Create and Delete Data with SAP Fiori Elements
You can use the List Report and an Object to create a new object.
By adding a + button to the toolbar, you can navigate to the object page where all fields are editable to create a new object.
You can also delete a record by selecting the radio button on the left of the record and then choosing Delete on the toolbar.
Updating a Record
When you are on an object page, you can use the Edit button to switch between display mode and edit mode. You can also delete this record by choosing Delete.
SAP Fiori elements can also handle the status of a record.
For example, when User A wants to update a record, a draft is created for this record. If User B wants to update this record at the same time, his account is blocked from making the change.
Here you can see the architecture for an SAP Fiori elements application with write capability.
