When you are adding a User Defined Table (UDT) you can define your own custom columns for the UDT.

UDTs are RAMM database tables which you have defined yourself so that you can use RAMM to manage your asset and condition data which are not in the standard RAMM Set.

Custom Columns Are Highly Configurable

You can create Custom Columns of the standard RAMM column types such as text, date, Boolean and so on. You can create Calculated Custom Columns which default based on selection criteria you have defined. You can also associate attributes with values in a Custom Column.
