Run Program
Introduction
Happy New Year! I hope you were all able to stay safe and enjoy your holiday. As always, I want to thank everyone who has been following this series. I hope you find it helpful and follow these steps to get you started as an ABAP Developer.
This is the third post in this series. Here is the previous blog post: Get Started with Your SAP ABAP Journey: Part 2.
In the previous blog post, we continued the installation process by running our Docker container and creating an ABAP package to structure our development objects. We will now build and run an ABAP application.
This exercise is based on tables of the SAP NetWeaver Demo sample EPM Model so that you can complete the tutorial on any SAP NetWeaver system. The EPM (Enterprise Procurement Model) is a demo application that integrates many SAP NetWeaver technologies used by SAP S/4HANA applications. It is based on a common business process model and follows the business object (BO) paradigm to support well-defined business logic.
This blog post also follows up with a video that walks you through the steps I will be going over.

Prerequisites:
Creating new ABAP Program
Before creating an ABAP program, we need to make sure that our Docker Container is running and we have the SAP GUI system connected. Once we have done so, it is now time to launch Eclipse.
ABAP programs are objects of the Repository. Each repository object is assigned to a package. You maintain them by using an ABAP Workbench tool - in this case, the ABAP Editor.
Please refer to SAP Help Portal to learn more about the ABAP Workbench Tools.
New ABAP Program
When we create a new ABAP program, it is important to know that the program name must adhere to the customer naming conventions, meaning that here we must use the letter Z. In this instance, the program will be named ‘Z_invoice_items_euro', which should be typed into the ‘name field.’ Afterward, an editor will be opened, which shows the empty report where we will be writing our code.
Create an ABAP local class

The first set of lines visible here are comment lines. These five lines can be used to begin commenting the program. In ABAP, comments can appear in two ways. If a * is placed at the beginning of a line, it turns everything to its right into a comment. The following line of code begins with the word REPORT. This is called a STATEMENT, and the REPORT statement will always be the first line of any executable program created.
As a newbie, it's important to note that a complete stop or period must follow every statement in ABAP. As you see in our above code, we closed out all our statement with a period. This allows the statement to take up as many lines in the editor as it needs.
Activate ABAP program
Activate ABAP program
Once we have successfully made our ABAP program runnable following the interactive tutorial or video above, we will save and activate our ABAP program by clicking Save and Activate in the toolbar.
Run ABAP program
To run our program, we choose F8 or Cmd +1 on Mac. Our output now includes our username and today’s date.
What’s Next: Display Database Content and Run SQL Queries
We have now successfully created and run our first ABAP application. Now that you are familiar with the program, we will display database content and run SQL queries using Data Preview in the next blog post.
