Today I am going to analyse form and datasource methods in standard AX application and find the most and the least overridden.

Form
Overridden rate is calculated as the ratio of the number of forms, where a method is overridden, to the total number of forms.
What does the diagram say?
Not surprisingly, init method is almost always overridden. run, close and closeOk methods are often overridden. All other methods are rarely overridden.
The following methods are never overridden in standard application:
addHistory
blockPersonalization
closedCancel
controlMethodOverloadObject
copy
getActiveWorkflowConfiguration
getActiveWorkflowTrackingStatus
getActiveWorkflowWorkItem
initWorkflowControls
loadUserSetting
reload
send
setApply
skipSaveUserSetting
updateWorkflowControls


Datasource
Overridden rate is calculated as the ratio of the number of datasources, where a method is overridden, to the total number of datasources.

Top overridden methods are:
init, active, executeQuery, write, validateWrite, initValue, delete, linkActive, create.
All other methods are rarely overridden.
The following methods are never overridden in standard application:
defaultMark
findValue
markAllLoadedRecords
refreshEx


Conclusion
This standard application statistics reflects what is usually overridden by a developer on a regular project:
- init, run, close methods on a form
- init, active, executeQuery, write methods on a form datasource.
