Executing Material Requirements Planning 
Use
You use MRP planning for the turbine project, to schedule procurement tasks for the material requirements. The system creates planned orders for materials produced in-house, and purchase requisitions for externally procured components.

The procurement type in the material master controls the decision as to whether materials are to be produced in-house, or externally procured. You can check the procurement type for each material component in the Project Builder as follows:
In the structure area, choose a material component
and switch to the Identification and View Selection screen area to the Procurement Parameters tab page. In the Material Master Data, the Procurement field displays the procurement type specified for this material.
Until the Purchasing phase of the project, you only plan the independent requirements for the turbine components via the material components for the activity.
A bill of materials (BOM) and a routing is created for the bearing box. During a project-related MRP run, planned orders are created for the assembly purchase. The T-20600 assembly BOM is exploded in the planning run, and dependent requirements for the components are created.

Via the parameters in the Create Purchase Order field, you have specified that the system creates a purchase order for the externally procured materials.
The system asks you to check the input parameters.
The system plans the material requirements and displays statistics. Purchase requisitions were created for the externally procured materials, and planned orders were created for the in-house materials.
