Community ChampionExpression.Error: The key did not match any rows in the table
Ran into this issue myself within the Power BI Desktop and was able to resolve the issue through the following:
- Select Edit Queries from the menu to open the Query Editor
- Use the left hand menu to select one of the queries having the issue (will have the triangular warning sign)
- On the applied steps menu at the right select the source step.
- In the top menu bar, select Refresh Preview.
In my case there were several queries having this same issues and the steps above resolved each of them.
Hope this helps -
Here's what worked for me:
- Have your replacement source file (e.g. excel file) ready to go. Make sure the file name and sheet names are the same.
- Then in PBI, in the Fields panel, right-click on the troublesome field. Delete it. The graph it populates will be replaced by a placehoulder saying "Something's wrong with one or more fields. Fix This". DON'T DO ANYTHING to the graph at this point.
- Instead, imediately click on Get Data. Select the new file and in a moment or two your graph should re-populate with the new data, and even retain the original formatting (e.g. colors, etc.). Hope this works for you.
I ran into this error and learned that the navigation step in the query was referring to a SQL table and that the table name was case significant. I had changed the database table from "sales" to "Sales" and ran into the thread title error both from PowerBI on my desktop and PowerBI web service. I capitalized the table name in the navigation step and everything went back to working as it previously was. Different cause, but wanted to share my experience and fix.
