Reservation of Supply in case of Project Manufacturing

Hi All,

Scenario: Project Manufacturing ASCP

Client wants to have a COMMON SUPPLY sub-inventory which will be used to peg supplies (present in the common supply subinventory) to demand originating from project demands (Project= P1) where there is a Demand.

However there should not be any cross pegging of excess supplies from other projects (Project=P2) to current project (Project=P1)

Objective:

Common Subinventory --> Excess Inventory --> Project P1 (Excess Demand)-----------Required functionality by client

Project P2 --> Excess Inventory --> Project P1 (Excess Demand)----------- NOT Required functionality by client

Is there anyway we can achieve it ?

Thanks in advance for your suggestions.
