Copy data and data integrity

The information that copy data copies to the target period can be incomplete or inconsistent with the product model. The copier classes have no mechanism to verify that the copied information is available in the target period. For example, you can copy a coverage that is no longer available into a new period. If you do, quote level validation and product model consistency checks ensure the integrity of data. When information is initially copied, the policy is in draft mode. Quote and bind validation ensure the integrity of the data.
