Hello!
I've got several tables uploaded to PBI dataflows and further using them for a report.
The columns that are in decimal format are not coming out correctly in PBI Desktop:PBI Desktop
PBI Dataflows
Do we know what causes this to occur and how to possibly fix it?
Br,
Johannes
Solved! Go to Solution.
I'm experiencing the exact same problem. I use dataflows, power BI desktop and then I publish to power BI service.
I use Locale for import: Dutch (Belgium), in power BI desktop.
this makes dataflows unusable until fixed. ![]()
for more info see my post below:
@MatthewRoche is de product development team aware of this issue?
@tex628,
I am unable to reproduce this issue on my side. Have you changed the type of the columns in Dataflow to decimal number?Source excel file

My source is MSSQL Server. So that might be a factor. But this is the formatting settings: Dataflows
Dataflows
PBI Desktop
Previous image is taken with raw data from flows, no transformations
Any idea's?
@tex628,
What data type do you set for the column in SQL Server? Could you please the original sample data in SQL Server table? It seems that you store whole numbers as decimal number in SQL Server table.

Lydia
