You can only remove lookup values if they are set up for a specific security group. However, you can stop all lookups appearing in lists of values.
Note: You must be using Security Group Enabled security to categorize lookups by security groups. See: Categorizing Information By Security Groups
In the Application Utilities Lookups window, do one of the following:
Enter an end date if you want to prevent users selecting this value after a certain date.
Disable the code by un-checking the Enabled check box if you want to prevent users selecting this value with immediate effect from the current date.
Change the meaning and description to create a replacement lookup.
If you add, disable, or change the meaning of a lookup, users must log out and log back in again for your changes to take effect.
In the Application Utilities Lookups window, select the lookup type which has lookups for a specific security group.
Check the Global Security Group check box.
This removes all lookups which have been set up for the security group linked to your current responsibility. Predefined lookups are not removed.
If you add, disable, or change the meaning of a lookup, users must log out and log back in again for your changes to take effect.
