Rescheduling the operations

Hi Gurus,

We have to assign the employees against operations in work order and for this we are using the SAP tool of graphical analysis I.e., CM30.

Now query:

1. When we assign the employees we also reschedule operations based on their availability (drag n drop). But this is not updating the scheduled start date, time, end date and time in order. How do we achieve this?

2. Also any table or functional module using which we can find this employee wise time assignment against order?

Regards,
