Hi Arul,
Compare the user group rights in DEV and PROD to see if there is any difference in access levels assigned or rights explicitly granted."Refresh Documents" right should be granted to refresh documents with the user group you are trying to refresh reports.
One route is migrate associated rights along with content, if that's the usual practice from your Admin team, check with them if rights are being migrated along with content. If your admin team specifies right s for DEV and QA separately then ensure above mentioned right is granted and ensure access to folders migrated is granted to the user group.
Thanks
Mallik
