Integrated Product and Process Engineering (iPPE)

Use

iPPe uses a data model to map the master data of products throughout the whole life cycle from the early phase and production up to operative use and disposal. In addition, the Product Variant Structure (PVS) function, which was introduced in the SAP Automotive Release 1.0, has been enhanced to include the routing and line design functions from integrated Product and Process Engineering (iPPE) for the SAP Automotive Release 2.0 (DI 4.6B) and the APO Release 3.0A (First Customer Shipment and Support Package 1). You maintain these three applications in the same place and their functions are linked to each other.

Application Objects for iPPE

You can use iPPE to maintain master data for both configurable products and non-configurable products. The Product Variant Structure (PVS) displays the data for configurable products and the variant assembly displays the data for non-configurable products. The PVS and variant assembly functions are grouped together in the product structure function.

By using classes and characteristics from the SAP classification system, you can also map platform strategies in iPPE and configure the corresponding products.

For further information about product structure, see the release note iPPE Product Structure.

The iPPE routing function (iPPE Process Structure) contains data for planning workflows on production lines with takts where the same or similar products are always processed. The process structure is the basis for line balancing in Line Design (iPPE Factory Layout).

For further information about iPPE process structure, see the release note iPPE Process Structure.

Line Design (iPPE Factory Layout) helps you to create the structure and properties of production lines as master data in your system, within iPPE. For complex lines, you can carry out a line balance, in which you can determine the optimum work content of the individual line segments.

For further information about iPPE Line Design (Factory Layout), see the release note iPPE Line Design.

User Profile and Interface

Integrated Product and Process Engineering contains the maintenance and management of all master data that affects the life cycle of a product. It is therefore useful to restrict the quantity of data that is available for an individual user. In iPPE, you can use user profiles to do this. You can define these user profiles for individual work areas, for example, process planners and BOM engineers. You can then assign one or more users to these profiles. This ensures that the employees only see data (from the iPPE data) that directly affects their work areas.

The iPPE interface is laid out in such a way that you can view and process iPPE structures on the left-hand side of the screen and view detailed information about an object at the same time on the right-hand side.

Structure of iPPE

Integrated Product and Process Engineering covers the maintenance and management of several types of master data. The data model and related objects are therefore abstract and are put into a concrete form for the respective application in Customizing.

Integrated Product and Process Engineering consists of the following technical objects:

• Nodes:

Nodes represent general functions in the product. In the product structure, there is a node Body that, for example, shows that a body must be available in the product. The concrete material, which in this case, for example, is a body combi, is maintained as a variant at the node. The quantity of variants is not limited for a node and the node is always assigned to a concrete material that is required for the product to be produced.

• Variants:

Variants represent the concrete forms of a node. If a customer can, for example, choose between 5 different types of radio for a car, every type of radio has a variant at the node. In addition, every variant is assigned to a concrete radio that can finally be selected for the finished product using the object dependencies.

• Alternatives:

If a product has a different explosion for each location for example, this can be mapped using the alternatives at the node. For this, it is not necessary to build a new product structure. The alternative can be used for this alternative explosion and thereby documents the same product structure.

In the case of the process structure, the alternative (mode) determines the resource assignment for the respective activity in the routing.

• Relationship:

The relationship links the technical application objects with each other. The relationships that are possible in iPPE are defined in Customizing. However, you cannot see them.

For all iPPE application objects, you can maintain structures and data at an abstract or functional level without concrete products existing in the system, for example. You can then enter concrete data for these structures during the following phases in the life cycle that the product goes through.

Effects on Existing Data

You can migrate classical BOMs and routings to objects and structures in iPPE by using a migration tool in SAP Automotive 2.0. You can then transfer the migrated objects to APO 3.0A (FCS and SP1) by using the CIF interface.

It is possible to maintain and create iPPE data and structures both in the DI System and the APO System. In order to ensure an integrated scenario, it is necessary to maintain data in the DI System first and then to transfer the data into the APO System using the CIF interface. The planning is then executed there and the subsequent backflush is executed in the DI System again.

Effects on System Administration

Effects on Customizing

iPPE Customizing can be found under Advanced Planner and Optimizer (APO) ->Master data -> integrated Product and Process Engineering.
