How to set queue time for work center but category is process unit in PP-PI

Hello guru,

I have one question about set Queue time, Wait time and Move time in SAP, PP-PI.

Now, we set the category of work center is "process unit".  I have no idea what's the different of "process unit" vs. "machine".

So, if we set the category is "process unit", how do I set Queue time, Wait time and Move time?
