Purpose

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

Repetitive Manufacturing with the Production Process Model (PPM) or the Production Data Structure (PDS).

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.

Then either a production process model (PPM) or a production data structure (PDS) is created automatically in APO depending on the settings of the integration model which is used as the basis for planning.

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. 

Using a PPM causes the following limitations:

·        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.

Whenusing a PDS, only the backflush with reporting points is not possible.  You can find more information on the PDS in the Documentation on the Production Data Structure. 

 

Repetitive Manufacturing with the integrated Product and Process Engineering (iPPE) and the production backflush 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.
