CDS with BOPF - CRUD operations on association

Hi,

I created CDS views and a BOPF object from them. My model is classical :

- Header level

- Association to item level

Both header and items are "creatable", "updatable" and "deletable". I can see it on the BOPF object generated.

If I check the Fiori List Report UI, it works fine for the header, but not for the items: I can only see de "Delete" button on the item table.

Do you have any idea what can be the problem ?

Thank you.
