Odd requirements when using Adwords data source
When creating a table in data studio with Adwords as the data source, multiple dimensions are sometimes required for the table to work. When attempting to view impression share by Keyword, for instance, data studio gives an error that says the 'Ad Group ID + Keyword ID' dimension is required. The table will load once that extra dimension is added, but this extra column is not useful in most cases and it is taking up the same amount of space as 2 columns. If we could hide the extra column it wouldn't be an issue, but that does not seem to be an oprion. The requirement seems to appear for most or maybe all calculated type metrics, like CTR and conversion rate.
Is this normal or is this problem unique to my account? If this is a bug or something, does anyone have a fix?
