The ADS compiler rejects a MODIFY statement with message
“DC159068 OPERATION NOT ALLOWED FOR SPECIFIED RECORD. STMT FLUSHED”
for a certain subschema.
MODIFY RECORD is not possible with the subschema used in this dialog.
When you get this message you should check if the record is a member of a set that is not defined in the subschema. If the record is a member of a sorted set, chained or index, and the set is not included in the subschema, IDMS will not allow the record to be modified since a MODIFY could change the sort key and require set maintenance.
