The most common cause is when a job uses ILE activation groups and the OVRDBF ignores activation groups.
The most likely correction is:<pre>
OVRDBF FILE(FILE) TOFILE(FILE) MBR(*ALL) OVRSCOPE(*JOB)</pre>
But that might be an improper scope. It might affect other programs in the job that should not see the override.
Test the change carefully.
