How can I restrict users avaialable when setting up substitution?
WF_SUBSTITUTE can be used to implement certain restrictions for maintaining a substitute (from release NW2004S). For more information see . You can display the BAdI and related documentation from SE18, and an example implementation is available in class CL_EXM_IM_WF_SUBSTITUTE. If you use substitution profiles on the SAP application system, then you can link the substitute to the profiles in UWL. This enables you to link substitutes to specific tasks on specific backend systems. For more information, look for workflow substitute profile in online help.
