Crosstab KPI expected to display results week-wise is not working. Why?

Crosstab KPI expected to display results week-wise is not working. Why?

One among the many causes for the Issue is: The measures selected in the KPI are dimensional measures and there are no base measures to display week wise. If you add one base measure, the cross tab KPI should work as expected. If you require further assistance, please contact Support team.
