Topic #1 is add-ons.

Many customers extend their SAP ERP application with partner solutions, which are typically delivered as add-ons. In fact, three out of five SAP systems have third-party add-ons.
To keep an add-on upon conversion, you need a version compatible with SAP S/4HANA. That’s why you should review all add-ons early in your project.
Commercially speaking, there are four types of add-ons:

  • SAP add-ons are developed and maintained by SAP, who also provides the installation files. You can check the compatibility and availability of these add-ons for SAP S/4HANA in maintenance planner.

  • Reseller add-ons are developed by SAP partners and can be licensed through SAP. We provide the installation files if the add-on is licensed through us.

  • Certified add-ons are partner solutions certified through SAP Integration and Certification Center. For these, ask your vendor to confirm the add-on’s availability and compatibility and to provide the installation files. You can find the vendor contact information in our certified solution directory .

  • For unknown and non-certified add-ons, you’ll need to identify and contact the respective vendor to check support and availability for the target SAP S/4HANA release. We have no information for these add-ons.

All add-ons must be created with SAP Add-On Assembly Kit software and installed with SAP’s add-on installation tool (“SAINT”). However, occasionally vendors ship extensions in transport files. Technically, these are not add-ons and not covered by maintenance planner. Check if you have any of those in your system to avoid surprises.

We strongly advise you to prepare a simple catalog listing all your add-ons and answering these questions:

  • Is the add-on functionality still required? Is a corresponding functionality available in SAP S/4HANA?

  • What type of add-on is it from a commercial point of view, and who is the vendor?

  • Is the add-on’s compatibility with SAP S/4HANA confirmed by the vendor (or certified by SAP), and if so, for which SAP S/4HANA releases?

  • Is there an upgrade or uninstallation package available for this add-on?

Based on your answers, formulate a plan on how to deal with each add-on:

  • Keep it in the system.

  • Uninstall it. Consider the simulation tool available with support package manager (SPAM) version 7.4 and above. See also SAP Note 2911053 on how to plan and perform uninstallation.

  • Start with the highest release of SAP S/4HANA for which this add-on is available.

  • Contact SAP’s customer care program to help you with the resolution of possible issues.

A few tips to conclude:

  • Execute maintenance planner early in the project.

  • Partner add-ons will only be available after the general availability of the corresponding SAP S/4HANA version.

  • Contact the partner or third-party vendor at an early stage.

  • Clarify licensing terms and potential changes with SAP S/4HANA.

  • Contact the vendor if you want to uninstall an add-on that is currently not available in SAINT.

  • Most add-ons must be co-deployed on SAP S/4HANA and can only run on SAP S/4HANA if they have been explicitly released for it.
