How to extend a custom VC?

[Bruno Sousa]

Hello,

When I try to extend a already existent custom VC, usually I have an error in the Portal GUI saying that I can't extend a custom VC.

What is the recommend best practice when we want to make a change / extend a custom VC?

Thank you.

Extensions are ONLY for extending an OOTB VC.   Custom VC/MF are controlled 100% by customer so should be directly updated.

The reason for extension was to allow customers to override/append the OOTB MF/VC and not lose their changes if PM updated the MF/VC with new/updated entries.

Jeffrey,

So when we want to change a custom VC / MF we should post (not put, right?) via REST the "full code" for it?

Thank you.

PUT always to update.  POST is for create new MF/VC/component.

And yes, GET the entire custom MF/VC, make your changes, update version, and PUT.
