What is a fixed date filter?
A fixed date filter is not based on today's date. It can be a specific day, week, month or year. It does not vary depending on today's date. Example of fixed date filter:
What is a relative date filter?
A relative date filter allows you to apply time-based filters to any date column in your data model. For example you can use the relative date filter to show only sales data that's happened within the last 30 days (or month, calendar months, and so on). When you refresh the data the relative time period automatically applies the appropriate relative date constraint. Examples of relative date filter: Last calendar month, Last 30 days, Last month and more.

Why use relative date filters for your recurring PowerPoint report?
In this example we need to prepare a report displaying the previous month's sales at the beginning of each month.
Without relative date filter
Using a fixed date filter August 1st to August 30th to produce the August sales report in early September:
- When updating the PowerPoint presentation in October (one month later) with the September results the filter will still have the dates originally selected: August 1st to August 30th
- You would need to import all your visuals all over again each month. This is time consuming.
With relative date filter
Using a a relative date filter last calendar month to produce the August sales report in early September:
- When updating the PowerPoint presentation in October (one month later) with the September results the filter will be for the last calendar month which is now September 1st to September 30th
- You do not need to import the visuals again. Instead you can copy the PowerPoint file and within PowerPoint choose to update all the visuals in a click from the Update Links panel
