My SSRS report fetches data from my DATAWAREHOUSE.
The ASP.NET application I have is connected to an OLTP database.
I invoke the SSRS Report from my ASP.NET application and provide a parameter as CustomerID(this is an application key in datawarehouse) to my report.
Since my report is connected to my datawarehouse, I do not query my report databased on the OLTP's CustomerID. Instead I use my datawarehouse's surrogate key (CustomerDimKey). Now, in my report, I need to find the correct surrogate key for the CustomerID parameter, which I passed from my ASP.NET application!
My report already has a parameter as @CustomerDimKey(this is used across all the report sprocs). We used it for testing, but now we'll hide this as we have integrated it with the ASP.NET application.
I have already added a new parameter to the report as @CustomerID(this will have the OLTP's CustomerID), which will now get a value from ASP.NET.
I need to know a way to re-use the @CustomerDimKey report parameter, which should now get value from a sql statement or a sproc once the report is requested. Based on the value contained by the @CustomerID parameter.
