The DataPointValueService class provides the DataPointValueService.removeValues() method to delete one or more data point values. You can provide one or more DataPointValue instances corresponding to the data points that you want to delete. A DataPointValue instance has a unique uidPk value corresponding to the location of the data point value in the database. When you use the DataPointValueService.removeValues() method to delete data point values, such as cart gift certificates, order data, or customer profile, the system deletes data point values from the database. For example, when you use the DataPointValueService.removeValues() method to delete your street address, the system deletes the street address from the database.
