Recovery and Fresh Solvent for MRP planning

Dear Experts,

Need your help in below scenario.

We are working for a chemical industry and a facing a constraint in planning and consumption of a raw material which is Solvent

The solvent is assigned in number of BOMS. Now, please find the below BOM structure.

Header Material( X)- Halb QTY-1L

Components---------- ROH1(1L), ROH2(1L), ROH3(10L)(Solvent)

Out of this 10 L of Solvent, 20% gets consumed in the process and 80% is received as MLR( Mother Liquor)

This MLR is further recycled to get the fresh Solvent which is ROH3.

Concerns

1) How will we design the BOM in which 20% Fresh solvent is consumed and rest 80% Solvent is obtained as MLR? same material code or different?

2) Again 80% solvent is recycled to get fresh solvent, so how MRP planning will work out so that system should first consider recycled version of solvent stock and should trigger the requirement for Fresh solvent as per the BOM qty?

Appreciate your valuable inputs

best regards

Shailesh

    Hello,

    Received as MLR( Mother Liquor) should be a by-product in this case and it should be the part of BOM with different material code. So while confirmation it will increase the inventory of the MLR( Mother Liquor)

    This MLR is further recycled to get the fresh Solvent which is ROH3. Here you can do the material to material transfer or create the production/process order to convert MLR to ROH3.
