[ABAP Env] Create Data Model & OData Service
Recently I worked through the tutorial on creating a travel bookings app in the SAP Cloud Platform ABAP Environment.
Find a good introduction and overview on this topic here: Getting Started with ABAP in the Cloud – Part I
And the travel bookings app tutorial here: Getting Started with ABAP in the Cloud – Part II
These are my notes on the steps needed to create the data model and publish it as oData service.
| # | Layer | Nomenclature | Description |
|---|---|---|---|
| 1 | Database Table | ZTABLE | Place your raw data first |
| 2 | Data Definition (Interface View) | ZI_ | Relation between different tables (e.g. currency or text table) |
| 3 | Projection View (Consumption View) | ZC_ | Configure the UI depending on your scenario. Use different projection views for different usages of the same interface view and the same physical table. |
| 4 | Service Definition | ZSD_ | Expose the projection view (and underlying associations like currency, country…) as service |
| 5 | Service Binding | ZSB_ | How to we want to make the service available? Defines the binding type (OData V2 / OData V4) Activate it with the “Activate” Button within the editor window. Select the Entity and hit “Preview…” to see whtat we defined in our projection view. |
If you’ve done this, you are able to view the data in a generated Fiori Elements app. But if you also want to create, edit, delete data, you’ll have to add some behavior functionality.
| 6 | Behavior Definition on Data Definition | ZI_ | Created on top of the Data Definition. Will get the same name es the Data Definition. Implementation Type: Managed Defines the operations create, delete, edit. |
| 7 | Behavior Implementation on Definition View | ZBP_I_ | The code for the behavior… For the travel app tutorial, some logic for a generated unique key and field validation. The class inherits from cl_abap_behavior_handler. |
| 8 | Behavior Definition on Projection View | ZC_ | Created on top of the Projection View. Will get the same name es the Projection View. Defines the operations create, delete, edit. |
