To tailor a software system to your business needs, you need the capability of assigning your own set of unique codes to a data field.
UDCs are a method of using table values to define the allowed values for an input-capable field without having to recompile a program.
JD Edwards World uses UDCs to provide:
A table of values used to validate entered data
A uniform description for each valid value
A method used in conversion programs
We provide a number of codes with each system, you might need to modify some of these and set up additional ones.
Many fields only accept UDCs. For example, if you enter a code in the Units of Measure field on the Journal Entries form, you can enter only a code that exists in the UDCs list for units of measure. When a JD Edwards World program encounters a UDC field, it checks the data the user enters against the field's table of values. If no match is found, the program issues an error message.
