How to do running aggr based on prompt value and how to or prompt?

Question

Hello guys
I have some requirements that I have a report that has measures and Months and Date..
1. I have to create dashboard prompts on months and dates in such way that users can select either that want to see monthly sales or daily sales.. So the two prompts should be "or" relationship that point to the same report. If user select month from month prompt, the report will return data at monthly level; if select day on day prompt, it should return data at day level..
2. Doing running sum based on the dates selected from the prompts.
If I select day prompt as between "Feb 12th 2009" and "March 1st 2009", the report should return sales data that is the sum of all sales between "Feb 12th 2009" and "March 1st 2009".. If user select month prompt as between "Nov 2008" and "Feb 2009", the report should show the sum of all the sales from "Nov 2008" and "Feb 2009".
How would I achieve both scenarios?
Any pointer will be greatly appreciated..

Hi.
Maybe you want to have dynamic group by in Answers report by choosing group by part from a dashboard prompt.
So, assume this example in which you have only one dashboard prompt that shows Day or Month character data.
Make dashboard prompt:
edit column formula: 1
control: drop-down list
show:
SELECT case when 1=2 then TIMES.CALENDAR_MONTH_DESC else *'Day'* end FROM "Normal model"
union all
SELECT case when 1=2 then TIMES.CALENDAR_MONTH_DESC else *'Month'* end FROM "Normal model"
default to - specified value: Day
set variable - presentation variable: pv_dyn_group_by
label: Group by
Now make report in Answers and we'll use dynamic column for group by depends on our presentation variable (Day or Month):
/* column 1 */
label:
I don't know how to dynamicly change column label (Month or Day) so I put just label Dynamic group by.
column formula:
case when '@{pv_dyn_group_by}' ='Day'
then EVALUATE('TO_CHAR(%1,%2)' as varchar(20), TIMES.TIME_ID, 'dd.mm.yyyy')
else TIMES.CALENDAR_MONTH_DESC
end
/* column 2 */
AMOUNT_SOLD
/* column 3 */
RSUM(AMOUNT_SOLD)
Test:
In both cases we get the same result of RSUM in the end. First we group by a TIMES.TIME_ID if we choose 'Day', second by a TIMES.CALENDAR_MONTH_DESC if we choose 'Month'.
Is that you want to?
So if you want to see month or day values to choose it (between part) you must make second prompt with something like this in show SQL results:
SELECT case when '@{pv_dyn_group_by}{Month}'='Month' then TIMES.CALENDAR_MONTH_DESC end || case when '@{pv_dyn_group_by}{Day}'='Day' then EVALUATE('TO_CHAR(%1,%2)' as varchar(20), TIMES.TIME_ID, 'dd.mm.yyyy') end FROM "Normal model" order by 1
The name of the second prompt is: '@{pv_filter}{Month}'
That will display 'Month' or 'Day'. I don't know better solution :-)
Similar is to make a between 2 prompts.
After then you must modify filter in Answers to get OR (between dates ot between months)
