11 - Enhancements & Modifications - Customer Exit - Function Module Exit Part1

Summary

This video introduces customer exits in SAP, a method to enhance SAP functionality using a customer namespace. It explains three types of exits: function module, menu, and screen exits. The focus is on function module exits, which allow adding custom code to SAP programs through a specific syntax 'CALL CUSTOMER-FUNCTION' followed by a three-digit number. The video demonstrates how to implement a function module exit in an SAP program and hints at a future example involving a customer requirement for automatically populating the 'Sold-to Party' field in the VA01 transaction code.

Takeaways

• 😀 The session introduces the concept of 'customer exit' in SAP, which is a method to enhance SAP functionality using a customer namespace.
• 🔍 There are three types of customer exits discussed: function module exit, menu exit, and screen exit.
• 📚 The function module exit allows users to add custom code to SAP programs by utilizing function modules.
• 📝 Function module exits have a specific syntax, 'CALL CUSTOMER-FUNCTION', followed by a three-digit number ranging from 000 to 999.
• 💡 The video script provides an example of how to use a function module exit to navigate to a specific function module within an SAP program.
• 🛠️ The function module exit is part of the SAP program, meaning any custom logic written will trigger within the program's context.

The transaction code used to create sales orders in SAP is VA01.

How does the script suggest to address the customer's requirement for automatic population of the 'Sold to Party' field?

The script suggests that this requirement can be addressed by writing custom code using a function module exit in the relevant SAP program.

What is the purpose of the 'customer hyphen function' syntax in the context of function module exits?

The 'customer hyphen function' syntax is used to call a specific function module exit, allowing the insertion of custom code into the SAP program for enhancement purposes.

How does the script indicate that the explanation of fulfilling the customer's requirement will continue?

The script indicates that the explanation will continue in the next video, where they will likely demonstrate how to achieve the requirement of automatically populating the 'Sold to Party' field using a function module exit.

What is the significance of the three-digit number in the 'CALL CUSTOMER-FUNCTION' syntax?
