We in the SAP community are well versed on SAP S/4HANA. After all, it has been live for some years now with several iterations! A lot of our SAP customers have transitioned to SAP S/4HANA, some have started anew and gone with a “greenfield” approach and started building their processes from the ground up, and others have adopted a hybrid approach, retaining some critical business implementations, whilst attempting to leverage the power of SAP HANA and fostering a cloud-like mindset when deploying business critical applications & technologies.

Whichever path you choose for your SAP S/4HANA project, there are always questions around custom code adaptation.

Custom Code?

Custom code, or custom developments are a feature of SAP applications. The ability to garner that extra competitive advantage through SAP’s ‘open source’ policy was for years a major benefit to customers. We still offer that flexibility with SAP S/4HANA, but we want to ensure that it is done in a compliant and effective manner.

After a system conversion to SAP S/4HANA, some existing custom-code objects will not work anymore. As such, there is a need to identify these objects in order to determine:

  1. What code must be adapted in order to work with the new data model in SAP S/4HANA

  2. What code should be adapted to benefit from the power of SAP HANA?

  3. What tools and assessment options are available to identify the impacted custom code developments?

  4. Can we prioritise our worklist, based on business value?

  5. Are there any options for semi-automatic code adaptation?

You need to adapt custom code after a conversion to SAP S/4HANA.

For this reason, SAP Enterprise Support Academy has a live session, the Expert-guided implementation (EGI) – SAP S/4HANA Custom Code Impact Analysis.

Expert-guided implementation (EGI) is a multi-hour remote session, powered by SAP Enterprise Support Academy and delivered over 3-5 working days. They are highly practical, focusing on step-by-step progression through to the completion of a defined task or set of tasks.

The sessions are two-fold:

  • In the online classroom usually 1-2 hours in duration, an SAP expert demonstrates step-by-step the execution of a target activity

  • You then have the support of the SAP expert if you should come across a stumbling block when you execute the demonstrated steps within your own SAP environment or provided cloud system.

  • In order to participate, you must be ready to invest 2 or more hours daily (during the training week).

During the SAP S/4HANA Custom Code Impact Analysis EGI, we will learn:


  1. Why custom code adaptations are needed in a conversion scenario

  2. How to address and distinguish between changes required by the migration to SAP HANA and conversion to SAP S/4HANA respectively

  3. The importance of SAP ABAP Test Cockpit (ATC) and ABAP development Toolkit before and during your SAP S/4HANA project

  4. How to pick the most suitable of the four deployment options of the ATC for your given context/constraints

  5. How to incorporate Usage data provided by ABAP Call Monitor(SCMON) to focus efforts only on those impacted developments which are used.
