Modifying UDFs
The range of UDF properties you can modify depends on whether the field has been used. A UDF is considered used if it appears on the UI and at least one value has been stored for it in the database.
If the UDF is used, you can still modify the following properties:
• Description
• Side Label
• Column Label
• Value list (for Combo type UDFs only)
• Lookup Reference, Stored Search, Stored Search Return (for Short and Long type UDFs only)
If a UDF is not used, you can modify the following additional properties:
• Mandatory
• Display Length
• Decimal Precision (for decimal type UDFs only)
You can delete a UDF if it has not been used.
