RawMtl and WIP Forecast and Forecast consumption against WIP Demand

Problem Statement

- We have RawMtl shared between MTS and MTO items

- Maintain stock to build MTS items and when we get a Customer Order for MTO, its steeling RawMtls

- This is causing delay on building FG Stocks

Options tried:

Forecast on RawMtl:

1) Calculated RawMtl WIP usage against FG MTO items

2) Ran Demantra by passing WIP usage as history and generated forecast for 12 months

3) Published RawMtl Forecast to MRP Plan... observed Forecast is not consumed against WIP Demand so we end up over planning (Demantra Forecast and WIP Demand)

Forecast on FG MTO:

1) Collected sales history on MTO items and published to Demantra
