CSV Files - total size limit

[Anonymous]

Hello

I have 3 CSV files (180mo +3.4go + 3.4go) which are merged on PowerBi Desktop (I have a premium account).

I noticed that all calculations were wrong since the total space storage for those files passed over 6go.

Each CSV file contains financial data per year. For Example, in 2017, I should have a 101k€ turnover. PBI shows me 115k€ if I merge those 3 csv files.

If I create a specific PBI with one CSV file, I do have the correct figures.

The most ashtonishing is that I don't have any error message when I do import the data.

Any idea please ? Is it linked to my Ram Memory or my processor ?

Hi @Anonymous,

How did you combine the three tables? Merge queries or append queries? If they were merged, which option did you choose, inner join, lefter outer join or any other?

@v-yulgu-msft I combined them with append. In query editor, I used table.combine().

FYI, the total size of my pbix is around 400mo. I don't understand if the file size limit explained in PBI tutorials concerns the source files (csv) or the pbix file. Could it be the problem ?

So, is the 101k€ turnover number some calculation that you are doing? Where does that number come from?

The 101k€ calculated is done with access.
I found this result too wkth powerbi desktop if I import one csv file which contains 2017's data.

I'm so desperate Greg_Deckler. Any suggestion would be appreciated.
