Fiori extension vs New App and extending component-preload.js

[Former Member]

Hi Community

I am new to Fiori development and need to extend a set of SAP delivered Fiori apps and the OData services supporting them. I have tried to research extending Fiori apps as best I can, but I have mostly found fairly simple extension scenarios. It looks like the available extension points are not sufficient so would need to extend using the extension points available, replacing views, modifying controllers and component-preload.js.

I have several questions as follows:

At what point should you continue with extending an app versus creating a new app as the modifications are extensive?

Are you able to import a standard SAP app and essentially turn it into a Z app rather than extend it?

I have the OData source specified in component-preload.js so need to change it. How do I do this in an extension project?

Thanks for your assistance

Some extra information - the component-preload.js contains:

and manifest.json has:

How do I do the extension in this scenario and change the data source?
