count with filter
Dear All, I would like to count id if id date >= 01/07/2020 for both channel. The returned result will be 1 which is id 4. How can I write the measure column for this please help. Thanks
it's quite tricky. You should write a measure, not a column. The principle in DAX is "filter first, evaluate second". So you could try this (I haven't tested it).
= CALCULATE ( SUMX ( values(tablename[id]), IF ( calculate(countrows ( tablename[id] )) > 1, 1 ) ), FILTER ( tablename, tablename[date] >= DATE ( 2020, 7, 1 ) ) )

Actually I missed a point in my question that some id has only one channel also I need to check on. For examble below table ,if id has two channles both has to be greater than 01/07/2020 and if only one channel then it has to be greater than 01/07/2020. So for below table it should return 2 which ids 2 and 4. Please help. Thank you

= SUMX ( VALUES ( Table[id] ), VAR countOfChannels = CALCULATE ( DISTINCTCOUNT ( Table[channel] ) ) VAR countAfterDate = CALCULATE ( COUNTROWS ( FILTER ( Table, [date] > DATE ( 2020, 7, 1 ) ) ) ) RETURN IF ( countOfChannels = countAfterDate, 1 ) )Actually I am getting an error Thanks
