If you have amended a custom SQL view, e.g. one prefixed UDEF, to add extra columns, then to pick up the new columns in an existing AOI template will require creating a new AOI custom template (using your newly amended SQL custom view) and deleting the old AOI template, if needed.
Old custom AOI templates can be deleted as follows:
Open AOI Administrator via the windows start menu
Click Custom Views
Click Manage Custom Views
Select the check boxes of the relevant view(s)
Click Delete Selected.
Create a new AOI custom template using the amended custom view
