Recently I have encountered this situation where few of the user were not able to see their Responsibilities on their home page after applying an iRecruitment related patch.
To resolve this problem I ran the concurrent program “Workflow Directory Services User/Role Validation” with below parameters:
p_BatchSize – 10000 (Default Value 10000)
p_Check_Dangling – Yes (Default value No)
Add missing user/role assignments – Yes (Default Value No)
Update WHO columns in WF tables – No (Default Value No)
This concurrent program syncs all the user and role related WF tables with latest information viz., WF_LOCAL_ROLES, WF_LOCAL_USER_ROLES, WF_USER_ROLE_ASSIGNMENTS etc.,
