Duration of the chained workleaves

[henkka]

Hi,

I have a table where there is id. next chained id Start date, End date.

What I'm trying to achieve is to calculate the total duration of the work leaves but I'm not able to come up with the solution how the "edge case" is recognized that it is the last workleave that is part of the whole chain and the bolded "False" should also be True 

This is my best effor (calculated column

IsLastWorkleave =

VAR current_id = FactWorkleaves[Workleave.id]

VAR next_id = FactWorkleaves[Nextchainedworkleave.id]

VAR last_id =

    IF(

        next_id = BLANK(),

        current_id,

        CALCULATE(

            MAX(FactWorkleaves[Workleave.id]),

            FILTER(

                ALL(FactWorkleaves),

                FactWorkleaves[Workleave.id] <> current_id &&

                FactWorkleaves[Workleave.id] > current_id &&

                FactWorkleaves[Workleave.id] <= next_id &&

                FactWorkleaves[Nextchainedworkleave.id] <> BLANK() &&

                FactWorkleaves[Nextchainedworkleave.id] <> current_id

            )

        )

    )

RETURN

    current_id = last_id

Hi here is a table with expected end result Workleaves table

Hi here it is another try Table 

[henkka]

I got a bit forward with this and got the dax to calculate the total duration of the chained work leaves

ChainedWorkLeavesDuration =

VAR CurrentWorkLeaveId = FactWorkleaves[Workleave.id]

VAR ChainedWorkLeaves =

FILTER ( 

FactWorkleaves , PATHCONTAINS ( FactWorkleaves[path] , CurrentWorkLeaveId )

           )

RETURN  

SUMX ( ChainedWorkLeaves , FactWorkleaves[Duration] )

But still have a problem how to calculate the work leave total duration correctly only once by workleave

Now the table calculates like this

Workleave.id	Previouschainedworkleave.id	path	Duration	Total duration
111		111	1	1
222	111	111 | 222	1	2
333	222	111|222|333	1	3
444		444	1	1
555		555	1	1

but the correct end result would be

Workleave.id	Previouschainedworkleave.id	path	Duration	Total duration
111		111	1	3
222	111	111 | 222	1	0
333	222	111|222|333	1	0
444		444	1	1
555		555	1	1
