Campaign Report returns more data than account performance report

[Thu Nguyen]

We're trying to query data from an account that has App Install Campaigns. Starting form 

The account has these two campaigns: 

Starting on 2017-02-10, when we use the campaign performance report, we receive more data than account performance report (for the same metrics).

May we check why? I can provide more details & cid in private message

Hi Thu,

The Campaign Performance Report is aggregated at the campaign level while the Account Performance Report is aggregated at the account level which is why comparing data between these 2 reports would possibly yield discrepancies.

To help us identify the data discrepancies you are pertaining to, could you send to us privately  the complete report definition used for both reports and your clientCustomerId and specify which data are you pertaining to that are inconsistent between the 2 reports.

Best regards,

Peter
