Hi Shakira
All work center home page applications are ABAP WebDynpro based. Work center views, if required subviews, and the common task level can be restricted by the authorization object SM_WC_VIEW. This authorization object is contained in the role SAP_SMWORK_BASIC_<WorkCenter>.
You may need to adapt this authorization object for instance in scenarios in which the user can select copied transaction types in subviews or views, such as Incident Management or Change Request Management.
Pls check security guide page 99
