Answer Posted / abhishek
As per me ...Whenever we compile a PF system generates a Rcd
Fmt level identifier , which is a unique no . for record
format . If this file is being used by some pgm and we
change the structure of our PF for ex. we add one more field
or change some existing field length then and compile the PF
, then system generates a new code for the record FMt .
Level check occur when we change PF structure and do not
compile pgm which is using that file . Because the program
will be using the old identifier.
If we want to check identifier then we can ue command DSPFD
for file and for program we can use , DSPPGMREF to see the
FMt level identifier which is used by program for that file.
