Working with Reporting Services Filters–Part 5: OR Logic

February 4, 2011

When you combine multiple filters, Reporting Services uses AND logic. Once upon a time, there was actually a drop-down list for selecting AND or OR between filters which was very confusing to people because often it was grayed out. Now that selection is gone, but no matter. It wouldn’t help us solve the problem that I want to describe today.

As with many problems, Reporting Services gives us more than one way to apply OR logic in a filter. If I want a filter to include this value OR that value for the same field, one approach is to set up the filter is to use the IN operator as I explained in Part 1 of this series. But what if I want to base the filter on two different fields? I  need a different solution.

Using the AdventureWorksDW2008R2 database, I have a report that lists product sales:

SNAGHTML139a4b29

Let’s say that I want to filter this report to show only products that are Bikes (a category) OR products for which sales were greater than $1,000 in a year.

If I set up the filter like this:

Expression Data Type Operator Value
[Category] Text = Bikes
[SalesAmount]   > 1000

Then AND logic is used which means that both conditions must be true. That’s not the result I want.

Instead, I need to set up the filter like this:

Expression Data Type Operator Value
=Fields!EnglishProductCategoryName.Value = "Bikes" OR Fields!SalesAmount.Value > 1000 Boolean = =True

The OR logic needs to be part of the expression so that it can return a Boolean value that we test against the Value. Notice that I have used =True rather than True for the value. The filtered report appears below. Any non-bike product appears only if the total sales exceed $1,000, whereas Bikes appear regardless of sales. (You can’t see it in this screenshot, but Mountain-400-W Silver, 38 has sales of $923 in 2007 but gets included because it is in the Bikes category.)

  1. Thank you so much for explaining the problem so lucidly. I was just about to go mad trying to filter my rows effectively.
