Testing and troubleshooting modules

When a hierarchy is correctly defined, you can run the entire model and all modules connected to the model will run. A model cannot run, however, if any of the following conditions exist:

• Entities (or modules) within the model are invalid.
• A module within the model has inputs in it that are not assigned, either because they have not yet been assigned or there are not enough connectors going into the module to provide input values.
• A module within it has connectors into it that are not used.

If a module is correctly defined, with all module inputs assigned and entities defined, you can run the module on its own to test it. When you run a module in isolation, module inputs are held constant using the same rules as used for the Run Selected Sectors option. For more information, see Module Specs dialog box.
