Treatment fails during initialization

• Check the error logs in the UI
• Verify database connection has required permissions (Anonymization connection requirements)
• Delete the failed treatment and create a new one

Some columns aren't being classified

• Test Data Manager only classifies common PII types by default
• Manually assign datasets to unclassified columns in the Anonymization tab
• Consider using custom classification rules if you have many similar columns

Primary key errors when running treatment

• Primary keys cannot be masked (see Columns that cannot be masked)
• Remove primary key columns from the treatment
• See Anonymization troubleshooting for more details

Treatment runs but data doesn't look right

• Check the dataset assignments in the Anonymization tab
• Verify determinism settings if you need consistent masking
• Review the Summary tab to ensure expected columns are being masked
