SAP Build Code fuer ABAP Cloud: KI-gestuetzte Pro-Code Entwicklung

Erstelle eine CDS Interface View fuer Kundenbestellungen mit den Feldern:
- Bestellnummer (Schluessel)
- Kundennummer
- Bestelldatum
- Gesamtbetrag
- Status (offen, in Bearbeitung, abgeschlossen)

@AccessControl.authorizationCheck: #NOT_REQUIRED
@EndUserText.label: 'Kundenbestellungen'
define view entity ZI_CustomerOrder
  as select from zcustomer_order
{
  key order_id       as OrderId,
      customer_id    as CustomerId,
      order_date     as OrderDate,
      @Semantics.amount.currencyCode: 'Currency'
      total_amount   as TotalAmount,
      currency       as Currency,
      @ObjectModel.text.element: ['StatusText']
      status         as Status,

      case status
        when 'O' then 'Offen'
        when 'I' then 'In Bearbeitung'
        when 'C' then 'Abgeschlossen'
        else 'Unbekannt'
      end            as StatusText

Erstelle eine ABAP-Klasse zur Validierung von deutschen Postleitzahlen.
Die Methode soll pruefen, ob eine PLZ genau 5 Ziffern hat.
Generiere auch passende Unit Tests.

Schritte zum Einrichten von SAP Build Code:

1. SAP BTP Cockpit oeffnen
2. Subaccount auswaehlen
3. Services → Instances and Subscriptions
4. "SAP Build Code" suchen und abonnieren
5. Benutzer-Rolle zuweisen: "SAP_Build_Code_User"
6. SAP Build Lobby oeffnen
7. "SAP Build Code" auswaehlen
8. Neues Projekt erstellen oder bestehendes oeffnen

ABAP Cloud System in SAP Build Code verbinden:

1. Projekt oeffnen
2. "Service Center" aufrufen
3. "Add Service" klicken
4. "SAP S/4HANA Cloud" oder "SAP BTP ABAP Environment" waehlen
5. System-URL eingeben
6. Authentifizierung (Benutzer/Passwort oder OAuth)
7. Verbindung testen
8. Services und Objekte durchsuchen

" RAP Business Object in ADT entwickeln
" Behavior Definition
managed implementation in class zbp_i_product unique;
strict ( 2 );

define behavior for ZI_Product alias Product
persistent table zproduct
lock master
authorization master ( instance )
{
  field ( readonly ) ProductId;
  field ( mandatory ) ProductName, Price;

  create;
  update;
  delete;

  action ( features : instance ) setDiscountPrice
    parameter ZA_DiscountInput
    result [1] $self;

  validation validatePrice on save { create; update; }
  determination setCreatedInfo on save { create; }
}

1. Service Center oeffnen
2. ABAP System auswaehlen
3. OData Service suchen (z.B. ZUI_PRODUCT_O4)
4. "Add to Project" klicken
5. Joule: "Erstelle eine Fiori List Report App fuer diesen Service"

Prompt: "Erstelle eine Fiori Elements List Report App fuer
Produkte mit Filterbarer Tabelle, Detail-Navigation
und Erstellungsdialog."

Empfohlener Team-Workflow:

1. Feature-Branch erstellen (Git)
2. ABAP Backend in ADT entwickeln
3. Service testen (OData, Postman)
4. Fiori UI in SAP Build Code + Joule
5. Code Review (Pull Request)
6. Integration Tests
7. Deployment via CI/CD
