RE: BPCS 5.1 Issues upgrading to OS/400 V5R1

The Biggest issue is an SQL error when the SQLCODE stops supressing errors. If 
the PTF you loaded doesn't do the trick try the following to system file 
QAQQINI:

1) CRTDUPOBJ of QSYS/QAQQINI original template into QUSRSYS library. This step 
can be skipped if the file already exists (or the command will fail and the 
error can be ignored):
> CRTDUPOBJ OBJ(QAQQINI) FROMLIB(QSYS)
OBJTYPE(*FILE) TOLIB(QUSRSYS) DATA)*YES)

>From a Interactive SQL session enter:
2)> DELETE FROM QUSRSYS/QAQQINI
WHERE QQPARM='SQL_SUPPRESS_WARNINGS' 

3)> INSERT INTO QUSRSYS/QAQQINI
VALUES('SQL_SUPPRESS_WARNINGS', '*YES', default)

Note, by default, all jobs on the system will load the
QAQQINI file from library QUSRSYS. Individual jobs can
change the library used to load this file by using the
CHGQRYA (Change Query Attributes) command and the QRYOPTLIB
parameter. 

Good Luck,
