Description

Reenables enforcement of constraints when records are posted.

Call EnableConstraints to turn on constraints previously disabled by a call to DisableConstraints.

Note: Calling EnableConstraints decrements a reference count. When this reference count is zero, constraints are enabled for the dataset. To prevent accidental disabling of constraints, always follow a call to DisableConstraints with a matching call to EnableConstraints.
