If the dataset is checked out and the rollbackCheckout is True, the dataset's changes will be roll-backed and then the delete operation takes place, but if the rollbackCheckout is false, The changes will be checked in as a new version and then the deletion operation is executed.
public DeleteDataset ( System.Int64 datasetId, string username, bool rollbackCheckout ) : bool
datasetId System.Int64 The identifier of the dataset to be checked-in.
username string The username that performs the check-in, which should be the same as the check-out username.
