Hi

I have a scenario unable to do this scenario.  The requirement is client has source data looks in attachments here .

STAFF ID	Sortkey	STAFF_Employment_Type
1	1	PERMANENT
1	2	PERMANENT
1	3	PERMANENT
1	4	PERMANENT
1	5	PERMANENT
1	6	PERMANENT
2	1	PERMANENT
2	2	PERMANENT
2	3	PERMANENT
2	4	PERMANENT
2	5	PERMANENT
3	1	CONTRACT
3	2	CONTRACT
3	3	CONTRACT

If client writing Query on the database like below :-

select

EMPLOYMNT_TYPE_ID,

count(staff_id)

from

FACT_STF_DEMOGRPHCS s2

WHERE

( RS_DATE_ID=0 OR RS_DATE_ID>20151115)

AND

KEY_FIELD = (SELECT MAX(KEY_FIELD)FROM FACT_STF_DEMOGRPHCS WHERE staff_id = s2.staff_id)

GROUP BY   EMPLOYMNT_TYPE_ID ;

Client able to get result like below:

Staff ewmployment type     count(Staff_id)

contract                              72

Perminent                           182

Asper qlickview expresion i have written code as below:

=Count({<
	Year = {"<=$(vMaxYr)"},
	Month=,
	Quarter=,
	YYYYMM = {'<=$(vMaxYYYYMM)'},
	RS_YYYYMM = {'>=$(=Max(YYYYMM))'},
	[(h)Staff Employment Type ID] = {'=Max([(h)Staff Employment Type ID])'},
	[(h)Sort Key]= {'=$(vMaxSortkey)'},
	STF_DEMOGRPHCS_FLAG={'Y'}
	>}

   DISTINCT [(h)Staff ID])

Result i am  getting is

Staff ewmployment type     count(Staff_id)

contract                              85
