spro_admin tcode

Dear Experts

we have query spro tcode in Quality server with only one module access

we have done with SPRO_ADMIN command but when we have created role and add that customization it works fine

but there is a tab we need to hide that tab bcaz once some body click on that whole spro comes into picture

i have tried with SHD0 to hide that tab it didn't work

we need to remove SAP Reference IMG tab

i need some suggestion so i could able to disable or hide that

Regards
