augment_update Method not called

[sebastian_wilhelm1]

Hi experts!

I have a RAP App on the BTP where I want use augmentation for update. The problem is, that the method is not called.

The implementation is

Projection BDEF 

use update (augment);

Projection Implementation

METHODS augment_update FOR MODIFY
  IMPORTING entities FOR UPDATE DemoArticle.

Szenario: Managed, OData V4

Does anyone knows, why the implementation is not called?

Thanks and regards, Sebastian

The augment methods are called before the save routine - after pressing the "Save" or "Create" button on the object page. And only, if there has been changes on the BO
