Calculated Column DAX is not giving the correct result.

[Anonymous]

Hi Experts

See expected result in the table below with light blue header. Need a cacalated column measure to give the max ACTDate if all the Child TaskID and WorkORder ID's have a date. If they have no ACTDate as shown in the first image then return back no max date..

The following calculated column which was done by a Experts on this site give the same same dates as shown in the second image with Blue Headers. SHOULD BE THE MAX DATE as shown above 12.04.2022

calculated column = if([POC] ="Parent" , blank(), maxx(filter(Table, [TAsk id] =earlier([Task id]) && [Workitem id] =earlier([Workitem id]) ), [Act Date])

Hi @Anonymous ,

You can create a calculated column as below to get it, please find the details in the attachment.

MaxDate =
VAR _count =
    CALCULATE (
        COUNT ( 'Table'[WorkOrderID] ),
        FILTER (
            'Table',
            'Table'[TaskID] = EARLIER ( 'Table'[TaskID] )
                && 'Table'[POC] = "Child"
        )
    )
VAR _count2 =
    CALCULATE (
        COUNT ( 'Table'[ACT Date] ),
        FILTER (
            'Table',
            'Table'[TaskID] = EARLIER ( 'Table'[TaskID] )
                && 'Table'[POC] = "Child"
                && 'Table'[ACT Date] <> BLANK ()
        )
    )
VAR _maxdate =
    CALCULATE (
        MAX ( 'Table'[ACT Date] ),
        FILTER (
            'Table',
            'Table'[TaskID] = EARLIER ( 'Table'[TaskID] )
                && 'Table'[POC] = "Child"
        )
    )
RETURN
    IF (
        ISBLANK ( _count2 ),
        "No Max",
        IF (
            'Table'[POC] = "Child"
                && _count = _count2,
            FORMAT ( _maxdate, "dd/mm/yyyy" )
        )
    )

If the above one can't help you, could you please provide more raw data in your tables (exclude sensitive data) with Text format, your column chart field settings and your expected result with backend logic and special examples? It would be helpful to find out the solution.
