ReportReport
Posted on by Mohammed Marhoon 12

We followings step to create a new tenant database in a multitenant deployment.

1) In SQL Server, create a new database. (Empty Database same collation to the same as the application database)

2) Give the Business Central Server service account privileges to the database

New-NAVCompany -ServerInstance BC170 -Tenant XYZ -CompanyName 'XYZ Ltd'

We are getting error The tenant 'XYZ' is not mounted or does not exist.

3) Mount the database as a tenant to the application.

Mount-NAVTenant –ServerInstance BC170 -Id XYZ –DatabaseServer XXXXXX -DatabaseName 'XXXXXX' -OverwriteTenantIdInDatabase -DatabaseCredentials (Get-Credential)

We are getting error  The XXXXXXX database has version 0 which is not supported by this version of
Microsoft Dynamics 365 Business Central Server. Please contact your administrator.

    On the Business Central database, the service account must have the following roles and permissions:

    db_datareader, db_datawriter, and db_ddladmin database roles

    View change tracking permission on the database schema (dbo)

    You can set permissions directly on the database user that you set up for service account. However, we recommend that you create a role that includes the permissions, and then assign the user to the role.

    For more information please refer to : docs.microsoft.com/.../provision-server-account

    before create company : Mount the database as a tenant to the application.

    To mount the tenant, use the Mount-NAVTenant cmdlet. For example:

    Mount-NAVTenant -ServerInstance BC170 -DatabaseName "XXXXXX " -DatabaseServer XXXXXX  -Tenant BCTenant1 -AllowAppDatabaseWrite

    it is recommend that you use the -AllowAppDatabaseWrite parameter. Later, you can dismount and mount the tenant again without the parameter if needed.

    after that Synchronize the tenant.

    Sync-NAVTenant -ServerInstance BC170 -Tenant BCTenant1 -Mode Sync

    for more information please refer to : docs.microsoft.com/.../devenv-create-databases
