If you want to know who deleted the object in IFS. You have to do few steps.
1. Create output file in appropriate format
CRTDUPOBJ OBJ(QASYDOJ5) FROMLIB(QSYS) OBJTYPE(*FILE)
TOLIB(YourLibrary) NEWOBJ(OutputFileName)
2. Use DSPJRN command to extract audit records into file created in previous step
DSPJRN JRN(QAUDJRN)
RCVRNG(AuditLibrary/Receiver *CURRENT)
JRNCDE((T)) ENTTYP(DO)
OUTPUT(*OUTFILE) OUTFILFMT(*TYPE5)
OUTFILE(YourLibrary/OutputFileName)
Be aware of using correct journal receiver/s which contains time when object was deleted.
3. Use SQL to show only records you are interested. In this case everything in directory /QFPNWSSTG
SELECT Dotstp,
Dojob,
Douser,
Donbr,
Doradr,
Dorport,
Dootyp,
Doasp,
Dopnm
FROM YourLibrary.YourFile
WHERE Dopnm LIKE '/QFPNWSSTG/%';
