CAC00507E LENGTH OF WORK AREA FOR TASK-RELATED USER EXIT IS INVALID.
Explanation
The task-related user exit was enabled with an incorrect length
for the transaction work area (TWA). The task-related user exit requires a
TWA with a length of 4096 bytes.
User response
Disable the task-related user exit and then reissue the EXEC
CICS ENABLE command with a value of 4096 for the length of the transaction
work area. The provided CICS exit enablement transaction automatically specifies
this value.
