Automatic creation planned order according to raw material stock level

[Kareem-Hany]

Hello All,
I have a case that the a production order (X) of a semi-finished product (A) also produces a by-product (B) which is accumulated in a storage location, this by-product (B) is re-processed by a production order (Y) to produce the raw material of production order (X).
But in this case the production order (Y) should occur ONLY IF the stock level of the by-product (B) reaches a certain quantity (lets say 100 kg).

How could i automate the creation of a planned order in MRP if the stock value of a raw material reaches 100 kg ?

This kind of scenario cannot be covered by MRP, because MRP planning is always top down, that means, it first plans the header material and then plans the components.

My suggestion for you is to set a reorder point for for material Y and let MRP always generate a new planned order. Then you run periodically the ATP check on this planned order and only convert it to production order when the total quantity of the component is available.
