How does the overrides property in source properties function?

The overrides property in the source properties is used specifically to modify a previously defined source, particularly when that source has been included from a package. This functionality is crucial in scenarios where adjustments to the source definition are needed without altering the original source specification in the package itself.

For example, if your project requires different configurations or parameters for the data pulled from a predefined source in a package, the overrides property allows you to redefine aspects of that source directly in your project. This provides flexibility and accommodates changes or enhancements without impacting other projects or users utilizing the same package.

In contrast, options related to user-defined transformations, limiting access, or generating automated source tests do not align with the primary purpose of the overrides property, which is distinctly focused on altering existing source definitions drawn from included packages.
