Remarks

A data flow component populates and uses this collection to validate the columns in its IDTSInputColumnCollection100 or IDTSOutputColumnCollection100 when the ValidateExternalMetadata property is false or when the SSIS Designer is in offline mode.

The collection typically represents the columns of an external data source used by a source or destination component. Use of the collection allows the component to perform validation without an expensive, time-consuming round trip to the source itself.

For more information about implementing external metadata columns in components see Implementing External Metadata.
