Recover SAP/R3
From Tranzman Documentation
Follow the steps below to recover SAP R/3 data.
Step 1
Restore the backup id file (the file with an extension of .anf or .pff) from NBU to the default SAP backup location.
i.e. /oracle/<SID>/sapbackup
Example: We have the file bezmwlru.pff from NBU which needs to be restored to the SAP Oracle TS2 instance. So we restore it to the required location of /oracle/TS2/sapbackup/bezmwlru.pff
