Fix Model Connection Errors

Resolve connection failures between your sheet configuration and data model, including incorrect model paths and status issues.

Fix Type Name Errors

Fix data model entity type naming issues such as spaces, special characters, and mismatched type references.

Fix Relationship Errors

Troubleshoot relationship configuration problems including invalid from/to references and missing link roles.

Fix Multi-Item Column Errors

Resolve issues with multi-item columns displaying incorrectly or failing to save in many-to-many relationships.

Debug Custom Field Issues

Diagnose custom field mapping problems between Polarion fields and data model properties.

Resolve Validation Errors

Identify and fix validation errors that occur during save operations, including constraint violations and data quality issues.

Start by identifying the error category from the message you see in the sheet. Connection and type name errors appear at load time, while validation and save errors appear when editing data. Use the Model Helper Widget to visualize your data model structure and verify binding paths.
