factory calendar assignment

Hi Gurus,

Can anybody please exaplain me the following. We are now running our plant in terms of production process 7 days a week. All these days the the 5 day factory calendar was only assigned. Now the business is wanting to assign the 7 day factory calendar. Here are my questions and this calendar is only for 1 plant.

1) Is there a plaace specifically for each module where the calendaar gets assigned, like sperately for MM, PP etc. Or everything is the same?

2) Where do we assign the new calendar to the plant? Is it in the plant definition in config? or is there a separate place in config for PP modiule only. Please clarify this

Thanks

ANusha
