Master Data Management System (MDMS) is an app that allows corporate groups to ensure data consistency across the whole organization by setting up sets of data within a Dynamics 365 Business Central tenant/company and replicating them to another tenant/company. 

The MDMS app is a continuation of the long-established on-premises version that is already used by 40 corporate groups bringing together 450 companies. Each day, 4000 users work in Dynamics 365 Business Central or Dynamics NAV with master data synchronized by MDMS. 

Advanced Intercompany for Microsoft Dynamics 365 Business Central allows corporate groups and partner companies to exchange purchase and sales documents in real-time, ensuring instant feedback, control, and collaboration. With its innovative features for transaction processing and document synchronization, the app extends the Intercompany functionality in Business Central. 

With Intercompany Insights, groups of companies can optimize item availability, by reducing slow-moving inventory quantities. In different documents in Microsoft Dynamics 365 Business Central, you can use fields, actions and FactBoxes to view information on availability of items in other companies within the group. Inventory availability in different companies and locations can be also displayed in a matrix. You can check inventory availability per item or item variant in the companies selected. In addition, the app enables you to view item quantity on sales, purchase and manufacturing documents. Inventory availability information can be displayed from sales and purchase documents and in the inventory journal.
