Multiple conditions on MDX query - reporting-services

Question

I have the following MDX query:
WITH
member [Measures].[USD Sales YTD] as (
SUM( {[Invoice Date].[Calendar].[Month].&[201501]:[Invoice Date].[Calendar].[Month].&[201506]},[Measures].[USD Sales] ))
member [Measures].[USD Sales LY YTD] as (
SUM ( {[Invoice Date].[Calendar].[Month].&[201401]:[Invoice Date].[Calendar].[Month].&[201406]},[Measures].[USD Sales]))
member [Measures].[Unit Sales YTD] as (
SUM ( {[Invoice Date].[Calendar].[Month].&[201501]:[Invoice Date].[Calendar].[Month].&[201506]},[Measures].[Unit Sales]))
member [Measures].[Unit Sales LY YTD] as (
SUM ( {[Invoice Date].[Calendar].[Month].&[201401]:[Invoice Date].[Calendar].[Month].&[201406]},[Measures].[Unit Sales]))
SELECT
NON EMPTY { [Measures].[USD Sales YTD]
, [Measures].[USD Sales LY YTD]
, [Measures].[Unit Sales YTD]
, [Measures].[Unit Sales LY YTD]
} ON COLUMNS
, NON EMPTY {
(
[Invoice Date].[Calendar].[Month]
* [Customer].[Customer Name].[Customer Name]
* [Part].[Part #].[Part #]
* [Sales Rep].[Sales Reps].[Sales Rep]
) } DIMENSION PROPERTIES [Part].[Part #].[Part Desc], MEMBER_CAPTION, MEMBER_UNIQUE_NAME ON ROWS
FROM ( SELECT ( [Sales Rep].[Sales Reps].[Sales Rep].&[12]) ON COLUMNS
FROM ( SELECT ( [Invoice Date].[Calendar].[Month].&[201506]) ON COLUMNS
FROM [AlphaBI])
)
WHERE ( {[Part].[Sales Unit].&[B], [Part].[Sales Unit].&[M]})
It works fine. It's giving me the month, customer, product, salesman and Sales YTD, Sales LYTD, Units YTD and Units LYDT.
Recently, a user asked me to change the WHERE condition to say if it's Sales than use sales unit B & M (like now), BUT if it's Units, then just B. Do you know how I can do that? In SQL it would be pretty easy, but my MDX skills are a bit rusty. Any help would be appreciated.
Thanks,
Alex

