BPC and Drill to SQL Server Table

Hi Experts,

I am trying to drill through to a SQL server table from BPC.

Does anyone know the address to insert in the URL field when adding the drill through?
As per the help, I created a query and then a DQY file (source.qty), located in the correct BPC server location.  Tried inserting the file path name as below as an example

SERVER NAME /PC_MS/DATA/Webfolders/DEV__2015/CONSOLIDATION/QUERYFILES/source.qty

In testing, the result was a failed attempt to open the location with a prefix of http://.

http:\\ SERVER NAME /PC_MS/DATA/Webfolders/DEV__2015/CONSOLIDATION/QUERYFILES/source.qty

What's the correct syntax to access the query?

Any ideas?

Has anyone used this feature regularly to link to other data?
Trying to create a simple query and then add the parameters e.g. time entity account etc.

Thanks

Eyal
