Hi js,
You have to talk with your PP and SD Users and also the the consultants and define the process. This is the first step, and then define the flow. Questions:
+ Their production process is 100% make to order?
+ The stock of cement that they consume is produced spetially for for internal consumption or just take some cement from a MTO order, or what is the process they need?
Technically speaking, Your MTO process is with valuated sale order stock ?
If yes, you can move the sales order stock to own (movement 411e), and then consume to the CO order, there is no science in this process
If your MTO is without valuated sales order stock, technically is not possible do the movementfrom sales order to own but indeed work without valuated sales order stock its not common.
There are lot of solutions, but depends on the process in the company... eg you can create a PP order MTS to produce cement and consume to your order...
Wish this give you ideas.
Thanks,
G Rajendhar.
