Dashboard Prompt using values not from the table

Question

Hi,
I have a requirement from the client to design a dashboard report like the following.
Dashboard prompt will have 4 filters, three filters come from the table, but the fourth filter will have 3 values not from the table. The fourth filter will have values like "Report with Sales Amount", "Report with Purchase Amount", "Report with both Purchase and Sales". I have three different Table reports designed for each of the fourth filter choices. But how do I implement it, both in the dashboard prompt as well as navigating to the rite report based on the selection.
Is my approach correct.
Thanks for your time and help.

Answer 1

The fourth prompt where you have "Report with Sales Amount", "Report with Purchase Amount", "Report with both Purchase and Sales" you pull a dummy column into the prompt and write a sql in show.
would be something like
SELECT Case when 1=0 then "Dimension- Customer"."Cust Name" else 'Report with Sales Amount' end FROM Sales UNION SELECT Case when 1=0 then "Dimension- Customer"."Cust Name" else 'Report with Purchase Amount' end FROM Sales
and in the prompt set a presentation variable say var_criteria
Now create report2 for with a some randomn column and another column will have the values that you want to display for example 'Report with Sales Amount'
Create a filter on the 2nd column and reference the presentation variable var_criteria and default it to 'Report with Sales Amount'
On the dashboard page in the section place the report and enable guided navigatoin by selecting report 2.
Please let me know if you have any questions.
thanks,
