Hello
Two questions on dimensions and columns.
Question 1: What's a good way to see what columns are available for which dimensions?
When trying to use AD_EXCHANGE_IMPRESSIONS column with MOBILE_APP_RESOLVED_ID dimension, I get COLUMNS_NOT_SUPPORTED_FOR_REQUESTED_DIMENSIONS.
Question 2:
Tried experimenting with other columns, such as AD_SERVER_IMPRESSIONS and have other results I'm unsure how to interpret. Now I see no data in the report for one account (but there is data for another).
In other words, say I have two accounts. Both accounts have data for AD_EXCHANGE_* dimensions (e.g., using AD_EXCHANGE_MOBILE_APP_NAME as dimension and AD_EXCHANGE_IMPRESSIONS as column).
But one has data when using, for instance MOBILE_APP_RESOLVED_ID dimension and AD_SERVER_IMPRESSIONS column, and another doesn't.
Any hints?
