Customized Data Classes

You use the Customized Data Classes page of the Customization Project Editor to manage DAC items in a customization project.

Note:
A DAC item contains data in XML format used by the platform to create an appropriate extension for the original data access class.

The Customized Data Classes page displays the list of DAC items for existing data access classes of MYOB Acumatica added to the project.

On the page, you can perform several operations with the customized data access classes, as described in the following topics:

Note:
You cannot create a custom data access class on this page. Instead, you have to use the Code (AU204000) page of the editor. Custom classes are added to the project as Code items. See To Create a Custom Data Access Class for details.

You can use Microsoft Visual Studio to work with a DAC item of a customization project that is currently published. During the project publication, the platform creates the PX_Objects_<DACItemName>_extensions.cs file with the item content in the App_RuntimeCode folder of the website. If you make changes to the code in Visual Studio, you have to update the item in the customization project. See Detecting the Project Items Modified in the File System for details.

Note:
You can customize DAC items for the Customer Portal as well. For details on the portal, see Customer Portal.
