Answer / shobhit
As per my knowledge…
When ever we compiled physical file, the system generates
unique code or level code for identifying the file.
And when ever we compiled RPG program using that file, the
compiler store the Level code of physical file for further
reference. That’s call lever check.
Ex: If you compiled the RPG program and after that made
some changes in physical file, and then call the RPG
program without compiling again it will give the Level
check error.
Please correct me if I am wrong 

Whenever PF is compiled, the system generates unique code
for identifying the file for future reference.
When we compile the Program that uses the PF, will use that
unique code of the PF.
If we now call the program, then its run successfully.But
if we change the PF and recompile the PF, the system
fgenerates a new unique code for that PF. So, our program
Don't have this unique code and hence terminates abnormaly
with a Level Check error.
The solution of Level Check error is when ever it happens
we have to either compile the PF with Level Check parameter
value *NO or we have to compile the program again.
Please let me know anyone, if i am wrong.

Answer / 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.
