Processes in Repetitive Manufacturing

Purpose

A differentiation is made between two planning processes when using Repetitive Manufacturing in APO:

Repetitive Manufacturing with the Production Process Model (PPM).

You use an R/3 System as OLTP system for this planning process. You maintain all production master data (material master record, BOM, routing, production version) in the R/3 System and then transfer this data to APO. In APO, a production process model is then created automatically which is used as the basis for planning. Alternatively, you can also determine that runtime objects are to be created in APO instead of the production process model and you want to plan using these objects.

The advantage of Repetitive Manufacturing with R/3 and APO is that you do not have to create any new master data to use APO as a planning tool. Plus, you can use the Repetitive Manufacturing functions, such as the pull list, final backflush as well as event-driven KANBAN and KANBAN with planned orders. This is possible as the planned orders are updated in both systems after any change irrespective of which system you use to make the change.

The disadvantages of using this process are listed below:

You cannot plan any configurable products.

When planning, APO does not take the various change statuses of the master data into account which you maintain in R/3 using engineering change management.

When backflushing, you cannot carry out a reporting point backflush.

To avoid the above disadvantages, you can create runtime objects in APO instead of the PPM. Then planning in APO is based on these runtime objects. In this way, you can also plan configurable products and engineering change management is also taken into account when planning in APO.

If you want to use runtime objects instead of the PPM, refer to APO product management for more detailed information.

Repetitive Mfg with Integrated Product & Process Engineering (iPPE) and Production Backflushing in APO.

You use a Discrete Industries System as OLTP system for this planning process. Here, you create all the production master data using the integrated Product and Process Engineering (iPPE) in the DI System and then transfer this data to APO. The iPPE data is copied when being transferred to APO so that the same iPPE structures exist in APO as in the DI System.

Repetitive Manufacturing with iPPE has the advantage that you can also plan configurable products with a high order volume very quickly in APO. A lengthy transfer of the APO planned orders is not required. You can manage the various change statuses of your master data using engineering change management in the DI System. The various change statuses are taken into account when planning in APO. You can also create the production backflush directly in APO.

The disadvantages of using this process are listed below:

You cannot execute any product costing as the iPPE data is not yet linked to Product Cost Planning.

You cannot create any actual activities in the production backflush in APO.

You cannot use the pull list, event-driven KANBAN or KANBAN with planned orders for the products you plan in APO.
