AX7 / D3FO: Table extensions and their method sequence

You can create a table extension to extend a table's design and logic. You can add new fields, field groups, indexes, mappings and relations. You can also add new fields to existing field groups, change the label of a table field, change the Created By, Created Date Time, Modified By, Modified Date Time properties. In Microsoft Dynamics AX 2012, you could override the virtual methods of a table's base class to control the behavior that occurred during table operations, such as when creating, reading, updating, or deleting. In the current version, you instead use extensions to implement event handlers that are called from the base implementations of the table methods. The following table lists each table method and its events.

Published Table method

FinalReadValidation

N/A
FinalUpdateValidation

Validation events capture and return results by using the DataEventArgs parameter. The display and edit method modifiers are supported on table extensions.
