Dual-write has been around for almost two years now. It’s one of the ways of integrating Dynamics 365 Finance and Operations and Dataverse along with Virtual Entities.

The standard solution comes with many out-of-the-box entities available to synchronize. This has been one of the great improvements since Dual-write was made available in preview, when Juanan and I demoed it in the 2019 Dynamics Saturday in Madrid.

But what if we need to develop a new custom Data Entity in MSDyn365FO and use it in Dual-write? It’s easy but there’s some things we need to remember when doing it.
