Level check error while overriding in RPGLE

[b.reddikumar]

In below program I am trying to override the file B1 to B2. But I am getting level check error

Level check on file B2 in library BANDARU901 with member B2.
Error message CPF4131 appeared during OPEN.



FB1 IF E K DISK EXTFILE(FILENAME)

Dfilename S 20A
DMBRNAME S 10A
/FREE
Open b1;
Read b1;

read b1;
enddo;
Close b1;
*inlr=*on;
/end-free

Can you please help me in this?

HI Reddi,

but the b2 file is the same as b1, with the same level?
Because if no you can't override b1 on b2.

Without the definitions of the files we can't really help much - except to say you could avoid it if you used SQL.
