Business Central and Dynamics NAV Object Ranges

In Business Central running the Microsoft cloud we operate with three different object ranges in terms of licensing. Developing for Business Central is done using Visual Studio Code with the AL Language extension. Developing for Dynamics NAV can be done either by using Visual Studio Code with the AL Language extension or by using C/SIDE with an appropriate license file. All tenants in Business Central as of April 2nd, 2018 are able to freely use objects in the following ranges:

  • 50.000-99.999
  • 1.000.000-60.000.000
  • 70.000.000-74.999.999

In the following we will take a look at what the intention of each individual range is. For the latest information about licensing for Business Central, please see the Dynamics 365 Business Central for partners blog.


As in current on premise implementations this range is for per tenant/customer customizations. A partner can develop an extension tailored to the individual tenant to fit the needs. The partner developing this will do this through either using a sandbox tenant (currently in preview) or by obtaining a Docker image of the current release of Business Central that matches the version of the tenant. Once the development is done, the extension can be deployed to the individual tenant


This is the RSP range which partners that have an ISV solution for on premise have access to. By April 2nd, 2018 the partner can choose to use this range for developing extensions that can be used either in Dynamics NAV on premise or in Business Central in the Microsoft Cloud. When used in Business Central these extensions are obtained as apps from


This range continues as it is today. Partners can obtain ranges for extension development that runs in Business Central in the Microsoft Cloud. This range is only available for extension development and only in Business Central. These extensions are obtained as apps from
