Question

A company has a new implementation that will use Dynamics 365 Field Service. A developer adds two custom tables to the solution in a development environment. The custom tables have lookup columns to Field Service tables. The developer creates a new test environment and imports the solution. The developer receives an error that states dependencies are missing. You need to recommend a solution for the missing dependencies issue. What should you recommend?

Options

  • AAdd the Field Service tables to the solution.
  • BExport the solution as unmanaged.
  • CAdd the custom tables to the solution.
  • DInstall the Field Service application in test.

Why each option

The missing dependency error when importing a solution with lookups to Field Service tables indicates that the Field Service application and its components are not installed in the target environment.

AAdd the Field Service tables to the solution.

Field Service tables are core components of the Dynamics 365 Field Service application and are installed with the application itself, not manually added to a custom solution.

BExport the solution as unmanaged.

Exporting a solution as unmanaged does not address missing foundational dependencies in the target environment; it only changes the management type of the solution upon import.

CAdd the custom tables to the solution.

The problem states the custom tables are already in the solution; the issue is with their dependencies on Field Service tables, not the custom tables themselves.

DInstall the Field Service application in test.
