How to find BADIS

Category:Programming,SAP,SAP ABAP

Introduction

“Business Add-In” hereinafter BADi, are an extension technology in the SAP environment (Systems, Applications, and Products in Data Processing). BADIs are predefined extension points in the source code of SAP applications, which allow developers to add, modify or customize standard functionality without modifying the original source code. This flexibility makes it easy to adapt SAP systems to the specific needs of an organization without compromising the integrity and future updating of applications. Through clearly defined interfaces, BADIs allow the incorporation of additional business logic and interaction with standard modules, thus contributing to greater agility and efficiency in the management of business processes.

To find and work with BADIs, follow these steps:

  1. Identification of BADIs: First, determine which area or process of SAP you want to extend or customize. Investigate the SAP documentation and manuals related to that functionality to identify if there are BADIs available.
  2. Transaction “SE18”: Access transaction “SE18” on the SAP home screen. This transaction allows you to search and view the definitions of BADIs.
  3. Search for BADIs: In transaction “SE18”, enter the name of the BADI or a keyword related to the functionality you want to extend. This will provide you with a list of relevant BADIs.
  4. Selection of BADI: Select the BADI that best suits your needs. Here you will see the description, the name of the standard implementation and other useful information.
  5. BADI Implementation: Use transaction “SE19” to create an implementation of the selected BADI. You can provide a unique name for the deployment and choose whether it is local (only to your system) or global (spreads to other systems).
  6. Logic Development: In the BADI implementation, you can add your own code to extend or modify the functionality. This allows you to integrate additional business logic according to your requirements.
  7. Deployment Activation: Once you have completed the BADI implementation, activate it using transaction “SE19”. This will link your implementation to the corresponding BADI.
  8. Test and Validation: Perform extensive testing to ensure that your BADI implementation behaves as expected and does not negatively impact standard functionality.

There are several approaches to find BADIS, here you will find four methods to do it

Method 1 : For this method, you must consider that the first step takes into account that the BADIS are registered in the SXS_INTER, SXC_EXIT, SXC_CLASS and SXC_ATTR tables and that they are accessed through the V_EXT_IMP and V_EXT_ACT views. In this way, each existing call to a BADI, the system makes use of the aforementioned tables. Therefore, one method to find the BADI we need is based on the use of transaction ST05(Performance Analysis). The following procedure will be carried out

1. Enter transaction ST05 and once there, select the “Table Buffer trace” checkbox and press the “Activate Trace” button..

2. Next, open a new mode and execute the transaction for which you want to find a BADI.
3. Once the program has been executed, we return to the screen where we had transaction ST05 and click on the “Deactivate Trace” button in order to finish the trace.

4.Once the trace has finished, click on the “Display Trace” button where the Trace will be filtered with the objects: V_EXT_IMP and V_EXT_ACT (views).
5. Press the “Copy (F8)” button, Fill Operations: OPEN and “Enter”.


Result : A list will be obtained with all the “interface class names” of the V_EXT_IMP views starting with IF_EX_*. This is the standard SAP prefix for “BADI class interfaces”. The name of the BADI is found after the prefix IF_EX_. For example, if the interface name is IF_EX_ADDR_LANGU_TO_VERS, the BADI is called ADDR_LANGU_TO_VERS.


Method 2 : From transaction SE80, set a break-point in the “ACT_IMPS_PER_FLT_VAL” method of the “CL_BADI_FLT_DATA_TRANS_AND_DB” class just after the “SELECT” header with the comment “read BADI attributes”.

Then execute the transaction you want to analyze. For each stop at the debugger break-point, examine the “exit_name” and “internal” fields.

Method 3

1.Enter transaction SE24 (Class Builder) place a break-point in the CALL METHOD cl_exithandler=>get_class_name_by_interface which is inside the GET_INSTANCE method of the CL_EXITHANDLER class.

Then, execute the transaction or program to be verified. The variable exit_name shows the names of the BADIs that the program implements. This method can be cumbersome because it stops execution many times, but this ensures that if a BADI exists it will stop at that point. What is being done is putting a BREAK-POINT at the time SAP checks if a BADI definition has any active implementation; therefore, even if there is no active implementation for that particular BADI, the method will detect that a BADI exists at that point. To see if that BADI is implemented or not, go to Transaction SE18 with the name of the BADI obtained in the variable exit_name and go to the menu option 

Implementations → Resume.

Method 4

Obtain the package (Development Class) of the transaction that you want to analyze using the transaction SE93. In transaction SE18, in the expanded search, search by filtering by the previously found package and the system will return all the BADIs related to that package.

At also Eclipse is an integrated development environment (IDE) widely used by ABAP developers for CDS development.

This guide will walk you through the best practices for creating CDS views using Eclipse, ensuring efficient and maintainable code.

Prerequisites:

Before you begin, ensure that you have the following set up:

  1. SAP NetWeaver ABAP Development Tools (ADT) installed in your Eclipse IDE, if you haven’t this tools please follow the instructions from this link https://tools.hana.ondemand.com/#abap
  2. Access to an SAP system with the required authorization to create CDS views.

Step 1:

In order to create a New CDS View To create a new CDS view in Eclipse, follow these steps:

  1. In the Eclipse IDE, open the ABAP Development Perspective.
  2. Right-click on your package or folder where you want to create the CDS view.
  3. Select “New” → “Other ABAP Repository Object.”
  4. In the “New ABAP Repository Object” wizard, select “Core Data Services” → “Data Definition.”
  5. Click “Next” and provide a meaningful name and description for your CDS view.
  6. Choose the package and transport request for your CDS view.
  7. Click “Finish” to create the CDS view.

