The Base Integration Solution is a key component of the integration. The solution adds the required roles and access levels to the user accounts for the integration, and it creates tables that are needed to map the Microsoft Dynamics 365 Business Central company to business units in Dataverse.
By default, the Set Up Dataverse Connection assisted setup guide will import the solution. To do so, the setup guide will use an administrator user account that you specify. This account must be a valid user in Dataverse with the System Administrator security role.
For more information, see Setting Up User Accounts for Integrating with Dataverse and Create users in Microsoft Dynamics 365 (online) and assign security roles.
The administrator account is used only once during setup for the configuration changes that the Base Integration Solution makes in Dataverse. After the solution has been imported, the account won't be needed. Integration continues to use the user account that's automatically created specifically for the integration.
In addition to customizing Dataverse, the solution also creates the following roles in Dataverse for the integration:
Integration Administrator - Allows users to manage the connection between Business Central and Dataverse. Typically, this role is assigned only to the automatically created user account for synchronization.
Integration User - Allows users to access synchronized data. Typically, this role is assigned to the automatically created user account for synchronization and to other users who need to view or access the synchronized data.
During connection setup, the system will create integration table mappings that are needed to synchronize data. Additionally, the system will map entities in Dataverse to tables and table fields in Business Central through integration tables. For more information, see Standard Entity Mapping for Synchronization.
