The NLQ window automatically selects any one of the date columns present in the data for MoM or YoY calculations. However, when the user has a dataset with multiple date columns, he/she should be given the option to select which date column to use for calculations. This is a must to ensure accurate calculations.
The above-mentioned Date Column Selection option is added, it will be available soon in next release. Keep an eye on the announcements section to know more about the latest improvements in Phrazor.
