Hello Community
Problem:
Currently, there is no way to preview the output of a Dataflow without executing it entirely. This leads to several issues:
- Risk of overwriting existing data if the logic is incorrect
- Long execution times, especially without perimeter filters
- Difficulty testing or validating transformations safely during development
💡 Suggestion:
Introduce a "Preview Mode" button for each Dataflow step (similar to what exists in Layouts), which:
- Runs the step in simulation mode without writing to the target cube
- Displays the expected output temporarily
- Helps developers verify logic safely before actual execution
🎯 Benefits:
- Safer development and testing
- Faster debugging
- Reduced risk of data loss or errors
