To override the default IDD visualization and behavior for an IDC control:
Create the set of override XML files for the control.
Create a ZIP file containing the override XML files. You can use any name, as it will be stored in the IDC configuration section of the database. All configuration files must be in the root directory of the ZIP file.
In the IDD Configuration Manager, edit the IDD application associated with the control you want to override.
On the Controls tab, select the IDC control you want to override.
Click Edit.
In the Edit dialog, click Browse, select the ZIP file containing the overrides, and then choose OK.
Only when uploading the ZIP file containing the overrides for duplicate prevention control, a validation check will be performed on the selected ZIP file of pmc-config.xml and validation error messages are displayed, if any.
Save changes to the IDD application. If the IDD application is already deployed, the IDC control changes, including the overrides, are applied automatically.
