Hi Carine,
the link for "Create your first ABAP CDS view" is pointing to same link used for "New Data Modeling Features", is it correct?
Hi Fernanda,
yes, that was the state. I've lightly changed the structure to avoid the confusion.
Kind regards, Carine

This is amazing! Thank you for such a thorough and organized collection of knowledge sources.
Is there an ABAP CDS home page? If not, this should be the basis for it. Well done!
Best regards,
