Nice article, but would have liked a mention that using the Multi-phase Datapump to transform data will switch the datapump to row-by-row processing. This is something that people should be aware of and can lead to data loads taking much longer than if a normal datapump copy column task is used.

Also, you don't have to use all the phases. In a lot of my packages I use just the PumpComplete phase. The VBScript in this phase uses the DTSTransformPhaseInfo object to capture the number of rows exported to the file. This object also has an ErrorRows property that holds the number of errors encountered.
