Expression.Error: The key did not match any rows in the table

[kcantor]

I have a data set that has refreshed successfully in the past. It was built 3 days ago and refreshed fine for two days. Now I cannot refresh it either on the desktop version or from services. The error reads Expression.Error: The key didn't match any rows int he table. Other tables return the error message Load was cancelled by an error in loading a previous table. I tried to delete the problematic table from the data set with plans to re add it later. When I deleted the problem table, a second table threw the same error. I removed it too and a third then erred.  It is a domino effect. All tables are failing one at a time. The tables, however, are fine. I can use them in other documents and in PowerPivot. any ideas?

A coworker updated her version and the gateway and is getting the same error. This was built in a group and resides in the group folder.

I also had this problem and the reason is that every time I download the raw data from salesforce, the worksheet is given a different name, so the worksheet name needs to be updated in each query under 'navigation'. I have only had this issue since importing xls files rather than csv's, so might just go back to csv's.

Thak you. It solved my problem but do you know why it happened in the first place?

Nothing changed - 1 day it worked - the next day refresh bombed with this message

The refresh preview approach did not resolve the issue for me.

I created new connections to the same data source and then used Advanced Edit to copy the new connection strings to my original tables.

Has Microsoft acknowledged this is a PowerBI Desktop issue ?

Anybody understand the root cause ?
