### Answer Based on the available sources, I can see that post-call analysis data is configured through the

post_call_analysis_data

field when creating or updating an agent [(1) ]() [(2) ]() [(3) ]() . However, the specific error you're encountering about filtering in Call History isn't directly addressed in the documentation. A few things to check: 1. **Ensure your agent has post-call analysis configured**: The

post_call_analysis_data

field should contain your custom analysis variables [(1) ]() [(3) ]() 2. **Verify calls have been analyzed**: Post-call analysis data is only available after calls end and the analysis completes. The data appears in the

call_analyzed

webhook event [(4) ]() 3. **Check if you're using the correct agent**: Make sure you're filtering Call History for the specific agent that has the post-call analysis fields configured 4. **Recent platform updates**: According to the changelog, there have been improvements to Call History including custom attributes and column arrangement [(5) ]() . The filtering functionality may require that calls have already been completed and analyzed with your current configuration. If the issue persists after verifying these points, I'd recommend checking the [Documentation]() or reaching out to a [certified Retell partner]() for assistance with this specific dashboard filtering issue.
