Execute Work Item: Invalid Link (SWN155) for WD ABAP task ?

Dear all,

I have created a workflow task with WEBSERVICE object and configured task visualization with WD ABAP application.

When i am executing the work item through  SAP Inbox , the application is triggering successfully.

But when the work item is transmitted to Outlook through Extended notifications configuration i am getting the error

Execute Work Item: Invalid Link (SWN155).

We have already implemented the 1381164 and 1164090 OSS notes.

We don't have UWL, the link need to be opened the WD application directly.

I am unable to find the error.

Please help to solve the issue.

Thanks,
Vamshi
