Setup Considerations for PRP
To successfully plan a project by running the MRP/MPS Requirements Planning program for projects, you must verify certain system setup information.
In the Item Master program (P4101), the stocking type for project-specific items is defined with a special handling code of P for project. PRP uses the stocking type to denote that the item is specific to a project.
PRP uses the low-level code to identify the lowest level at which an item resides in a bill of material structure. The low-level code is assigned to an item when the item is added to a manufacturing BOM. An item can reside on a manufacturing BOM, the project work breakdown structure, or both. Because the work breakdown structure is similar to a BOM structure but is not a BOM, the system requires a way to assign an item's low-level code when you use it on a given project. To assign correct low-level codes, run the Bill of Material Structure Analysis program (R30601) with the processing option that is set to consider items in projects.
PRP identifies the supply for project-specific end items on the work breakdown structure when the Shipment field contains the value 1.
You can also set up supply-and-demand inclusion rules for PRP. Consider the statuses of the manufacturing work orders on the work breakdown structure when you use supply-and-demand inclusion rules for PRP.
