Resolution

The tapes are scratched based on the retention rule defined in the RMF file  or the Expdt coded in the JCL.

In this case the tape should be scratched based on the retention rule defined in the RMF file which is 6SM   5RO0060 5CO1500 2BA0000.
The RTN-SCHED for this volume is RTN-SCHED(3) BY RMF is  6SM   5RO0060 5CO1500 2BA0000.
The tape was moved to the CO location on the 19/05/2021.

Type 5 retention does not look at the Keepdate, it will first check Move date  then the date that the volume was created.

If the tape is reread  Ldate and Ljob would have been updated and the retention would be recalculated. In this case it is normal for the tape not to be scratched on the 5 June 2025.
