Restrictions for Numerical Functions

Restrictions for Numerical Functions

The numerical functions CUME, MOVINGSUM, and MOVINGAVG calculate running totals and averages on a row-by-row basis. According to the way you partition a pipeline, the order that rows of data pass through a transformation containing one of these functions can change. Therefore, a session with multiple partitions that uses CUME, MOVINGSUM, or MOVINGAVG functions may not always return the same calculated result.