Answer 1

Just add a small condition in your WHERE clause, just like in SQL using IIF
WHERE (
{
[Part].[Sales Unit].&[B],
IIF(#param = "sales", [Part].[Sales Unit].&[M], null)
}
)
This will select the members [Part].[Sales Unit].&[B] and [Part].[Sales Unit].&[M] if the parameter selected is "sales", otherwise selects only [Part].[Sales Unit].&[B]
If you want to go a step even further and add even one more level of check, like if "none" is selected, it should add Sales Unit "A", then use nested IIF statements like so -
IIF(#param = "sales", [Part].[Sales Unit].&[M], IIF(#param = "units", null, [Part].[Sales Unit].&[A])
Assuming no additional checks are required, the code should look like -
WITH
MEMBER [Measures].[USD Sales YTD] AS
SUM(
{
[Invoice Date].[Calendar].[Month].&[201501]
:
[Invoice Date].[Calendar].[Month].&[201506]
},
[Measures].[USD Sales]
)
MEMBER [Measures].[USD Sales LY YTD] AS
SUM (
{
[Invoice Date].[Calendar].[Month].&[201401]
:
[Invoice Date].[Calendar].[Month].&[201406]
},
[Measures].[USD Sales]
)
MEMBER [Measures].[Unit Sales YTD] AS
SUM (
{
[Invoice Date].[Calendar].[Month].&[201501]
:
[Invoice Date].[Calendar].[Month].&[201506]
},
[Measures].[Unit Sales]
)
MEMBER [Measures].[Unit Sales LY YTD] AS
SUM (
{
[Invoice Date].[Calendar].[Month].&[201401]
:
[Invoice Date].[Calendar].[Month].&[201406]
},
[Measures].[Unit Sales]
)
SELECT
NON EMPTY
{
[Measures].[USD Sales YTD],
[Measures].[USD Sales LY YTD],
[Measures].[Unit Sales YTD],
[Measures].[Unit Sales LY YTD]
} ON COLUMNS,
NON EMPTY
{
(
[Invoice Date].[Calendar].[Month] *
[Customer].[Customer Name].[Customer Name] *
[Part].[Part #].[Part #] *
[Sales Rep].[Sales Reps].[Sales Rep]
)
} DIMENSION PROPERTIES [Part].[Part #].[Part Desc], member_caption,
member_unique_name ON ROWS
FROM ( SELECT
(
[Sales Rep].[Sales Reps].[Sales Rep].&[12]
) ON COLUMNS
FROM ( SELECT
(
[Invoice Date].[Calendar].[Month].&[201506]
) ON COLUMNS
FROM [AlphaBI]) )
WHERE (
{
[Part].[Sales Unit].&[B],
IIF(#param = "sales", [Part].[Sales Unit].&[M], null)
}
)
EDIT 2
Does this help? I have moved the association with Sales Unit attribute to the definition of member instead of WHERE clause.
WITH
MEMBER [Measures].[USD Sales YTD] AS
SUM(
{
[Invoice Date].[Calendar].[Month].&[201501]
:
[Invoice Date].[Calendar].[Month].&[201506]
}
*
{
[Part].[Sales Unit].&[B],
[Part].[Sales Unit].&[M]
}
,
[Measures].[USD Sales]
)
MEMBER [Measures].[USD Sales LY YTD] AS
SUM (
{
[Invoice Date].[Calendar].[Month].&[201401]
:
[Invoice Date].[Calendar].[Month].&[201406]
}
*
{
[Part].[Sales Unit].&[B],
[Part].[Sales Unit].&[M]
}
,
[Measures].[USD Sales]
)
MEMBER [Measures].[Unit Sales YTD] AS
SUM (
{
[Invoice Date].[Calendar].[Month].&[201501]
:
[Invoice Date].[Calendar].[Month].&[201506]
}
*
{
[Part].[Sales Unit].&[B]
}
,
[Measures].[Unit Sales]
)
MEMBER [Measures].[Unit Sales LY YTD] AS
SUM (
{
[Invoice Date].[Calendar].[Month].&[201401]
:
[Invoice Date].[Calendar].[Month].&[201406]
}
*
{
[Part].[Sales Unit].&[B]
}
,
[Measures].[Unit Sales]
)
SELECT
NON EMPTY
{
[Measures].[USD Sales YTD],
[Measures].[USD Sales LY YTD],
[Measures].[Unit Sales YTD],
[Measures].[Unit Sales LY YTD]
} ON COLUMNS,
NON EMPTY
{
(
[Invoice Date].[Calendar].[Month] *
[Customer].[Customer Name].[Customer Name] *
[Part].[Part #].[Part #] *
[Sales Rep].[Sales Reps].[Sales Rep]
)
} DIMENSION PROPERTIES [Part].[Part #].[Part Desc], member_caption,
member_unique_name ON ROWS
FROM ( select {[Part].[Sales Unit].&[B], [Part].[Sales Unit].&[M]} FROM (
SELECT
(
[Sales Rep].[Sales Reps].[Sales Rep].&[12]
) ON COLUMNS
FROM ( SELECT
(
[Invoice Date].[Calendar].[Month].&[201506]
) ON COLUMNS
FROM [AlphaBI]) ) )

(I don't feed our mdx into RS so guessing a bit)
Can you add in a parameter into your report (I've called it #switch) which dynamically creates a set at the top of your script- this is then referenced in the WHERE clause:
WITH
set [whereSet] AS
strToSet(
iif(#switch = "Both",
"{[Part].[Sales Unit].&[B], [Part].[Sales Unit].&[M]}"
,"{[Part].[Sales Unit].&[B]}"
)
)
member [Measures].[USD Sales YTD] as (
SUM( {[Invoice Date].[Calendar].[Month].&[201501]:[Invoice Date].[Calendar].[Month].&[201506]},[Measures].[USD Sales] ))
member [Measures].[USD Sales LY YTD] as (
SUM ( {[Invoice Date].[Calendar].[Month].&[201401]:[Invoice Date].[Calendar].[Month].&[201406]},[Measures].[USD Sales]))
member [Measures].[Unit Sales YTD] as (
SUM ( {[Invoice Date].[Calendar].[Month].&[201501]:[Invoice Date].[Calendar].[Month].&[201506]},[Measures].[Unit Sales]))
member [Measures].[Unit Sales LY YTD] as (
SUM ( {[Invoice Date].[Calendar].[Month].&[201401]:[Invoice Date].[Calendar].[Month].&[201406]},[Measures].[Unit Sales]))
SELECT
...
...
WHERE [whereSet]
