Maintenance Plan/Item Mass Change (MCH01)

All,

I've just been informed about a transaction for mass-change of plans/items (transaction MCH01). But when I run the transaction it doesn't work in my ECC6-EHP5 (IS-OIL) system stating that the transaction cannot be executed.

So I tried running the underlying program (RMCHMPLA) and to my surprise it works...

Has anyone else tried this transaction/program?
