I have an app with multiple different CDS entities connected to it. The EditForms that are auto-generated from the app for these datasources are extremely helpful because there is no need to type out a huge Patch function for all of these entities. But unfortunately I am noticing that some of the cards have no Update property. Most of them usually do, but out of perhaps 20 cards I might have 2 without the property. I see locked and unlocked cards with and without Update properties as well, so it does not have to do with that.
I would just like to know if this is a new update to get rid of it or if the presence of the Update property depends on something else. Basically, is this a bug, a feature, or a misunderstanding of how DataCards work?
