Using a multi-tenant deployment of Microsoft Dynamics NAV 2013 R2 and Connector for Microsoft Dynamics
If you are using a multi-tenant deployment of Microsoft Dynamics NAV 2013 R2 and are attempting to integrate your tenants with Microsoft Dynamics CRM using Connector for Microsoft Dynamics, you will currently need to specify alternate ids for your tenants. You then specify these alternate ids in the Microsoft Dynamics NAV adapter URL settings within Connector for Microsoft Dynamics. Stay tuned to this blog for an upcoming release of Connector for Microsoft Dynamics that will fully support the Microsoft Dynamics NAV 2013 R2 tenant URL naming convention without the need to specify alternate ids in the tenant database.
