Understanding UDCs for Job Cost
You can customize many of the fields in JD Edwards EnterpriseOne Job Cost by setting up user defined codes to meet the needs of the business environment. You identify user defined codes by the system code and the user defined code list. For example, the represents system 51 (Job Cost) and user defined code list TO (chart type).
The system stores UDCs in tables related to a specific system and code type. These tables determine what codes are valid for the individual fields in the system. If you enter a code that is not valid for a field, an error appears. For example, you can only enter codes in the Business Unit Type field that exist in the table for System 00 and code type ME. The system stores the tables for all of the user defined codes in the User Defined Codes table (F0005).
