I am still new with CPQ. So far we able to set validation rules if certain field contain certain value but we cannot set validation rules to detect field changes.
The requirement is to lock certain fields in Quote Line whenever checkbox in Quote is set to true. I able to create Product Rule to identify if the checkbox in Quote is set to true but how I can detect changes on certain field.
In Error Condition , there is no IS CHANGE operator. Is there anyone here using CPQ , how you guys detect the changes on the field and fire the validation rule.
