The following data identifies sales figures by salespeople for a week:
EmployeeId | Date | Sales |
---|---|---|
S001 | 1/23/17 | 25 |
S002 | 1/23/17 | 40 |
S003 | 1/23/17 | 48 |
S001 | 1/24/17 | 81 |
S002 | 1/24/17 | 11 |
S003 | 1/24/17 | 25 |
S001 | 1/25/17 | 9 |
S002 | 1/25/17 | 40 |
S003 | 1/25/17 | |
S001 | 1/26/17 | 77 |
S002 | 1/26/17 | 83 |
S003 | 1/26/17 | |
S001 | 1/27/17 | 17 |
S002 | 1/27/17 | 71 |
S003 | 1/27/17 | 29 |
S001 | 1/28/17 | |
S002 | 1/28/17 | |
S003 | 1/28/17 | 14 |
S001 | 1/29/17 | 2 |
S002 | 1/29/17 | 7 |
S003 | 1/29/17 | 99 |
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 |
|
---|---|
Parameter: Row labels | EmployeeId |
Parameter: Values | COUNTIF(Sales < 50) |
Parameter: Max columns to create | 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 |
|
---|---|
Parameter: Formula type | Single row formula |
Parameter: Formula | WEEKDAY(Date) |
Parameter: New column name | '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 |
|
---|---|
Parameter: Row labels | EmployeeId |
Parameter: Values | COUNTAIF(Sales, DayOfWeek<6) |
Parameter: Max columns to create | 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.
Results:
EmployeeId | countaif_Sales |
---|---|
S001 | 5 |
S002 | 4 |
S003 | 4 |
