Presentation variable in dashboard prompt

Question

Hi All
I have a report on a dashboard page which navigates to another report on a different dashboard page (on the same dashboard). The
first dashboard page has a prompt which needs to be passed as a filter to the navigated report i.e. Report1 on dashpage1 has Level1 prompt
whose value must be passed to Report2 on dashpage2 which has Level2 (hence Report2 must show Level2 values for the passed Level1).
1) I tried setting prompt1 on first page scope to Dashboard but it didn't help.
2) I am trying to set a presentation variable 'level1_val' in the prompt1 and then in report2 say Level2 = @{level1_val} in Answers (filter->add presentation variable, I did not provide a default value). But when I navigate, Report2 shows no results. On adding the filter value, I noticed that the condition in Report2 is Level1=level1_val (Its taking level1_val presentation variable as a string and matching it to the Level1 prompt value). Level1 prompt value is a string. Is there a format say '@{level1_val}' that I should use in the column filter (I've tried this too)?
Thanks

You are using dashboard url option in the code from the report 1 to call dashboard page 2 (with report 2).
You have only dashboard prompt for level 2 in the dashboard page 2?
1. If you put in the filter of the second report column is equal to presentation variable that you set in the first dashboard prompt this will not work, you'll get COLUMN is equal to pres_var. When you are using DASHBOARD URL you need to pass presentation variable to the filter of the target (dashboard page prompt). If the target page prompt does't exist the parameter is parsed to the filter of all reports (or just one) that has this COLUMN set to is prompted.
2. Go to the report 2 and set level 1 is prompted.
3. Go to the report 1 and write dashboard url correctly with passing presentation variable like:
'<--a href=http://.../saw.dll?Dashboard&PortalPath=/shared/.../_portal/Yourdashboard/&Page=Yourdashboardpage
&Action=Navigate&col1=TABLE.COLUMN&val1='||REPLACE(REPLACE('@{pres_var}', ' ', '+'), '+', '%2B')||'>Link
<--/a>'
TABLE.COLUMN is a target column to which you want to pass parameter (presentation variable), it can be on the prompt or just set to is prompted in the report 2.
But if you want to pass presentation variable to the filter of the dashboard page 2 prompt which is level 2 this could be a problem (if you are using SQL result option in the dashboard prompt in the second page to show level 2 and want to filter it by pres_var that you set in the first page prompt with level 1 this is not possible, because you can only pass parameter to the page prompt field, but you can set dummy hidden prompt in the second page and pass level 1 to it and then set new presentation variable that is available only for the second page and then use this presentation variable as the filter in the second page prompt for level 2 in the filter to show only level 2 values for the level 1 value, this method is explained in the link below).
Try to fix it now.
