The permission levels that we can set for a non-administrator User on a specific Environment are: tRead Allow / Read Deny tShow Latest Allow / Show Latest Deny tWrite Allow / Write Deny tWrite Delete Allow / Write Delete Deny tFull Control Allow / Full Control Deny tEnvironment Admin Note that DENY permission will over-ride the ALLOW permission levels. In the System Administrator portal, we can set this up either using the ENVIRONMENT tab or USERS tab.
