RVR-SYNP-319

Issue Summary
- The error code RVR-SYNP-319 indicates a failure in synchronizing columns between Data Integration and an Azure Synapse data source. This issue occurs when Data Integration is unable to find expected column mappings, leading to a mismatch error. This is often due to schema changes in the source or target database that Data Integration has not been updated to align with.
Action Steps:
- Check Schema Compatibility:
  - Ensure that the table schemas in both your source (Azure Synapse) and Data Integration are synchronized. Any changes in table structure, such as added, removed, or renamed columns in Azure Synapse, should be reflected in your Data Integration configuration.
- Refresh Metadata:
  - Refresh the metadata in your Data Integration environment. This can often resolve issues where cached metadata does not match the current schema.
- Verify Column Mapping:
  - Double-check the column mapping settings in your River to ensure that all source columns are mapped to the correct target columns.
- Examine Logs for Details:
  - Review the logs within Data Integration to pinpoint which columns are causing the mismatch error. Logs can provide detailed insights into what Data Integration expects versus what is currently defined.
- Update to Latest Version:
  - If Data Integration has had recent updates, ensure your current setup is taking advantage of any bug fixes or improvements related to Azure Synapse integration.
- Consult Documentation:
  - Visit Data Integration Azure Synapse Documentation for specific guidance on managing your connection and column synchronization issues.
