UDCs added to benefit workpapers can be reported to the associated benefit reports or detail reports only.
UDCs are intended to tag benefits with additional detail. They aren't intended to pick up UDC data from other workpapers.
UDCs can't be added to all report types and can't be summarized. FBT Reconciliation Summary reports, for example, can't display UDCs.
UDCs added to the Employee workpaper are only available in the Employee workpaper and don't link to benefit reports or detail reports.
The UDC column in a workpaper can contain up to 255 characters (text), $99,999,999.99 (currency), 8 digits (integer), 99,999,999.99 (decimal) or from 1/01/1900 to 31/12/2030 (date).
