how to sum values?

[saska10]

Hi everyone,

I'm using Power BI desktop working on a car reporting task, and have been struggling with the following problem for days. I'm quite new to Power BI and have very basic DAX knowledge.

Here are the tables (relevant columns):

REFUEL

Date	Time	Registration Number	Refuel (l)
2017.02.28	10:48	AAA001	51,11
2017.03.03	07:39	AAA001	40,18
2017.03.04	10:03	AAA001	46,46
2017.03.09	09:46	AAA001	36,45
2017.03.14	18:35	AAA001	37,09
2017.03.16	19:53	AAA001	52,15
2017.03.21	09:07	AAA001	31,62
2017.03.23	07:48	AAA001	45,26
2017.03.27	08:48	AAA001	48,87
2017.04.02	16:14	AAA001	49,06

Distance:

Date	Time	Registration Number	Distance(km)
2017.02.28		AAA001	120
2017.02.29		AAA001	160
2017.03.03		AAA001	230
2017.03.04		AAA001	320
2017.03.08		AAA001	190
2017.03.09		AAA001	270
2017.03.12		AAA001	370
2017.03.14		AAA001	400
2016.03.16		AAA001	280
2017.03.20		AAA001	340
2017.03.21		AAA001	350
2017.03.22		AAA001	230
2017.03.23		AAA001	250
2017.03.25		AAA001	410
2017.03.27		AAA001	370
2017.04.01		AAA001	390
2017.04.02		AAA001	240

I'd like to sum the distance in this way:

refueling on the closest day to the last day of the month --> its the firtst day i want to sum (02.28 - 120 km)

to the refueling on the closest day to the day of the next month --> its the last day I want to sum (04.02 - 240 km)

Could anyone please give me any hint how to achieve this?

Thanks!

Hi @saska10,

It's difficult to reproduce your scenario based on your description, please list your expected result from the sample data sample. So that we can provide the solution which is close to your requirement. Thanks for understanding.

Hi @v-huizhn-msft,

I want a result table like this:

Date	Registration Number	Distance
2017.02.28	AAA001	120
2017.02.29	AAA001	160
2017.03.03	AAA001	230
2017.03.04	AAA001	320
2017.03.08	AAA001	190
2017.03.09	AAA001	270
2017.03.12	AAA001	370
2017.03.14	AAA001	400
2016.03.16	AAA001	280
2017.03.20	AAA001	340
2017.03.21	AAA001	350
2017.03.22	AAA001	230
2017.03.23	AAA001	250
2017.03.25	AAA001	410
2017.03.27	AAA001	370
2017.04.01	AAA001	390
2017.04.02	AAA001	240

All in all, the most important thing that the result table containts: from the day of refueling closest to the new month till the next new month's closest day of refueling.

Thank you for your help!

Hi @saska10,

For this result table, you can click New table under Modeling on home page, type the following formula.

result-table=SELECTCOLUMNS(Distance,"Date",Distance[Date],"Registration Number",Distance[Registration Number],"Distiance",Distance[Distance])

Can you explain why 3.27 is not the day that you want instead of 4.02?

I'm guessing that you would need to have a central date table involved here and relate both refuel and distance tables to it. In theory, you could then create a measure that uses ENDOFMONTH in a context that will achieve what you want.
