An admin has created a validation Product Rule that must display an error message upon...

 Issue:

The validation error message appears immediately after a user sets a specific value in the Configuration Attribute, even before saving.

 Solution:

Setting Apply Immediately to False ensures that changes in Configuration Attributes do not trigger immediate validations. Instead, validations occur only upon clicking Save.

 Why Other Options Are Incorrect:

A: Evaluation Action does not exist as a field for Product Rule Error Conditions.

C: Changing the Apply Immediately field for Product Options does not affect the Configuration Attribute's behavior.

D: Setting Evaluation Event to Save applies to the rule's scope but does not address Configuration Attribute settings.

 Salesforce CPQ Reference:

Configuration Attribute Settings are explained in CPQ Configuration Attribute documentation ​.
