We live in an ever-evolving world of business improvements and technological advancements. But as industrial workers in this field, it is not enough to simply know about ABAP custom code for S/4HANA migration, neither is it of much value having a peripheral perception about it.
It is essential to master the in-depth operational methods to successfully implement a migration without negative data implementations.
Allow us to help you clean up your ABAP custom code for SAP S/4HANA migration.
The route to take with ABAP code and SAP software
The ABAP Workbench is used by SAP for the development of standard and custom application software. As you probably already know, applications developed by ABAP are operated to copy information from databases, leaving the databases itself untouched.
The copied data is then processed and transformed by the application, and the result presented to the user.
How HANA comes in
SAP developed a new cutting-edge innovation known as HANA. It carries powerful speed and computing supremacy eliminating the need for databases to be copied. However, the entire process of data transformation is done in the database, and only the result is returned.
In other words, there is no need to copy the database and then transfer to the application to transform and compute; only the result is returned to the application.
For users to enjoy the unique features of the SAP HANA, any application that uses the ABAP custom code will have to be adapted to that of the HANA. This also means that any customized ABAP code used by a user to access the unique functions of their databases will have to be wiped off or adapted to successfully migrate to the HANA.
While some custom codes are compatible with HANA, others are not. It is the incompatible ones that need to be cleaned off or adapted to the HANA.
Clearing and migration of ABAP custom code is a step by step by step process
The pre-migration phase involves project planning and preparation. This stage is where you have to reflect on the current situation of your custom code so that you can strategically know your plan for further steps. At this stage, you should consider the following before you start with the migration.
- Limit your work packages so you can get an overview of your custom code. You can do this by analyzing, and eliminate the ones you no longer need for your business.
- Create a custom code directory with the help of the Usage Procedure Log (UPL). The directory will contain only the productively used code.
- Carry out performance optimizations by switching on your SQL Monitor for a week or two and look out for the most executed SQL. (These are the relevant ones that affect business processes).
Begin by correcting functional issues via static and runtime checks and running the static check and code inspector for the variant ‘FUNCTIONAL_DB ‘of your custom code.
Also, do performance optimizations by switching on SQL Monitor and optimize the first Top 10 SQL in your custom code which affects relevant business processes.
At this stage, you need to carry out some functional correction– runtime checks. Switch on the runtime check monitor and make corrections to the result and do Performance optimizations as before.
Finally, optimize your code for SAP S/4HANA migration.
