Trying to setup a custom parameter (to work as a flag) in SSRS

Hi,

Thanks for looking into this thread.

I have a SSRS report which displays results for two regions say A and B. Now, I want to set up a flag (0 for A and 1 for B), providing users an option to select either A or B or Both from SSRS parameter.

Behind the scene, I have a stored procedure which excepts A and executes query from a view related to A (I have different views for A and B). Similarly, on selecting B, query gets executed for view B.

Now, for 0 and 1 individually, it works fine calling respective views / queries but I need to set default as both (saying - 'A / B' in parameter).

I know the use of SP with a Split function but as I am trying to acheive this with a flag and SP having individual queries. How to achieve this functionality in SSRS?

Thanks for your help !
