Objective : simulate changes on resources capacities, and get results through MRP calculation => capacity reservations, planned dates, calculated delays...

Proposed feature : on top of existing resources/calendars relationships (including resources groups calendar deviation), provide new tables/forms to specify master plan dedicated values.

Datamodel : it would be possible to specify calendar value for each record based on key : Resource x Date x Masterplan.

Example : on master plan MP1, apply 7h/day calendar. For the same resource, on master plan MP2, apply a different calendar like 14h/day. (for same resource and same date).
