Regarding workcenter capacity and scheduling

Hi Experts,

I have created a workcentre and maintained all formula's for each activity in the workcentre.Now what I want is that, while confirming the activity , If workcentre gets overloaded beyond tolerance limit then it must issue a warning message and wont allow us to confirm that much activity.

Case 2:

If capacity is overloaded then the timeframe also should mave accordingly as automatic scheduling.

your valuable suggestion would be highly appreciated
