Compare periods of data uploads (not necesarrily dates)

Anonymous — Tue, 15 Jun 2021 14:34:28 GMT

Hi everybody!

I am working on a report and I present the amount of money spend per period using this graph and the table underlyint this graph:

This is pretty straigthforward, but i am looking for a way to only visualize the amount of money spend per period instead of the cumulative of everything. As a quick solution i made seperate measures, where i manually subtracked Gebbedrag2 - Gebbedrag1 etc. The results are shown the following table.

However, it is difficult to make a nice visual with this and it will take manual work everytime i update this report.

Does somebody know the right formulas to get to this point, without having to make new measures everytime i upload something? Underneath i posted a table with a simplified version of the data i use.

index	date created	post	geboekt bedrag
1	7-1-2021	material	2510841
1	7-1-2021	staff	6528437
1	7-1-2021	overhead	131079
1	7-1-2021	food	35334
2	29-1-2021	material	2543553
2	29-1-2021	staff	6528437
2	29-1-2021	overhead	131079
2	29-1-2021	food	35334
3	8-3-2021	material	2596334
3	8-3-2021	staff	6528437
3	8-3-2021	overhead	137673
3	8-3-2021	food	35334
4	7-4-2021	material	2655314
4	7-4-2021	staff	7738437
4	7-4-2021	overhead	143647
4	7-4-2021	food	35334

Thanks!

Hi Anonymous -

Unless I'm misunderstanding the question, you may just be over thinking it. If you use Date Created as the column, Post as the rows, and SUM(geboekt bedrag) as the values it won't accumulate the sums over the entire table.

If you're meaning something else, please expand on what you are trying to accomplish.

Hope this helps

Hi Dedelman_clng,

Thanks for your reply. Maybe i was not clear enough in my explanation. I see your point, however, in this case i am only interested in the difference in the amount of money (Geboekt Bedrag) between every period (date created). Using "date created as column gives me a perfect overview on the total amount of "geboekt bedrag" eacht period, but how much more money is spend compared to the previous period.

Now i make seperate calculations like:

Calculate(table1''[geboekte kosten]) , 'table1'[index] = "2") - Calculate(table1''[geboekte kosten]) , 'table1'[index] = "1")

i did this for each following period, but i would like to find a way how i can automatically calculate the added amount to the column "geboekte kosten" for each period.

Does this make it more clear?

Hi Anonymous -

Here is a new column getting the value from the previous period, and then a measure to calculate (and display the difference.

PrevPd = VAR __Idx = [index] VAR __Post = [post] RETURN LOOKUPVALUE ( Geboekt[geboekt bedrag], Geboekt[index], __Idx - 1, Geboekt[post], __Post )

Delta = IF ( ISBLANK ( SUM ( Geboekt[PrevPd] ) ), BLANK (), SUM ( Geboekt[geboekt bedrag] ) - SUM ( Geboekt[PrevPd] ) )

Hope this helps
