Example

Executing the example requires that the repository contains a table with the DataTable identifier. The table contains a field with the ID identifier.

Sub UserProc;
Var
    MB: IMetabase;
    Table: ITable;
    Field: ITableField;
Begin
    MB := MetabaseClass.Active;
    Table := MB.ItemById("DataTable").Edit As ITable;
    Field := Table.Fields.FindById("ID");
    Field.Mandatory := True;
    (Table As IMetabaseObject).Save;
End Sub UserProc;

On executing the example it is prohibited to specify empty values in the ID field.
