Understanding Deletions in the Repository

When an object is deleted from the repository within Crystal Reports, it is not truly deleted from the database itself. It is marked as deleted so that it will not show up in the Repository Explorer, but the object still exists within the physical database. This marking of a deleted object is often called flagging as dirty, or logical deletion. This allows the report designer to roll back the object to make it visible again if it was accidentally deleted.

Because objects are never truly deleted from the underlying database, the objects still take up space. To save that space, the objects must be physically deleted. To accomplish this, the report designer will have to use a database utility to physically delete the objects. For more information on physical deletion for your database, see your database documentation.