Step 2:

Define the CDS View Structure Next, define the structure of your CDS view using the CDS Data Definition Language (DDL). Here’s an example of a simple CDS view:

abap
@AbapCatalog.sqlViewName: 'ZCDS_SAMPLE'
@AbapCatalog.compiler.compareFilter: true
@AccessControl.authorizationCheck: #CHECK
@EndUserText.label: 'Sample CDS View'
define view Z_CDS_SAMPLE as select from spfli as Flight {
    key Flight.Carrid,
    key Flight.Connid,
    Flight.Fldate,
    Flight.Price,
    Flight.Currency,
    Flight.Planetype,
    Flight.Seatsmax
} 

Step 3:

Enhance Your CDS View To enhance your CDS view, you can add calculated fields, associations, annotations, and other advanced features. Here’s an example of adding a calculated field and an annotation:

abap
@AbapCatalog.sqlViewName: 'ZCDS_SAMPLE'
@AbapCatalog.compiler.compareFilter: true
@AccessControl.authorizationCheck: #CHECK
@EndUserText.label: 'Sample CDS View'
define view Z_CDS_SAMPLE as select from spfli as Flight {
    key Flight.Carrid,
    key Flight.Connid,
    Flight.Fldate,
    Flight.Price,
    Flight.Currency,
    Flight.Planetype,
    Flight.Seatsmax,
    (Flight.Price * 1.1) as PriceWithTax
} 

Step 4:

Test and Activate Your CDS View After defining your CDS view, it’s essential to test and activate it. To do so, right-click on your CDS view file and select “Activate” from the context menu. Ensure that there are no syntax errors or activation issues.

Step 5:

Utilize Naming Conventions and Documentation To maintain consistency and improve code readability, follow naming conventions for CDS views and its elements.

This practice makes it easier for other developers to understand and use your CDS view.

Step 6:

Perform Regular Code Reviews
Perform regular code reviews of your CDS views to identify any performance bottlenecks, code smells, or areas for improvement.

Performing regular code reviews of your CDS views is crucial to ensure their efficiency and maintainability. Here are some key points to consider during code reviews:

  1. Performance Optimization: Review your CDS view for potential performance bottlenecks. Avoid unnecessary calculations, joins, or filters that could impact query execution time. Consider using appropriate database-specific optimizations like table indexes or partitioning.
  2. Readability and Maintainability: Ensure that your CDS view code is clear, concise, and follows standard naming conventions. Use meaningful names for entities, fields, and annotations. Break down complex logic into smaller, reusable entities or subviews.
  3. Error Handling: Check for proper error handling and error messages in your CDS view. Handle exceptions or unexpected scenarios gracefully and provide meaningful error messages to aid debugging and troubleshooting.
  4. Documentation: Document your CDS view thoroughly, including its purpose, input parameters, output structure, and any assumptions or limitations. Add comments within the code to clarify complex logic or business rules.
  5. Data Access Control: Consider applying appropriate access control annotations (@AccessControl) to restrict access to sensitive data within your CDS view. Follow the principle of least privilege while defining authorization checks.
  6. Test Coverage: Ensure that your CDS view has comprehensive test coverage. Write unit tests to validate different scenarios and edge cases. Verify that the CDS view returns the expected results and handles errors gracefully.

Step 7:

Version Control and Transport Management

To ensure proper version control and transport management of your CDS views, follow these best practices:

  1. Version Control: Store your CDS view source code in a version control system, such as Git. This allows you to track changes, collaborate with other developers, and easily revert to previous versions if needed. Use descriptive commit messages to provide clarity about the changes made.
  2. Transport Requests: Create a transport request for your CDS view to move it between different system landscapes (e.g., development, quality assurance, production). Assign the CDS view and its related artifacts (annotations, data elements, etc.) to the same transport request for consistency.
  3. Transport Route: Follow the established transport route in your organization’s landscape. Ensure that the necessary approvals and quality checks are performed before moving the CDS view to higher landscapes. This helps maintain system integrity and avoids unintended changes in production.
  4. Proper Testing: Before including the CDS view in a transport request, thoroughly test it in the respective system landscape. Perform integration tests, regression tests, and verify the compatibility with dependent objects or applications.
  5. Change Documentation: Document any changes or updates made to the CDS view in the transport request. Include details about the purpose of the changes, any potential impacts, and relevant information for future reference.

Step 8:

Continuous Improvement

CDS views are a vital component of your SAP system, and continuous improvement is crucial to ensure optimal performance and functionality. Consider the following practices:

  1. Performance Monitoring: Monitor the performance of your CDS views and identify areas that can be optimized. Analyze runtime statistics, SQL execution plans, and system logs to identify bottlenecks. Adjust the CDS view structure or implement performance tuning techniques accordingly.
  2. Feedback and Collaboration: Foster a culture of collaboration and feedback within your development team. Encourage developers to share knowledge, exchange ideas, and provide constructive feedback on CDS views. Regularly review and refine your CDS views based on lessons learned and feedback received.
  3. Stay Updated: Stay informed about the latest SAP releases, updates, and best practices related to CDS development. Attend webinars, conferences, and training sessions to stay up-to-date with new features and improvements in CDS modeling.
  4. Code Reusability: Identify opportunities to reuse existing CDS views or elements in new developments. Leverage the modular nature of CDS views to create reusable components, reducing duplication and promoting consistency across applications.
