Ours is a Contract manufacturing scenario where we deal with a limited number of contract manufacturers(CM's) to get our finished goods manufactured. We are implementing Supply Planning and Supply Chain Collaboration with contract manufacturing features.

To model our supply chain, we have defined a MPS Supply Plan for Finished Goods(Make items). We are planning to upload the detailed production schedule from the CM's as firm planned orders (not overriddable) in our Supply Plan using REST API.

In the following two cases the total demand would be more than supply even after taking the CM related planned orders into account.
