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.

Note: An item cannot be identified as both a project-specific and a standard item within the same branch/plant.For multilevel bills of material, when an item is identified as a project-specific item, all parent items in the hierarchy, including the end item, should also be project-specific items. Otherwise, the originating order requirements (pegging records) cannot be linked.

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.

Note: Initially, when you add an end item to the work breakdown structure, do not add any subassembly items to the work breakdown structure. PRP uses the parent end item's supply work order to explode demand to the subassembly and component items. After processing a work order message, the system updates project-specific subassembly items on the work breakdown structure.

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.
