Dear SAPLearners, in this blog post we will learn to create an ABAP program in SAP Cloud Platform ABAP environment.

Prerequisites

Before you start, make sure you have

I know you are very much exited to write your first ABAP program/class in SAP Cloud Platform and also got few questions in your mind. Lets get answers to those first

What will be the IDE which i am going to use with ABAP in Cloud system?

The answer is Eclipse ABAP Development Tools

No, you cannot.

Below is the list of ABAP Repository Objects you can create in ABAP system in cloud.

1. Dictionary

Data Element
Database Table
Domain
Dynamic Cache
Lock Object
Structure
Table Type

2. Message Classes

3. ABAP Package

4. Source Code Library

ABAP Class
ABAP Function Group
ABAP Function Module
ABAP Interface

5. Transformations

6. Core Data Services (CDS)

Data Definition
Access Control
Metadata Extension
Behavior Definition

7. Connectivity

HTTP Service

8. Cloud Communication Management

Communication Scenario

9. Cloud Identity and Access Management

Service Binding

11. Authorizations

Authorization Field

The above list may change and new repository objects get added in new releases.

Now that you have understanding of what you can do in cloud ABAP system. Lets create demo ABAP application.

Step-by-Step Procedure

#Create ABAP Package

1. Right-click on ZLOCAL package and choose New -> ABAP Package from the context menu

2. Provide Name and Description of the ABAP package and click Next

3. Hit Next

4. Choose the Transport Request and hit Finish.

5. A new ABAP Package is created. Navigate to the package, right-click and choose New -> ABAP Class.

6. Provide Name and Description of the ABAP class and click Next

7. Select the transport request and hit Finish

8. A new ABAP class is created, copy and paste the below code

CLASS zcloud_demo DEFINITION
  PUBLIC
  FINAL
  CREATE PUBLIC .

  PUBLIC SECTION.
    INTERFACES if_oo_adt_classrun.
  PROTECTED SECTION.
  PRIVATE SECTION.
ENDCLASS.


CLASS zcloud_demo IMPLEMENTATION.
  METHOD if_oo_adt_classrun~main.
    out->write('Hello ABAP in Cloud!').
  ENDMETHOD.
ENDCLASS.

In above code interface IF_OO_ADT_CLASSRUN provides a light-weight solution for executing an ABAP program without launching the integrated SAP GUI.

9. Save and activate code changes.

10. Finally run the ABAP class to see the output in ABAP Console.
