1.5.9 Enabling the Update Allowed Option for a UDF
The Update Allowed option is used during event processing. You can assign values to a UDF when a UDE is processed. During event processing, the system assigns certain UDF parameters based on the execution query you have maintained in the Event Processing screen. You are allowed to assign UDFs only for those UDFs for which the Update Allowed option is enabled.
