Hi,
So from time to time I get the following error. If I go to the power query and refresh the preview usually the problem goes away. 
Any ideas on why this happens and how to avoid?
Hi, @campelliann
Based on the above error message, I think you should modify the filter row step in the 'EM falta Beebole' query. This step refers to other queries or other steps, so that the correct data source cannot be directly accessed.
