Dual-Write for Dynamics 365 – All You Need To Know

Dual-Write for Dynamics 365 - All You Need To Know

Technology is rapidly evolving, and so do Microsoft’s features and documentations. The dual-write infrastructure is a powerful tool to share data across multiple applications. 

Dual-write is an out-of-box infrastructure that gives you a real-time interaction between customer engagement apps and F&O apps. It provides bi-directional integration between Finance and Operations apps and Dataverse. Any data change in the Dataverse causes writes to Finance and Operations apps and likewise, any data change in Finance and Operations apps causes writes to Dataverse. For example, creating a customer in an F & O app creates an account in Microsoft Dataverse and vice versa. This automated flow of data provides an integrated user experience across all those apps. 


Dual-write includes the following features, having an infrastructure that is reliable and extensible.

  • Combined view of activity and error logs for data admins
  • Extensibility for both standard and custom tables and maps
  • Synchronous and bidirectional data flow between applications
  • Ability to configure custom alerts and thresholds, and to subscribe to notifications
  • Synchronization, together with play, pause, and catchup modes to support the system during online and offline/asynchronous modes
  • Out-of-box setup experience for new customers
  • Ability to sync initial data between the applications
  • Intuitive user interface (UI) for filtering and transformations
  • Ability to set and view entity dependencies and relationships
  • Reliable application lifecycle management

Why you should use dual-write:

Dual-write provides data flow and integration across Dynamics 365 apps. This framework links environments and enables multiple business applications to work together. Here are the following reasons to use dual-write:

1. Dual-write provides tightly coupled near-real-time and bidirectional integration between Finance and Operations apps and model-driven apps in Dynamics 365. This integration makes Microsoft Dynamics 365 the one-stop-shop for all your business solutions. Customers who use Dynamics 365 Finance and Dynamics 365 Supply Chain Management, but who use non-Microsoft solutions for customer relationship management (CRM), are moving toward Dynamics 365 for its dual-write support.

2. Data from customers, products, operations, projects, and the Internet of Things (IoT) automatically flows to Dataverse through dual-write. This connection is useful for businesses that are interested in Power Platform expansions.

3. The dual-write infrastructure follows the no-code/low-code principle. Minimal engineering effort is required to extend the standard table-to-table maps and to include custom maps.

4. Dual-write supports both online mode and offline mode. Microsoft is the only company that offers support for online and offline modes.

Seemingly, this addition has the potential for reliable integrations with PowerApps, especially when data is shared among various Dynamics 365 apps. Such tighter integration with Dataverse allows standalone apps to use SDC as a platform to share data with Microsoft Dynamics 365 suite.
