MDX: I need only those highlighted records - ssas

Question

I need only those highlighted records.
SELECT
[Measures].[Assessment Patients Detail] ON COLUMNS,
NON EMPTY([DimAssessment].[Assessment Text].&[Employee Wellness HRA],
[DimAssessment].[Question Text].&[Do you use tobacco products?],
[DimPatient].[Patient Key].[Patient Key],
Generate(
[DimAssessment].[Answer Text].[Answer Text].MEMBERS
,[DimAssessment].[Answer Text].CURRENTMEMBER
*TAIL(
NonEmpty(
[DimDate].[Full Date Alternate Key].[Full Date Alternate Key].MEMBERS
,[DimAssessment].[Answer Text].CURRENTMEMBER
)
,[DimAssessment].[Question Text].&[Do you use tobacco products?]
)
)
)ON ROWS
FROM
[Care];

Answer 1

This probably isn't the answer as I've tried to help with this before but the following is a little mysterious:
The second argument of the function Tail is usually an integer e.g. 2 or 3 which means you would like the last 2, or last 3, members from the set specified in first arg of Tail.
I prefer to use cross-join rather than a tuple for members on rows but I don't think this will give you the rows you require:
SELECT
[Measures].[Assessment Patients Detail] ON COLUMNS,
NON EMPTY
{[DimAssessment].[Assessment Text].&[Employee Wellness HRA]}
*{[DimAssessment].[Question Text].&[Do you use tobacco products?]}
*[DimPatient].[Patient Key].[Patient Key].members
*Generate(
[DimAssessment].[Answer Text].[Answer Text].MEMBERS
,[DimAssessment].[Answer Text].CURRENTMEMBER
*TAIL(
NonEmpty(
[DimDate].[Full Date Alternate Key].[Full Date Alternate Key].MEMBERS
,[DimAssessment].[Answer Text].CURRENTMEMBER
)
,1 //[DimAssessment].[Question Text].&[Do you use tobacco products?]
)
)
ON ROWS
FROM
[Care];
We will need to move more of the logic inside the generate.
First try the following to see if it returns two correct columns?
SELECT
[Measures].[Assessment Patients Detail] ON COLUMNS,
NON EMPTY
Generate(
[DimPatient].[Patient Key].[Patient Key].MEMBERS
,[DimPatient].[Patient Key].CURRENTMEMBER
*TAIL(
NonEmpty(
[DimDate].[Full Date Alternate Key].[Full Date Alternate Key].MEMBERS
,[DimPatient].[Patient Key].CURRENTMEMBER
)
,1
)
ON ROWS
FROM
[Care];
