for this problem but I can’t locate the table on where user rights are stored.

      I have tired to stop the SAP application but still I am not allowed to delete the duplicates.

      I’ll create an OSS note to SAP and hope they can provide a solution on how to delete these duplicates.

      Thanks for all your help and guidelines

      Kind regards
