Refreshing in PBI Service changes data significantly

[Anonymous]

Hello everybody,

I am having issues with one of my datasets. I did some minor changes on it for a report I wanted to build; afterwards I published the dataset. At first there was no problem, I built the report and published it - but when the dataset had refreshed in PBI Service, the data changed significantly: the report displays percentages, and some of those increased by a magnitude of 10^14 - but only some, not all of them. Others did apparently not change at all, and the rest changed by a magnitude of 10^1. My first thought was that there had to be issues with the data I am using; but, when I refresh the dataset locally (i.e. the .pbix on my laptop) and re-publish it, I get the correct values again. That is, until automatic refresh in PBI service has completed. And this is exactly what I do not understand: Where is the difference in whether the dataset is refreshed locally or via PBI Service? To my understanding there should be no difference at all. Has anybody experienced a similar issue and can help me out? I am totally clueless about this.

Thanks in advance,

Moritz

Hello @v-cherch-msft,

thank you for answering. I was able to resolve the problem by now: I did not format the column containing the data in the query editor. When loaded into the dataset, it was auto converted to a text value - I do not know why this did not cause problems in PBI Desktop as one would expect, but only after refreshing via Service; anyway, properly formatting the column resolved the issue.

I just came across this issue in a similar situation, was tearing my hair out for 2 days!

Knew it would be something simple like this. Thanks for solving.
