Passing OLAP Parameters Within a URL

Hi there!

My report uses an OLAP query with a (multi-valued) parameter, the MDX generated query is something like "...ON ROWS FROM ( SELECT ( STRTOSET(@.Region, CONSTRAINED) ) ON COLUMNS FROM [cube]) ...".

The report works fine using the Report Manager frontend. Now I want to pass this parameter directly within the query string:

https://servername/ReportServer?/PathTo/MyReport&rs:Command=Render&rs:Format=HTML4.0&Region=[foo].[bar 123].&[baz]

But I cannot get Reporting Services to accept the parameter instead of complaining about a missing parameter value. I've already tried quoting the braces, spaces, and the ampersand, putting the dimension in curly braces and/or quotes... No success.

How do I quote this parameter correctly?

I do this befor but so it was as follow

Report server URL(http://Machinename/reportserver/) + Reports Folder (MyReports/)+Reportname (My report) +"&Firstparametername"+Value+"&secondparametername"+Value

it will be like this

http://Machinename/reportserver/(MyReports/My repor&Firstparametername=Value1&secondparametername=Value

Thanks for your reply.

Normal query parameters work fine, I just can't pass OLAP parameters (dimensions like "[foo].[bar 123].&[baz]") this way. ReportServer won't accept them, I think it doesn't like the way I'm trying to quote them...

Thanks and best regards,
Thomas

Hi there!

It was indeed quoting related, I must have confused hex with decimal notation in my earlier attempts.

All you have to do is urlencode the parameter names and values. Here is how to quote correctly:

InputEncoded[%5B]%5D&%26spaces+ or%20

Or you let ASP.Net do the job:

1string encodedParam = HttpContext.Current.Server.UrlEncode(myParam);

So ...&Region=[foo].[bar 123].&[baz]... becomes...&Region=%5Bfoo%5D.%5Bbar+123%5D.%26%5Bbaz%5D...

If you want this parameter to have multiple values, just use it multiple times in your URL: ...&Region=%5Bfoo%5D.%5Bbar+123%5D.%26%5Bbaz%5D&Region=%5Bfoo%5D.%5Bbar+123%5D.%26%5Bheureka%5D...

HTH and best regards,
Thomas
