Column filters versus parameter filters
The distinction between a column filter and a parameter filter is whether Birst will add the filter into the WHERE clause. Column filters affect the WHERE clause and update the result set appropriately. Use a parameter filter to use the response value for other capabilities, like controlling colors or doing what-if analysis using constants.
Creating parameter filters
In Dashboards 2.0 you explicitly create parameter filters. See Dashboard Filters.
To create a parameter prompt in Original Dashboards, click a prompt to open the Prompt Properties dialog. Click Change parameter name for report expression prompts and specify a new name in the Parameter name field.
