Learn about grouping delivery data in the Media Transparency Center.
When looking at Buy Data in the IO or Media buy level, the delivery data can sometimes be grouped under the 'Other' Entity.
This happens when the delivery data is relevant for a date range no IO is linked to.
To further inspect the matter and make sure this is indeed an IO date range matter, create a report, pivot table, or table widget with the following fields: Day, Media Buy Name/Key, IO key, IO start date, IO end date, and Impressions.
You get the following:
In this example, you can see that for the same media buy key, the data in some of the days is attributed to a real IO, and starting September 11, the data is attributed to 'Other'. Notice that the IO end date is September 10, therefore, this data is out of the IO's date range.
