Allocation of moulds cost to units produced....

Hi All,

I have an issue... need ur expert opinion on it....

Client is using the die for producing the material...one die is used for sometime...may be it produces 100 or 200 or 500 units...we dont know the exact quantity.

Problem is that client want to allocate the cost of the die on produced units...on no of production orders...at month end. How can we do that???

Thanks in advance,

Rajesh
