[@yarsalanpk]

should we not say dual-write is integration basis between business apps instead of still calling it FinOps and CE ? Eventually under the umbrella of D365 all master data would be seemlessly service all business apps

Dynamics 365 "business apps" also include D365BC (Business Central) - Dual Write is not applicable to D365BC; it is related to D365FO and D365CE only
