Best Practice for Customizing Product Entity in OFBiz Without Breaking Updates?

[laprestore]

Hi everyone,

I'm currently working on a custom implementation of OFBiz and need to extend the Product entity to include a few custom fields for a client-specific workflow. I'm aware that directly modifying core entity definitions might cause issues during future OFBiz upgrades.

My question is:
What’s the best practice for customizing or extending the Product entity without interfering with the core and still keeping things upgrade-safe?

Should I be using entitymodel.xml overrides or create a new entity that links to Product? Also, how do you usually handle custom logic in services tied to extended entities?

Any real-world experiences or pointers to documentation/examples would be greatly appreciated!

Thanks in advance,
– Alex
