DATA(lv_matnr) = VALUE matnr( 0000000001 ).
DATA(character_string) = VALUE string( ).
character_string = |Your Material Number is { lv_matnr ALPHA = IN }|. "Adds leading zeros
character_string = |Your Material Number is { lv_matnr ALPHA = OUT }|. "Removes leading zeros
These are my notes on the steps needed to create the data model and publish it as oData service.

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.
