Hi @abodqm ,

Suppose we have:

Please try like:

Measure = 
VAR _cur_month_number = SELECTEDVALUE('Table'[Month])
VAR _centers_before = CALCULATETABLE(VALUES('Table'[centers]),'Table'[Month]<_cur_month_number)
VAR _result = IF(ISBLANK(_cur_month_number),"Please choose a month",CALCULATE(DISTINCTCOUNT('Table'[centers]),NOT 'Table'[centers] IN _centers_before))
RETURN
_result

Output:

check the pbix file.
