Hi @mahsy ，

Please try this measure. And set the filters as shown in the figure.

Measure = COUNTROWS('Table') - COUNTROWS(SUMMARIZE('Table','Table'[Course],'Table'[PR],'Table'[Date]))

Attached PBIX file for reference.

@mahsy ,

create a calculated column like the below and put that column in the X-axis (values) or Y-axis (values), then set the aggregation as count.

Earlier = COUNTX(filter(Table_count,EARLIER(Table_count[Course])=Table_count[Course] && EARLIER(Table_count[PR])=Table_count[PR] &&EARLIER(Table_count[Date])=Table_count[Date]),Table_count[Course])

Thanks,

@mahsy ,

try this in measure,

cal = CALCULATE(COUNT(Table_count[Course]),FILTER(ALL(Table_count),
COUNTX(filter(Table_count,
EARLIER(Table_count[Course])=Table_count[Course] && 
EARLIER(Table_count[PR])=Table_count[PR] &&
EARLIER(Table_count[Date])=Table_count[Date]),
Table_count[Course])))

Thanks,
