Organizational unit <<NAME>> is locked by <<USER>>
I'm at the University THM Mittelhessen in Germany and I'm teaching the SAP HR Basics.
In this case, the students have an exercise to create positions in the transaction PPOME.
If the students start the exercise, the first of them can do it, the others get the message: Organizational unit <<NAME>> is locked by <<USER>>, Message-ID: 5A498.
What can I do? In my last course this message didn't appear.
