Issue Context:
* The custom field is not being updated by the Price Rule even after enabling triggers in the CPQ Package Settings.

Solution Steps:
* Navigate to Setup > Installed Packages > Salesforce CPQ.
* Locate the Post Install Scripts section and click Run.
* Test the Price Rule again to verify that the custom field is updated correctly.
