MDX Query - How to replace null with 0 in crossjoin - ssas

Question

I need to replace nulls with 0 in a crossjoin result of a mdx query.
This is my query:
WITH
MEMBER [Measures].[X] AS
([Indicador].[Indicador Descrição].&[X],[Measures].[MONTANTE])
MEMBER [Measures].[Y] AS
([Indicador].[Indicador Descrição].&[Y],[Measures].[MONTANTE])
SELECT
NON EMPTY {[Measures].[X],[Measures].[Y]} ON COLUMNS,
NON EMPTY{[Classificador Orgânico].[A].children*
[Programas e Medidas].[A].children*
[Classificador Económico Despesa].[A].children*
[Classificador Económico Despesa].[B].children*
[Classificador Económico Despesa].[C].children*
[Classificador Económico Despesa Rubricas].[A].children*
[Classificador Económico Despesa Rubricas].[B].children*
[Fonte de Financiamento].[A].children} ON ROWS
FROM [Cube]
WHERE ([Calendar].[Year].&[2018],[Calendar].[Month].&[04])
I already try to use coalesceempty in the calculated members but replaces all the nulls before the NonEmptyCrossjoin (the query doesn't even answer).
The ideal solution is to replace nulls only after the NonEmptyCrossjoin .What is the proper way to achieve that?
Thanks!

Answer 1

Can you try with:
WITH
MEMBER [Measures].[X] AS
([Indicador].[Indicador Descrição].&[X],[Measures].[MONTANTE]), FORMAT_STRING = '#,##0.00;-#,##0.00;;0'
MEMBER [Measures].[Y] AS
([Indicador].[Indicador Descrição].&[Y],[Measures].[MONTANTE]), FORMAT_STRING = '#,##0.00;-#,##0.00;;0'
SELECT
NON EMPTY {[Measures].[X],[Measures].[Y]} ON COLUMNS,
NON EMPTY{[Classificador Orgânico].[A].children*
[Programas e Medidas].[A].children*
[Classificador Económico Despesa].[A].children*
[Classificador Económico Despesa].[B].children*
[Classificador Económico Despesa].[C].children*
[Classificador Económico Despesa Rubricas].[A].children*
[Classificador Económico Despesa Rubricas].[B].children*
[Fonte de Financiamento].[A].children} ON ROWS
FROM [Cube]
WHERE ([Calendar].[Year].&[2018],[Calendar].[Month].&[04])
I have just added FORMAT_STRING. The first argument is how positive values should be formatted, the second is how negative values should be formatted, the third argument is how 0 values should be formatted, and the fourth argument is how NULL should be formatted - display a 0 instead.
The problem with using CoalesceEmpty or isEmpty like this
IIF(ISEMPTY(([Indicador].[Indicador Descrição].&[X],[Measures].[MONTANTE])) , 0 , ([Indicador].[Indicador Descrição].&[X],[Measures].[MONTANTE]))
is that you are filling empty cells in the cube with zeros, so result set of cross join will be huge, and query probably won't finish at all.
