If the column has set property FormulaForInsert, value will be inserted in the column at the record creation, even if it does not have set property EditInInsert. Although the column is not filled in by user in the form, it is calculated by formula. Similar rule is used for the update of existing records.

System columns are columns created by ObjectGears system. They are displayed in grey italics in the page with list of columns.

 

Value is in a localized form in queries that read data from ObjectGears system tables (e.g. roles). By settting up property Localize of the corresponding column to TRUE, only value for the current user language will be displayed.
