What are dependencies in a custom scoped Application?

[brandonlab2]

I am a beginner in ServiceNow exploring custom application development through ServiceNow studio where I came to see dependencies in the Application settings, what are they , I don't understand them, are they added by default or do we need to add them manually- like if need cross- scope access of multiple files.

Hi @brandonlab2 

Refer: Dependencies for custom applications 

The platform determines dependencies based on the components your application references outside its own scope. Common examples include:

• A business rule that calls a script include from another application.
• A flow that uses an action provided by an installed spoke.
• Any application metadata that explicitly references components outside the application scope.

Also  to access data or scripts across scopes, you must configure the target application's Application Access settings (allowing access from "All application scopes") and handle Cross-Scope Privileges for runtime execution.
