You need to goto Dev Studio>Configure>System>Refactor>Classes. On the landing page, select ‘Delete a class’ and provide the class for the data type and continue moving forward with the wizard. After the wizard completes, all associated classes and instances of the data type will be deleted from the system.

@Satya K To delete a data type in Pega, ensure it is not being used in any rules like data pages, activities, or reports. First, try deleting it from App Studio under Data Types. If that doesn’t work, go to Dev Studio > Records > Data Model > Data Type, locate the data type, and delete it after ensuring no references exist. If the data type is linked to a dedicated database table, go to Configure > Data Model > Database Class Mappings, find the table, and delete it if it’s not needed. Clear the cache using Actions > Clear Cache and revalidate the application under Application > Validate. If the data type still exists, check with the database administrator to drop the table directly from the database. Always verify there are no broken references before proceeding

Hi @Satya K,

If it is not deleted by using App studio then delete all the rules which they have created when you created the datatype.

To delete a data type, you need to remove all the rules associated with it. This includes:

  • Class rules
  • Data pages
  • Report definitions
  • Database tables
  • History classes

You can find the data type name using the Elastic Search box. Make sure to select the “Contains All Rules” filter. This will display all the rules linked to that data type. You can then open each rule and delete it. Once all associated rules are deleted, the data type will be deleted from the application.

Let me know if you have any questions!

Best Regards,
