DataSource.Error: OData: Unsupported query option encountered: $expand
What am I doing wrong? How do I solve it?

if you right click on the column you would like to expand, and select unpivot then you will be able to expand it

NetrelemoThanks @amitchandak,
I have seen those links already, but they are not helpful.
Maybe I should rephrase my question: How do I convert a column of data type records to a column of data type table. I'm not expecting a solution, since the problem is not actually inPowerQuery, but rather in the underlying data provider.
The PowerQuery function
= Table.ExpandRecordColumn(Filtered, "Time", {"TimeMonthOfTheYear"}, {"Time.TimeMonthOfTheYear"})would theoretically do the trick, but since the data provider bombs out, it won't work. So now I'm wondering if I must have some sort of custom function approach to read each record and extract this one field that I want from the record.
