Understanding UDC Tables
You use the User Defined Codes program (P0004A) to create and customize UDCs and UDC types. The program stores UDC information in the following tables:
User Defined Code Types (F0004)
User Defined Codes (F0005)
For more information on customizing UDCs, see "Customizing User Defined Codes" in JD Edwards EnterpriseOne Tools Foundation Guide.
