Transformation:

You are interested in the count of dates during the week when each salesperson sold less than 50 units, not factoring the weekend. First, you try the following:

Transformation Name `Pivot columns` `EmployeeId` `COUNTIF(Sales < 50)` `1`

You notice, however, that the blank values, when employees were sick or had vacation, are being counted. Additionally, this step does not filter out the weekend. You must identify the weekend days using the `WEEKDAY` function:

Transformation Name `New formula` `Single row formula` `WEEKDAY(Date)` `'DayOfWeek'`

If `DayOfWeek > 5`, then it is a weekend date. For further precision, you can use the `COUNTAIF` function to remove the nulls:

Transformation Name `Pivot columns` `EmployeeId` `COUNTAIF(Sales, DayOfWeek<6)` `1`

The above counts the non-null values in `Sales` when the day of the week is not a weekend day, as grouped by individual employee.
