Data Access Class

A data access class (DAC) is used to represent a database table in the code of MYOB Acumatica. If a DAC is bound to the database, it must have the same class name as the database table. A DAC must be declared with the public access modifier to be correctly recognized by the MYOB Acumatica Customization Platform. A DAC is inherited from the PXBqlTable class and the IBqlTable interface and contains data field declarations.

You can use Customization Project Editor to do the following:

• Create a new DAC
• Add a custom field to an existing DAC
• Customize the declaration of a data field of an existing DAC

For detailed information on customizing data access classes, see the following topics:

See Data Field for detailed instructions on the customization of a data field.
