one of my customer used the MRP procedure as planning in one plant and production in another plant. It is possible by assigning special proc key in the material master of the finished product in planning plant. but by this method i can plan and produce the single material only in one alternative plant.

In some cases i need to produce the finished product more than one alternative plant simultaneously if sufficient capacity is not available at alternative plant. for thisi am thinking of quota arrangement procedure at planning plant ,and procure material more than one alternative plant simultaneously. by defining plant as vendor.. is it possible ???? or there is any alternative solution
