If you normally have an error when you try to update, or refresh a query, the system shows you what the error is.
For examples duplicates, of errors in the file you have imported.
However this time I have an error, and when you click on the 'show error', the table I get is empty.
I will attach views:
1) view of the original error
2)after I click view view error, this is the screen I get
All the data that is imported in the other tables worked, this table is a combined table of all above years together.
ex: = Table.Combine({#"2013", #"2014", #"2015", #"2016", #"2017"})
There was no error first, than we updated some data in the sources, all was refreshed without errors exept this error in the combined table called 2013-2017
