Introduction
The SAP ABAP development process consists of systematic phases, including business requirement analysis, coding, testing, and go-live. However, a successful development process is not only about well-written code but also about strong documentation.
This article discusses the importance of documentation in SAP ABAP development, the benefits it provides, and the types of documents that should be created at each stage. Additionally, we will examine what information a technical document should contain through an example process.
1. Importance of Documentation and Its Benefits
1.1 Why is Documentation Necessary?
SAP projects are typically large-scale, long-term, and involve multiple business units. Incomplete or incorrect documentation can lead to errors, time losses, and increased costs in later stages.
Proper documentation provides the following advantages:
• Enhances project sustainability: Teams may change over time. Documentation helps new developers onboard quickly.
• Improves communication: Ensures a structured flow of information between business units, consultants, and developers.
• Facilitates maintenance and support: Serves as a reference for troubleshooting and future enhancements after go-live.
• Ensures regulatory compliance: Since SAP systems manage critical business
processes, they may be subject to regulations.
1.2 Benefits of Documentation
a. Increases Efficiency
• Prevents developers and testers from wasting time searching for information.
• Provides a reference point for future developments.
b. Aids in Error Management and Prevention
• Ensures adherence to coding standards.
• Helps detect errors quickly during testing.
c. Supports Sustainability
• Can be reused in similar future projects.
• Acts as a guide for new developers.
d. Ensures Compliance and Standardization
• Aligns with SAP development standards and company policies.
• Simplifies audit processes.
2. Required Documents Before Development
A solid documentation foundation is crucial for a successful development process.
2.1 Business Requirement Document (BRD)
• Defines the business requirements and objectives.
• Explains why the requested changes are needed in the SAP system.
2.2 Functional Specification (FS)
• Translates business requirements into a format understandable by technical teams.
• Describes how users will interact with the system.
2.3 Technical Specification (TS)
• Specifies how the development team will implement the program.
• Includes technical details such as data structures, objects, and performance criteria.
3. Documents Used During Development and Testing
To enhance development quality and minimize errors, the following documents should be created.
3.1 Code Review and Standard Compliance Document
• Ensures that the code adheres to SAP development standards.
3.2 Unit Test and Integration Test Scenarios
• Includes test scenarios and expected results for each development.
3.3 User Acceptance Test (UAT) Document
• A document prepared for end-users to validate the functionality of the development.
4. Documents Required for Go-Live and Post-Go-Live
Once development is completed, specific checks must be performed, and relevant documents should be prepared to ensure a smooth go-live.
4.1 Transport and Go-Live Plan
• Defines the transport sequence, dependencies, and rollback scenarios.
4.2 Go-Live Checklist
• Includes authorization checks, performance tests, and data validation steps.
4.3 User Guide and Training Documents
• Guides users on how to use the new system functionalities.
5. Post-Development Technical Documentation
After development, a technical document should be created to record all changes for maintenance, debugging, and future enhancements.
5.1 Key Sections in the Document
a. General Information:
Development name, description, and change request ID.
b. Development Scope:
• The changes made to the existing system.
c. Used SAP Objects:
• Reports, ALV, SmartForms, BAPIs, Enhancements, table names, and transaction codes.
d. Developed Program/Object Names:
• Example: ZSD_SALES_REPORT
6. Example Development Process: Delivery Report Program
To further illustrate the importance of documentation, let’s consider an example where the business unit requests a Delivery Report Program.
6.1 Business Requirement Document (BRD)
• Users need a program that displays the details of a given delivery number.
• The report should include both the header and item details of the delivery.
6.2 Functional Specification (FS)
• When the user enters a delivery number, the program should retrieve the header details from VL03N.
6.3 Technical Specification (TS)
• The selection screen should contain only VBELN (Delivery Number).
• The program should fetch the required fields from LIKP and display them in an ALV report.
6.4 Code Review and Standard Compliance Document
• The WHERE condition in the SELECT statement must include the delivery number parameter to prevent fetching all deliveries.
• Instead of using SELECT *, only the required fields should be selected for better performance.
6.5 Unit Test and Integration Test Scenarios
• The test system should generate a sample delivery and verify that the program correctly displays the data.
• The output should be compared against SE16N data.
6.6 User Acceptance Test (UAT) Document
• Users should perform similar tests and document their findings in the UAT document.
6.7 Transport and Go-Live Plan
• The following transport sequence should be followed:
1. Workbench Request
2. Customizing Request
6.8 Go-Live Checklist
• Ensure that users have the necessary authorizations for the new transaction code.
6.9 User Guide and Training Documents
• Explain how users can execute the Delivery Report, how to enter the selection parameters, and how to interact with the output.
6.10 Post-Development Technical Documentation
• Change request number: …
• Created transport request numbers: …
• Program name: …
• Associated transaction code: …
• Assigned menu path: …
Conclusion
Documentation plays a crucial role in SAP ABAP development by ensuring successful project management, easier maintenance, and reduced errors. When proper documentation is followed at each stage, developments become more sustainable and manageable.
By following the structured documentation approach outlined in this article, SAP teams can achieve higher efficiency, better compliance, and a smoother development lifecycle.
