Materials Planning in Projects
Entering the Requirements Date
When you allocate a material to a network activity, you can either manually set the requirements date or have the system calculate it in relation to the activity dates. The following alternatives exist:
When you allocate a material component to a network activity, you can create preliminary requirements. These can be:
An advance requirement fills an real requirement at a later date. This is useful for materials that have long procurement lead times.
Prerequisites for generating advance requirements:
For further information about planning independent requirements using reference points, refer toMaterial Requirements Planning and the BOM/PS Interface
For more information on planned independent requirements, refer to PP - Demand Management.
Creating Reservations or Purchase Requisitions
MRP relevant reservations or purchase requisitions are created,
You can display the number of the reservation or the purchase requisition on the component detail screen and go directly to the purchase requisition from there.
Displaying Planned Orders and Production Orders
You can display the planned or production orders for the material in the current stock/requirements list. From the Planning menu in the Project System, select Resources® Stock/reqmts list.
Displaying Purchase Orders
You can display the number of the purchase requisition on the detail screen for the component in the network. In the Project Information System: Resources you can display all of the purchase requisitions and purchase orders for all materials in a project.
Displaying the Quantity Received/Withdrawn
You can view the quantity received/withdrawn on the detail screen for the component in the network.
Changes to Quantities and Dates
If you make changes to quantities or dates, the reservations are corrected automatically, planned orders are adjusted in the next MRP run.
Purchase requisitions can be automatically corrected.
If quantities and dates in the activity change and a purchase order has already been created, you can start aWorkflow. The purchasing agent is notified by a mail using SAPOffice about the changes to be made and can change the purchase order(s) directly from the mail.
When you use reference points and theBOM/PS interface to link a material item in a bill of material to a network activity and you change the quantity in the BOM, the change is automatically reflected in the activity as well as in the reservation created for that component.
In the material master you can specify that the material is a discontinued part. If the dependent requirements for this component are no longed covered by plant stock, you can transfer the difference in dependent requirements to a follow-up material. You can also define a follow-up material in the BOM.
For more information onDiscontinued Parts , refer to PP-Bills of Material.
