Hi Ajay,
Thanks for your answer.
I made a mistake, I meant Tcode KCH2 instead of KE52.
I have no problem creating de PC Groups. I am looking for a way to massively assign existing PCs PC Groups (which are not contained in the standard hierarchy). A solution like a Bapi or any other process.
For now, I can assign them individually using Tcode KCH2 (Attached image). But the requirement applies to a large number of PC assignments.
