Error was displayed when viewing the details of the Internet Expense notification with DFF(Additional Details) using a value set with Validtion Type Table. I created value set named PR POSITION. Value set included condition where/order by fnd.user_id = (SELECT fnd_profile.value('USER_ID') . The intention was to limit the choice of the preparer to only the position name assigned to himself in his HR Assignments > Position name.
Error message = Value Sr Business Sys Analyst - Expenditure Automation Sys Mgt for the flexfield segment Position does not exist in the value set PR POSITION.
