Restrict workitems tasks to not to be able to forward in UWL

Hi Friends,

We are using SAP Netweaver 7.31 Portal and we have 33 workitems in our customized UWL in which we do not want some tasks to be forwarded to some group of users. When any user tries to forward any workitem to the users in that group, he/she should get a pop up with error message that these workitems cannot be forwarded.

This functionality is already applicable in the backend system from which UWL is fetching data.

Help me by finding a way to implement this in UWL

Regards,

Sindhu
