WorthKnowing: Adding system fields in data entity

Hi Folks, 

System fields like CreatedBy, CreatedDateTime, ModifiedBy, and ModifiedDateTime appear in a D365FO entity’s metadata, but they don’t show up in exports or OData. This happens because system fields aren’t automatically exposed through the staging table.

To make them available, create wrapper fields with different names—such as CreatedBy1, CreatedDateTime1, ModifiedBy1, and ModifiedDateTime1—and map them to the system fields.

- Add the new fields to the staging table or its extension.

- Add them to the data entity and map each one to the corresponding system field.

- Build and synchronize the project.

- Export or call the entity via OData to confirm the fields appear.

This simple approach ensures audit fields are available for integrations, exports, and reporting.
