What should I do if my data upload fails validation?

If your data upload fails validation, follow these steps:

1. Review Error Messages: The system will display specific error messages indicating which rows or columns have issues

2. Common Issues:

   • Missing required columns (CMMI ID, measurement values, etc.)
   • Invalid CMMI IDs (participant not found in database)
   • Incorrect date formats (use YYYY-MM-DD)
   • Duplicate entries
   • Values outside expected ranges

3. Fix Your Data: Download your original file, correct the errors, and re-upload

4. Use the Template: Always start with the official template from the "Download Example" button to ensure correct formatting

5. Contact Support: If you continue to have issues, contact the CMMI-DCC team with your error messages and data file
