Re: PBI Dataflows Folder data source & custom columns

How are you connecting to the OneDrive folder? I was not able to connect to my OneDrive folder and combine files like I can when I use a (local) folder data source. This article (https://docs.microsoft.com/en-us/power-bi/desktop-use-onedrive-business-links) also suggests that you have to connectto each individual file and then merge/append as required.

 

Could you share your queries so I can understand how you are connecting to OneDrive?

Re: PBI Dataflows Folder data source & custom columns

Blast from the past here - 

 

For loading all the files in a folder: I tried copying all of the advanced editor M code in a Dataflow blank query, but got the following error.  Pretty sure that's because the Sample Queries that are also produced when merging files, obviously aren't present. 

How did you get around that?

That's correct you'll need to copy in all the individual queries generated by Power BI when combining files from a Folder data source.

Re: PBI Dataflows Folder data source & custom columns

Yes. this is very tedious. I posted on the Ideas forum so that PQW automatically imports query dependencies, like happens when you copy/paste between desktop apps:
