If you want to know when specific object or objects in specific folder was saved. I didn't find answer in BRMS but with little help from SQL you can get answer.
SELECT DINAME as Path, LINAME AS File, LITYPE as File_Type, LISASP as ASP, LISOWN as Owner, LISIZE as Size,
DILNAM as BRMSList, DISVT as SaveDate, BKVOL as Volume, BKHSYS as System, BKHSRL as Release, BKLSEQ as Sequence,
BKHDEV as Device, BKHEXP as Expiration, BKHGRP as ControlGroup, BKHMC as MediaClass, BKHDUP as Duplicate,
BKNAME as JobName, BKJNBR as JobNumber, BKUSER as JobUser
FROM QUSRBRM.QA1ALI2 LEFT OUTER JOIN QUSRBRM.QA1ADI2
ON QA1ALI2.LIDKMAIN=QA1ADI2.DIDKMAIN AND QA1ALI2.LIDKSYS=QA1ADI2.DIDKSYS AND QA1ALI2.LIDKJNBR=QA1ADI2.DIDKJNBR
JOIN QUSRBRM.QA1AHS
ON QA1ALI2.LIDKMAIN=QA1AHS.BKDKMAIN AND QA1ALI2.LIDKSYS=QA1AHS.BKDKSYS AND QA1ALI2.LIDKJNBR=QA1AHS.BKDKJNBR
WHERE DINAME like '/IDAT001/sftp_trf%'
AND LINAME like 'S160%'
ORDER BY DIPROC DESC;Result can be something like this :
