During an insert operation, the grid attempted an extract operation on the update channel to verify that the new record does not exist, returning a record busy error. The record is marked as busy, the current row is returned to the edit state, and program intervention is awaited. The application should be set to either cancel the edit operation or retry the update by sending an "End Edit" message to the grid control.

During an insert operation, an EXTRACT was attempted on the update channel to verify that the new record does not exist and the operation succeeded.
