Custom code, similar to Dynamic Code (Dynpro), is one of the most powerful features in SAP. It can be used to do anything from automating tasks to creating new functionality. As with any software, customizing your own SAP system has its advantages and disadvantages. In this post, we will explore how custom code works, explain the importance of custom code management and how to do it in SAP so you can make an informed decision about whether or not to use it for your business needs.
Custom code management is the process of organizing, managing, and governing your custom code in SAP. It is a crucial step to ensure that your SAP system remains efficient and stable. Without proper custom code management, your SAP system can quickly become cluttered and unstable.
Importance of Custom Code Management
- Custom code management enables you to tune the performance of your SAP system.
- Custom code management provides full transparency into changes made to an SAP system, thus making it easier for you to roll back customizations if anything goes wrong with them.
- While custom coding is powerful, it also reduces the operational stability and security of the solution provided by SAP.
- Custom code management is an important process to ensure that your SAP system remains efficient and stable.
- Without proper custom code management, your SAP system can quickly become cluttered and unstable.
How Custom Code Management Works
- The first step in custom code management is to create a repository for your custom code. This can be done in a number of ways, such as creating a dedicated folder on your hard drive, setting up a shared network drive, or using a repository management tool.
- The next step is to organize your custom code into libraries. This can be done by function or module, depending on how your company uses SAP.
- Once your code is organized, you need to create and apply coding standards to ensure that all of the custom code in your system is written and executed uniformly. This ensures that the overall performance of your SAP system remains stable.
- The final step when it comes to custom code management is to apply change control procedures to all changes made to your SAP system, which will ensure consistency and transparency when using your SAP system
Four Dimensions of Custom Code Management
- Quality
It ensures that custom code in your SAP system is written correctly and that all codes follow best practices when it comes to data manipulation.
Without quality controls, you run the risk of errors caused by using incorrect syntaxes or manipulating incorrect data types. This can lead to unpredictable results and system instability.
- Quantity
Quantity is the number of custom code objects in your SAP system. As your SAP system grows, more custom code objects are required to maintain it.
For example, if you have 50 different programs containing 200 lines of code each, then the total amount of custom code would be 10,000. If anyone program fails, it will also be necessary to perform a system-wide check of all custom code to ensure that it works correctly.
- Technical severity
Technical severity is how severe the impact of a custom code failure will be on your SAP system.
For example, a program that deletes data from your production database would have a much more severe impact than a program that simply prints out some text on the screen.
It is important to understand the severity of each custom code object in order to properly prioritize remediation efforts.
- Business criticality
Business criticality is how vital a custom code object is to the business. This can be determined by factors such as the amount of revenue generated by the solution, the number of customers impacted, or the level of service provided by the system.
Critical custom code objects should be given a higher priority when it comes to fixing issues and maintaining stability.
There are a few key things to keep in mind when managing your custom code in SAP:
- Organize your code into manageable chunks. This will make it easier to find and troubleshoot errors.
- Use comments to document your code. These should explain what each piece of code does and provide information that will help you troubleshoot any problems.
- Standardize your code to make it easier to maintain, update and extend. Using standard naming conventions for components and macros is a great way to do this.
- Use separate customizing objects for different areas of the system. This will make it easier to find and maintain your code.
SAP Custom Code Final Thought
Custom code management is an essential part of any SAP deployment. When managing custom code in SAP, it is important to understand that you cannot completely eliminate the risk of errors and failures.
However, you can reduce the risk by following best practices and using standard productivity tools. Managing custom code well will help your business run more efficiently and effectively.
