DATE (bucket function)
The DATE bucket function generates a single date value.
When the DATE bucket function is used, the comparison data is sent unfiltered to bucket generation. Use this bucket function when the standardization function is DATE or GRDATE and the generation function is one of the following: ASIS, DTY4SMD, DTY4MM, DYMMDD. If you want to apply one of the other generation functions to a date, you must use the bucket function ATTR.
