This is not recommended way of doing SAP automation. I would even say “it is forbidden way”!
The automation done in one language should be executed in the same language.
Doing automation on UI level you have to ensure that the tool knows exactly where to click and which activity to perform. Due to different language customisation in SAP, the flow and screens can be different. And you do not want to risk the data corruption in productive environment.
If you want to have Language independent automation, than go on level of API and use SAP BAPI interface and UiPath SAP BAPI activity package
