How to rollback changes to VSAM file on CICS?

I'm using EXEC CICS SYNCPOINT and EXEC CICS SYNCPOINT ROLLBACK to commit/backout updates to VSAM and DB2 tables when abend happens. However, only updates to DB2 tables are backed out not on VSAM. Am I missing something? CICS parameter RLS is set to RLS=NO.

    If you are using non-RLS files then you need to set the attributes correctly on your FILE definition.

    See the following page within the CICS documentation that describes about file recovery:
