Report Builder 3.0 Dataset Parameter

Question

Hi,

I need to pass a set of data as a parameter to my dataset, because all my filters are gathered outside the report.

I wish to pass a parameter like this:

{[CLIENTE].[SEGUIMENTOS].[SEGUIMENTO].&[DISTRIBUIDORES / ATACADOS]},{[VENDEDOR].[SUPERVISORES].[SUPERVISOR].&[GERENTE DE VENDAS]}

So I could use in the Where() function in my MDX query.

I tested the MDX with this parameter and it works.

So I added a @Filtros parameter to my dataset query, but It throws an error saying that it was expecting a tuple set and instead recieved a number or a string.

My Query:

 SELECT 
	NON EMPTY { [Measures].[FAT] } ON COLUMNS, 
	NON EMPTY { 
		([PRODUTO].[CLASSES].[PRODUTO].ALLMEMBERS * [Time].[Time].[Quarter].ALLMEMBERS ) 
	} 
	DIMENSION PROPERTIES MEMBER_CAPTION, MEMBER_UNIQUE_NAME ON ROWS 
FROM 
	[SCA] 

WHERE(@Filtros)

CELL PROPERTIES 
	VALUE, BACK_COLOR, FORE_COLOR, FORMATTED_VALUE, FORMAT_STRING, FONT_NAME, FONT_SIZE, FONT_FLAGS

Thank you.
