Controlling Mandatory Fields in Embedded Table View

Hello Experts,

I am trying to implement checks on mandatory fields in a Table view created with AET. The Table view is in component ZAET_COMPONENT and was embedded in the account overview page.

I am able to trigger error messages to the global message container, but when pressing the "Save" button on the Account overview page, the database table behind my table view is updated regardless of the errors.

What would be the best way to avoid saving the data when errors exist?

I have noticed that in method EH_ONSAVE the global message container is empty.

Please see the attached photo for more details.

Thanks,

Yordan
