Add a Table Extension to a Project – Fields

After the field is added to the table, you can select and drag it to an existing field group, or you can create a new field group and drag the field to it. The added field and/or field group will be shown in bold type, while the existing fields and field groups will be displayed in italic type.
The following is an example of adding the AccountNum field from AOT > Data Types > Extended Data Types to the Fields node of the FMCustomer.myExtension table.
