- When User Defined Attributes (UDAs) are managed through the Data Loader (CDIF or DLA uploads), each CDIF upload is treated as the current source of truth. The system processes UDA data using a delete-and-load mechanism.
- If a CDIF file is uploaded without UDA columns, any previously loaded UDA values are cleared and replaced with empty values.
- As a result, UDA information will no longer appear on the platform or in validation reports.
