Validate field selections

The system automatically validates field selections when you configure report fields to ensure compatibility and prevent code generation errors.
Field validation checks include:

• Field compatibility: Verifies that selected fields exist in the specified tables and are accessible.
• Data type validation: Ensures field data types are compatible with the specified field format.
• Usage validation: Confirms that field usage assignments (output, filter, sorting, request filter) are appropriate for the field type.
• Relationship validation: Checks that fields used in table relationships are properly configured.

[!NOTEI]
If validation errors are detected, the system displays error messages indicating which fields have issues and what corrections are needed.
