If you're experiencing a "failed to update waterfall" error, here's how to resolve it: 1. First, check if you have sufficient API credits with your data providers, as this is a common cause of waterfall failures.
2. To restart the process:
• Go to your first waterfall column
• Use the "Run all rows that haven't run or have errors" option
• This will only process the failed entries without duplicating successful ones
3. If you're setting up a new waterfall, ensure you have:
• Properly configured the waterfall sequence
• Entered all required data inputs
• Set up the correct output configurations
