QTEMP issue... I need help resolving...

First a bit of detail. 
Lawson has their own program for printing POs. I didn't want to modify that
program, so I basically made an exit program that will create the PO how we
want it. Lawson's batch programs have interactive and batch pieces and I
don't know where interactive begins and ends. There is WAY too much code to
decipher. So... in my exit program, I need to know what POs to process, so I
take a copy of their work file and I use that to get all of the POs I have
to process. I thought I would put this in QTEMP with an override so that I
can have more than one running at a time. Well, somehow that override isn't
taking. When more than PO is in a jobq at a time, one company will get
another companies information. (Which obviously isn't good). This is the CL
program I run before I open my file:

             PGM

 

             CPYF       FROMFILE(CUPPO120) TOFILE(QTEMP/CUPPO120) +

                          CRTFILE(*YES)

             MONMSG     MSGID(CPF2817)

             OVRDBF     FILE(CUPPO120) TOFILE(QTEMP/CUPPO120)

             CLRPFM     FILE(QTEMP/CUPPO120)

             MONMSG     MSGID(CPF0000)

             CLRPFM     FILE(LAWMOD7/CUPPO120)

             MONMSG     MSGID(CPF0000)

 

             ENDPGM     

QTEMP is towards the bottom of my Libl, could that cause a problem? Is there
a better way to handle this? I can't change the file, but I can create
different members, could this be a solution? I hope this is enough detail. I
am looking for suggestions.

Thanks.
