Simple sql to mdx query using the max fn

Question

I'm using the MDX Max fn to get the max of a certain value but now I want get max for a certain pair of values and not all, how could i write this in mdx as a calculation?
More details: For a certain pair of status and substatus (status=1, substatus=1) from a trans dimension table i want to get the max insertionid (attribute in trans measure table). How would you guys suggest I go about this?
I'm new to mdx and I'm converting a whole sql statement to a measure not to include it as a named query for performance concerns!
If needed this is the sql query im converting:
SELECT TOP (1) InsertionDT
FROM dbo.TransTasksFFMS_GVT AS TSI
WHERE (TaskCode = T.TaskCode) AND (TaskStatus = 1) AND (TaskSubStatus = 1)
ORDER BY InsertionDT) AS RegistrationTimeWithoutConversion
Another way to think of this is how to apply a certain measure only on certain values and not all values in the browser.

Hi Junior,
According to your description, you want to get the max value by using MDX query, right? Since no know your cube detail information, we cannot convert this T-SQL to MDX query. Here is a sample MDX query for your reference. The query below returns the Sale
Amount measure and the MaxValue calculated member.  The MaxValue calculated member takes the maximum value for members of the Fiscal Year level in the Fiscal hierarchy of the Date dimension.
WITH
MEMBER [Measures].[MaxValue] AS
MAX([Date].[Fiscal].[Fiscal Year].Members, [Measures].[Sales Amount])
SELECT
{[Measures].[Sales Amount],[Measures].[MaxValue]} ON COLUMNS,
{[Date].[Fiscal].[Fiscal Year].Members} ON ROWS
FROM
[Adventure Works]
Reference:Max (MDX)
