Unit effectivity in PCS

In the Project Control module in Manufacturing, effectivity units can be assigned to:

  • Project parts
  • Module planning by project
Project parts

Project parts are used to determine the estimated costs of a project. They are entered manually, or generated from the sales order line (generate project structure from product variant). The PCS calculation of estimated costs uses the standard cost price from CPR to calculate the estimated costs for a standard project part. However, when a standard part has an effectivity unit then the cost price of the part is recalculated to determine the unit effective cost price of that part. In case the BOM of the part has any exceptions for optional material, the unit effective cost price can be substantially different from the standard cost price.

Module planning

Module planning is always entered manually. It is used to trigger Enterprise Planning to create demand when a sales order is not yet available. The effectivity number on the module is used by Enterprise Planning during explosion of the BOM and usage of the routing to determine which objects are valid.

BOMs and routings of customized items

When items are copied to a new structure, an user can choose between two options:

  • Copy all BOM lines and routings with all linked exceptions.
  • Copy only BOM lines and routings that are valid for a specific effectivity unit. Attached exceptions are not copied.

You can choose those options from the following sessions:

  • Copy Standard Product Structure to Customized Structure (tipcs2230m000)
  • Copy Customized Product Structure to Customized Structure (tipcs2231m000)
  • Copy Customized Product Structure to Standard Structure (tipcs2232m000)
To customize unit effective items on a sales order

If you want to customize a unit effective item on a sales order by using the Generate (Project PCS) Structure for Sales Orders (tdsls4244m000) session, a full copy method is used. This means that the complete bill of material as well as all operations, applicable to all effectivity units, are copied to the PCS project. In addition, all exceptions linked to BOM lines and operations are copied.

If you make changes to an effectivity unit in a PCS project, for example, by changing the effectivity unit on the linked sales order, you do not need to regenerate the PCS project because all data related to the unit effective item is already present. Furthermore, the changed design of an effectivity unit is automatically taken into account for the next order planning run in Enterprise Planning.

Note

Unit effective routings are not copied to the PCS project. Similar to routings that are not unit effective, either the default routing of the unit effective item, or a routing based on fixed order quantity or economic order quantity is copied to the PCS project.
