## ABAP Environment Overview
The ABAP environment enables cloud ABAP development on SAP BTP.
### Key Features
- Latest ABAP platform cloud release
- SAP HANA database (1:1 per system)
- ABAP RESTful Application Programming Model (RAP)
- Core Data Services (CDS)
- SAP Fiori integration
- Released objects approach for APIs
### Use Cases
| Use Case | Description |
|----------|-------------|
| **Extensions** | Extend S/4HANA Cloud, SuccessFactors |
| **New Apps** | Build cloud-native ABAP applications |
| **Transformation** | Move existing ABAP to cloud |
| **Side-by-Side** | Complement SAP solutions |
### Architecture
```
ABAP System Instance
├── ABAP Runtime (Memory: ABAP Compute Units)
├── SAP HANA Database (Storage: HANA Compute Units)
├── Fiori Launchpad
└── Web Access (ADT, Launchpad)
```
---
## Service Plans and Metering
### Service Plans
| Plan | Use Case | Requirements |
|------|----------|--------------|
| **free** | Proof of concept | Auto-stops nightly, no SLA |
| **standard** | Dev/Test/Prod | Min 2 HANA CU + 1 ABAP CU |
| **saas_oem** | Multitenancy SaaS | Min 2 HANA CU + 1 ABAP CU |
### Compute Units
**ABAP Compute Unit (ACU)**:
- Configures runtime memory
- Measured in 16 GB blocks
- Volatile memory for application execution
- Billed hourly
**HANA Compute Unit (HCU)**:
- Configures persistent storage
- Measured in 16 GB blocks
- Retains data after restart
- Billed hourly
### Entitlement Requirements
For standard plan, assign all three:
1. `abap` service with `standard` plan
2. `abap_compute_unit` with quantity
3. `hana_compute_unit` with quantity
### Minimum Configuration
| Component | Minimum |
|-----------|---------|
| HANA Compute Units | 2 |
| ABAP Compute Units | 1 |
| Total Memory | 48 GB (32 HANA + 16 ABAP) |
### Free Plan Limitations
- Auto-stops every night
- Manual restart via Landscape Portal
- Community support only
- No SLA
- Limited resources

## System Creation
### Prerequisites
1. Subaccount with Cloud Foundry enabled
2. ABAP environment entitlements assigned
3. Space created
### Create via BTP Cockpit
1. Navigate to **Subaccount > Cloud Foundry > Spaces**
2. Open target space
3. Click **SAP HANA Cloud** or **Service Marketplace**
4. Find **ABAP environment**
5. Create instance with parameters:
```json
{
"admin_email": "admin@example.com",
"description": "Development System",
"is_development_allowed": true,
"sapsystemname": "DEV",
"size_of_runtime": 1,
"size_of_persistence": 4
}
```
### Create via CF CLI
```bash
cf create-service abap standard my-abap-system -c '{
"admin_email": "admin@example.com",
"description": "Development System",
"is_development_allowed": true,
"sapsystemname": "DEV",
"size_of_runtime": 1,
"size_of_persistence": 4
}'
```
### System Parameters
| Parameter | Description |
|-----------|-------------|
| `admin_email` | Initial admin user email |
| `sapsystemname` | 3-char system ID |
| `is_development_allowed` | Enable dev features |
| `size_of_runtime` | ABAP Compute Units |
| `size_of_persistence` | HANA Compute Units |
---
## Development Tools
### ABAP Development Tools (ADT)
Eclipse-based IDE for ABAP development:
1. Install Eclipse (latest supported version)
2. Install ADT plugin from SAP update site
3. Connect to ABAP system
**ADT Update Site**: [https://tools.hana.ondemand.com/latest](https://tools.hana.ondemand.com/latest)
### ADT Features
- ABAP Editor with code completion
- CDS Editor
- Debugger
- Unit Test Runner
- Transport Management
- Git Integration (abapGit)
### Connecting ADT
1. **File > New > ABAP Cloud Project**
2. Select **SAP BTP, ABAP Environment**
3. Enter service key or use browser login
4. Select system and log in
### Service Key for ADT
```bash
cf create-service-key my-abap-system my-key
cf service-key my-abap-system my-key
```
### Web Access
| Component | URL Pattern |
|-----------|-------------|
| Fiori Launchpad | `[https://<system>.abap.<region>.hana.ondemand.com/`](https://<system>.abap.<region>.hana.ondemand.com/`) |
| SAP GUI for HTML | Via Fiori Launchpad |
| ADT | Via Eclipse with service key |

## Programming Model
### ABAP RESTful Application Programming Model (RAP)
Modern ABAP development approach:
```
CDS Data Model → Behavior Definition → Service Definition → Service Binding
```
### CDS Data Model
```abap
@AccessControl.authorizationCheck: #CHECK
define root view entity ZI_Product
as select from zproduct
{
key product_id as ProductId,
product_name as ProductName,
@Semantics.amount.currencyCode: 'Currency'
price as Price,
currency as Currency
}
```
### Behavior Definition
```abap
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 )
{
create;
update;
delete;
field ( readonly ) ProductId;
field ( mandatory ) ProductName;
validation validateProduct on save { create; update; }
determination setDefaults on modify { create; }
}
```
### Service Definition
```abap
@EndUserText.label: 'Product Service'
define service ZUI_PRODUCT {
expose ZI_Product as Product;
}
```
### Service Binding
Create via ADT:
1. Right-click service definition
2. New > Service Binding
3. Select binding type (OData V2/V4, UI)
4. Activate and publish
---
## Communication Management
### Communication Scenarios
Predefined integration patterns:
| Type | Description |
|------|-------------|
| **Inbound** | External calls to ABAP |
| **Outbound** | ABAP calls external systems |
### Communication Arrangement
```
Communication Scenario → Communication System → Communication User
```
### Creating Outbound Communication
1. Create Communication System (target system details)
2. Create Outbound Communication User (credentials)
3. Create Communication Arrangement (link scenario + system)
### HTTP Destination
```abap
DATA(lo_destination) = cl_http_destination_provider=>create_by_comm_arrangement(
comm_scenario = 'Z_MY_SCENARIO'
service_id = 'Z_MY_SERVICE'
).
DATA(lo_client) = cl_web_http_client_manager=>create_by_http_destination( lo_destination ).
DATA(lo_response) = lo_client->execute( if_web_http_client=>get ).
```

## Lifecycle Management
### Software Components
Git-based source code management:
```
Software Component (Git repo)
├── Package 1
│ ├── Classes
│ ├── CDS Views
│ └── Services
└── Package 2
```
### Transport Management
| Transport Type | Use |
|----------------|-----|
| **Workbench** | Development objects |
| **Customizing** | Configuration |
### Release and Import
1. Release transport request in source system
2. Export via gCTS or Cloud Transport Management
3. Import to target system
### Landscape Configuration
```
Development → Test → Production
↓ ↓ ↓
Clone Import Import
```

## Integration
### Integrated SAP BTP Services
| Service | Integration |
|---------|-------------|
| SAP Destination Service | Connectivity |
| SAP Build Work Zone | Launchpad |
| SAP Build Process Automation | Workflows |
| SAP Forms by Adobe | PDF forms |
| SAP Cloud Identity Services | Authentication |
### Fiori Elements
Automatic UI generation from CDS annotations:
```abap
@UI.headerInfo: {
typeName: 'Product',
typeNamePlural: 'Products',
title: { type: #STANDARD, value: 'ProductName' }
}
@UI.lineItem: [{ position: 10, label: 'Product ID' }]
@UI.identification: [{ position: 10 }]
ProductId,
```
