It is important that COUs are processed with Deletes first, then Inserts and Updates. This is to ensure that updates are applied in the correct order. Guidance on this can be found in the '[Working with COU data' page in the AddressBase Core Getting Started Guide](/os-downloads/products/addresses-and-names-portfolio/addressbase-core/addressbase-core-getting-started-guide/working-with-cou-data.md).
