Ordering MDX query wih Named set gives error, "The CURRENT function cannot be invoked in this context ".

Question

Hi,
I have following Query 
WITH SET [Union name set test] AS {[Union].[Union Name].&[2],[Union].[Union Name].&[3],
[Union].[Union Name].&[4],[Union].[Union Name].&[5],[Union].[Union Name].&[6]}
SELECT {[Measures].[Emp Count]} ON 0,  
{ORDER({[Union].[Union City].[Union City]*[Union name set test]}, 
[Union name set test].CURRENTMEMBER.MEMBERVALUE, BASC)} ON 1 FROM [Federations];
when i run this query from code as well as SSMS i get following error...
The CURRENT function cannot be invoked in this context because the 'Union name set test' set is not in the scope.
Please help me for this ....

Hi Mihirhp,
Base on my research, there are some similar issues and the resault turn out that the Tabular model engine can’t associate .currentmember with a set. The workaround  is to use .current in the MDX query. Please try the query below.
WITH SET [Union name set test] AS {[Union].[Union Name].&[2],[Union].[Union Name].&[3],
[Union].[Union Name].&[4],[Union].[Union Name].&[5],[Union].[Union Name].&[6]}
SELECT {[Measures].[Emp Count]} ON 0,
{ORDER({[Union].[Union City].[Union City]*[Union name set test]},
[Union name set test].CURRENT.MEMBERVALUE, BASC)} ON 1 FROM [Federations];
Hope this helps.
