What happens if I have 20 report filters?

Salesforce reports support a maximum of 20 filters. Exceeding this limit will result in errors or process failures when interacting with the report programmatically. Our system adds a filter to your Salesforce report during processing. If your report already has 20 filters, adding our filter exceeds the limit, causing the process to fail. To avoid this issue limit the number of filters in your report to 19 or fewer. If that is not possible, consider using SOQL instead.
