Chain Of command – Forms – Dynamics 365 for Finance and Operations – X++

Chain of Command now supports the more scenarios for the extensions on forms:

Now you can wrap the methods on forms, Forms data sources, Datafields and on form control methods.

1. Forms
2. Form Data Sources
3. Form Controls
4. fields in data sources

Below is the complete example of Form Data source and just a code snippet for the rest. In below example we are updating the ratingmodel based on our custom logic that is global variable on the form.

Note: use element.FormToExtendVariable to access the form variables and datasources

Use element.FormToExtendMethod() to call the form methods

 

1. [ExtensionOf(FormStr(FormName))] // for form extension
2. [ExtensionOf(FormControlStr(FormName,FormControl))] // for form control method extension
3. [ExtensionOf(FormDataFieldStr(FormName,FormDataSource,DataField))] // for form datasource method extension
4. [ExtensionOf(FormDataSource(FormName,FormDataSource) // for form data source extension
