Extend S/4HANA Applications Stability Across Updates

Hi all,

currently we are investigating possibilities to extend/modify/customize standard SAPUI5 applications running in S/4HANA 1610. Technically, SAPUI5 provides some cool features to extend standard applications through several concepts as depicted here. One modification which customers can ask for is to change the SAP vocabulary. This can be done easily through the i18n language files. I think we can find more use cases where extension projects might be an option.

My question is how stable are modification across S/4HANA updates. Concrete, if i am changing the language files, using extension points or hook points in the controllers. In all three cases there can be changes in the standard code base such as renaming/removing the language marker file in i18n or remove the extension and hook points.

Is there any information from SAP how stable are extensions across updates. Mean, will SAP modify the code base of many SAPUI5 applications smoothly so that extensions works.

Hope somebody can give me insight/experience about this issue. Maybe somebody already faces some problems from updating S/4HANA from 1511 to 1610.

Best regards,

Manjinder Singh

Hi,

well some customers ask why we should not change the standard apps when it is technically possible. However, the problems occurs when we update the ERP software because then the code base is replaced. My question is only if somebody had faced some problems with that. Or what SAP says in this case. I assume when i use extension points for extending the UI, these changes should be stable over upgrades.

You are right if this not stable then we have arguments not modify the standard apps.

Best regards,

Manjinder
