Error : qsh: 001-0014 Comand /QOpenSys/usr/bin/7z not Found

Hi all

From some days, a program that run the " QSH CMD('7z e -y -tgzip

/FID/xww_20251210.txt.gz -o/FID/ > Eur_PrCo.log'), receive the error "qsh:
001-0014 Comand /QOpenSys/usr/bin/7z not Found"

If i run use WRKLNK '/var/opt/p7zip/bin/*' and use option 8 next to the '7z'
script i see CCSID = 819

If in run :

QSH + Enter

And then in run "7z" and Enter i receive qsh: 001-0014 Comand
/QOpenSys/usr/bin/7z not Found

Which could be the problem ??

I also checked that the paths listed in 7z file exist

Thanks in advance
