My initial requirement was to show workitems in portal's UWL (Uniserval Work List) and this workitem screen will be developed in webdynpro with multiple options for approver. For this i've created a custom user decision. The workitems are visible in both SAP inbox and UWL. Now, client dont want users to approve or reject from SAP inbox. So, my requirement is to show some error message when user tries to process an item in SAP inbox. Please guide me how to tackle this.
Thanks in Advance,
