Input based Recipe

Dear all Gurus,

In a typical Process scenario, i have one issue.

My second stage input depends on First stage output.Based on First stage O/P which is RM for next stage ingredients like acid & other components qty is decided.

e.g RM1 = X ( o/p of first stage)

RM2 = 1.5 times X

RM3 = 1.25 times X

This shows that i don't know o/p of second stage.Then in that case how to create process order for second stage or how to map it in MRP ? Creating a recipe itself become an issue !

Pl.see

Thanks & regards,
