I had added some new method to an existing table thru AOT and it shown as (usr) model
I need to fix this customization to secure it from deletion.
I had faced one problem with my company administrator (I'm not sure what happen exactly) but while he was doing a database backup from live server to test server (my work only in the test server) all my previous work had been canceled like new added custom tables, new methods added to an existing tables, etc.
I knew one fast solution it to import the saved .xpo for any custom projects I did before but I want another solution or suggestion to prevent like these problem to happened again.
