Column Level Security
You can determine which User Groups
have permission to see every field in every table. If you have recently added a field, you will need to set column security for your users to be able to see the new field.
First, you may wish to check that they have permission to see that table by checking the Table Security
To change column visibility, go to the table you want to change security for, then go to Admin > Manage Tables.
Find your table then click the link below it that says "column security".
You will see a table listing all of your groups on the left hand side with the names of the columns along the top.
If there is a check mark at the intersection of the two fields, that user group can see that column.
