Option 1: Add parameter to dimension filter

Option 2: Create calculated field referencing parameter

Step 1: Creating the parameter

7. Click OK.

Step 2: Creating the calculated field

2. In the Calculated Field dialog box that opens, do the following, and then click OK:
   1. Name the calculated field. In this example, the calculated field is named "Region Parameter Filter"
   2. In the formula field, create a calculation similar to the following:

      [Region Parameter] = [Region]
      OR [Region Parameter] = "All"
      

Step 3: Creating the view

Additional Examples

Numeric Parameter

SUM( [Sales] ) >= [Sales Parameter]

Boolean Parameter

SUM( [Sales] ) >= 100000
OR NOT [Show Only High Sales Parameter]

This calculation will return True when SUM([Sales]) is above 100,000 or if False is selected in [Show Only High Sales Parameter]. The operator NOT converts False into True, and when a value is selected in a parameter then that value applies for every record in the data set.

Date parameter

[Order Date] >= [Start Date Parameter]
AND [Order Date] <= [End Date Parameter]
