Ken wants to generate conversion reports that use different attribution models than the Primary model on the advertiser level.What nextstep can he take to achieve this?

The correct answer is to select a different attribution model for reporting in the reporting dashboard. Campaign Manager 360 (CM360) allows you to choose various attribution models (e.g., Last Click, First Click, Linear, Time Decay, Position Based) directly within the reporting interface when generating a report. This flexibility enables Ken to analyze conversions using different perspectives without altering the advertiser's primary attribution settings. Deleting the primary attribution model is incorrect because it would remove the default attribution logic for the advertiser, potentially impacting other reports and analyses. Adjusting the primary model account attribution settings first is also incorrect because Ken specifically wants to report on different models, not change the default attribution for the entire account. The reporting dashboard provides the necessary functionality for ad-hoc attribution model analysis.
