The production of a material for which you have created one or several production lots, in addition to the production of the necessary components are carried out with reference to the production lot (WBS element). The WBS element is displayed in the planned order and in the production order.

You have to enter the production lot number (WBS element) when backflushing or posting goods movements.

You can use the production order management or repetitive manufacturing to control the production of individual production lots.

If you use production orders, you can manage the production lot as valuated individual project stock. You achieve this by using a project profile when creating a production lot and by flagging valuated stock in Customizing for Project System.

If you work with repetitive manufacturing and use final backflush for production lots, you have to use non-valuated individual project stock for the production lot (as of Release 4.5A). You achieve this by using a project profile when creating a production lot and by flagging non-valuated stock in Customizing for Project System.

The following functions are available in repetitive manufacturing to support you when producing the production lot:

In the planning table, you can choose a decompressed representation of the MRP segments. This allows you to display the individual segments of the production lots (project segments) in addition to changing production quantities of a production lot or assigning additional lines.

By entering a WBS element number, you can select particular component requirements: The pull list searches for planned orders which contain the WBS number entered and calculates the component requirements for these planned orders.

The WBS number is then one of many selection criteria in the pull list which are used by the system to determine the missing parts.

The missing parts calculation only refers to the individual project stock when you enter a WBS element. The stock for the project number is managed separately, thus the missing parts calculation is also only carried out with reference to this individual project stock.
