## Mapping of phases to dates

Hello,

I have a table of actual hours submitted to system and I would like to map the phases according to a custom table.

Example of actual hours table:

 Resource Name Date Hours Resource1 5/1/2022 1 Resource1 6/30/2022 5 Resource2 6/30/2022 4

Example of phases table:

 Start End Phase 5/1/2022 6/15/2022 Phase1 6/16/2022 8/31/2022 Phase2

What is the most efficient approach to map these tables so in final I would see which hours belong under which phase?

Should I merge somehow the phases table to calendar table in power query? Or using DAX?

Please note that the table with actuals has 10,000+ rows, above is just a simplified example.

Thanks,

Majo

Here's a DAX solution. No relationship exists between ActualHours and Phases.

Calculated column in ActualHours:

``````Phase =
VAR vDate = ActualHours[Date]
VAR vTable =
FILTER ( Phases, vDate >= Phases[Start] && vDate <= Phases[End] )
VAR vResult =
MAXX ( vTable, Phases[Phase] )
RETURN
vResult``````

Hello,

as per my understanding, calculated columns are less effective than measures.

But in this case it is not possible because result is a string, or is it?

Thanks,

EDIT: Never mind, I got it quickly. 🙂

``````Actuals:=
VAR SumActuals = SUM(Actuals[Hours])
VAR vDate = MAX(Actuals[Date])
VAR vTable= FILTER ( Phases, vDate >= Phases[Start] && vDate <= Phases[End] )
VAR vResult = MAXX ( vTable, Phases[Phase] )
RETURN
CALCULATE(SumActuals,Phases[Phase]=vResult)``````
