When using the Database Transporter to import custom columns from one database to another, the associated tabs become unavailable in Manager with the error "You do not have sufficient permissions to view data in the category 'Custom'".
The reason for this behavior is because the actual permissions on the column do not transfer with the Database Transporter tool and will need to be recreated manually for each extended column.
The quickest way to replace missing permissions is to copy them from an existing column and paste them onto the new column. After completing this step and committing the changes to the database, you will then be able to view and edit the information in Manager.
1. Copy permissions from an existing column.
2. Paste permissions onto custom extended column.
3. You will now be able to access and view the column information from Manager.
