Error

"Community Connector Error: Invalid Combination of Metrics and Dimensions Report Configuration Issue"

This error appears as a popup message in affected reports using Power My Analytics' Google Ads data connector. The error may appear in reports in Looker Studio, Google Sheets, and other reporting services and data destinations.

Cause

This error occurs due to a limitation in the Google Ads API that restricts which metrics can be combined with conversion action dimensions in a single report or chart element in a report. 

1. The error appears when a report or chart contains conversion action field dimensions combined with incompatible metrics, such as cost metrics.
   
2. Google's API only allows conversion action dimensions to be paired with specific conversion-related metrics.
   

Conversion Dimensions

1. Conversion Action
2. Conversion Category

Conversion Metrics

1. All Conversions
2. All Conversions Value
3. Conversions
4. Conversions By Conversion Date
5. Conversions Value
6. Conversions Value By Conversion Date
7. Cross Device Conversions
8. Current Model Attributed Conversions
9. Current Model Attributed Conversions Value

Solution

1. Open your report containing the Google Ads data source that's producing the error.
2. Identify the problematic reports or chart elements:
   
1. Look for reports or charts using both conversion action dimensions (Conversion Action or Conversion Category) and incompatible metrics, such as cost metrics
3. Modify the affected reports or charts:
   
1. Review both the dimensions and metrics, and remove either the conversion dimensions or the incompatible metrics
   
4. Repeat this process for all affected reports or chart elements.
   

Verify the fix by refreshing your report and confirming the error no longer appears.

Best Practices

• When creating new reports, consciously choose between conversion action dimensions or other metric types such as cost metrics, not both.
• Consider creating separate reports: one for conversion action analysis and one for cost/performance analysis.
