Hello,
Web Dynpro Component assigned to pop-up "Forward Work Items" is IBO_WDC_INBOX.
Its view is V_FORWARD.
Context field AGENT (attribute) with the search-help makes part of node context FORWARD.
For this attribute, dictionary search-hep is IBO_SEARCH_USER. Its corresponding search-hep exit is IBO_F4IF_SHLP_EXIT_USER.
Make an implicit enhancement for this function module (there is no user-exit) in order to manage control-step SELECT.
Regards.
Laurent.
