I have come across an issue when importing paid search metrics from a data source. I followed the documentation and successfully imported a data source file containing Impressions, Clicks, Total Cost along with 4 dimensions (eVars) - Tracking Code, Campaign (7d), Campaign (30d) and Campaign (90d) and the date obviously. The eVars are exactly the same as the Tracking Code with only difference being the expiration time.
This is what I get in Workspace and it all checks out.
The issue arises when I try to add another Adobe Analytics metric such as Unique visitors etc. - I get no values at all. Same goes for breaking down the data by other dimensions such as CID (90d) PPC network which is in this case a classification eVar extracting only the network part from the entire cid code (tracking code). That only returns "unspecified" value.
However, without the data source metrics the classifications (all of them) are working just fine as are the Adobe Analytics metrics as you can see on the screenshot below.
Any help or ideas on this would be much appreciated as I really can't wrap my head around this. Especially the classification eVars as they are specifically set for dissecting the Campaign (90d) eVar cid code.
