What is SAP Transaction PE03?

SAP Transaction PE03 is used to create and maintain function groups and function modules in SAP. Function groups are a collection of function modules that serve a common purpose or belong to a specific category. Function modules, on the other hand, are reusable blocks of code that perform specific tasks within SAP.

Step 1: Accessing SAP Transaction PE03

To access PE03, follow these steps:

1. Login to your SAP system using your user ID and password.
2. Launch the SAP Easy Access Menu.
3. Navigate to the “Tools” folder and expand it.
4. Locate and click on the “ABAP Workbench” folder.
5. From the sub-menu, select “Development” and click on “Function Builder” to proceed to the PE03 transaction.

Step 2: Understanding PE03 Transaction Screen

Once you have accessed PE03, you will encounter the transaction screen, which consists of various fields and tabs. Let’s explore each of them:

• Function Group: In this field, enter the name of the function group you want to create or maintain. A function group serves as a container for function modules.
• Function Module: This field displays the list of function modules within the selected function group. You can select a specific function module to maintain or create a new one.
• Attributes Tab: This tab allows you to define and maintain attributes for the selected function module, such as its name, type, interface, and visibility.
• Source Code Tab: Here, you can write and maintain the ABAP source code for the selected function module.
• Documentation Tab: The documentation tab provides a space for you to add comments, descriptions, and other relevant information about the function module.

Step 3: Creating a Function Group

To create a function group, follow these steps:

1. On the PE03 transaction screen, enter a unique name for the function group in the “Function Group” field.
2. Click on the “Create” button to create the function group.
3. In the “Attributes” tab, specify the necessary details for the function group, such as its description and other attributes.
4. Click on the “Save” button to save the function group.

Congratulations! You have successfully created a function group using SAP transaction PE03.

Step 4: Creating a Function Module

To create a function module within a function group, follow these steps:

1. Select the function group in which you want to create the function module from the “Function Group” field.
2. Click on the “Create” button to create a new function module.
3. In the “Attributes” tab, specify the necessary details for the function module, such as its name, type, interface, and other attributes.
4. In the “Source Code” tab, write the ABAP source code for the function module.
5. In the “Documentation” tab, add any relevant comments or descriptions for the function module.
6. Click on the “Save” button to save the function module.

Well done! You have successfully created a function module using SAP transaction PE03.
