Change retention of file to retention of volume?

[ Edited ]



I would like to change the retention of a file to the retention of a volume.



a volume for which at the start no retention was defined, now got retention "infinite".


In this volume reside records with a retention date in the past.


I know how to set the extension of these records to a certain date up to 2071,

but I would like to set the retention of these records to the extension of the volume, that is to inifinite.


How can I do this?


Thanks a lot,
