Time Dependent Process Parameters (TDPP) in iPPE (New)

Use

As of release SAP APO 4.0, Integrated Product and Process Engineering (iPPE) is enhanced in APO to support Time Dependent Process Parameters (TDPP) for Production Planning applications.

What are Time Dependent Process Parameters?

TDPP are parameters required for accurate production planning, especially in the semiconductor Industry. They include:

  • Activity Level Yield - (scrap) of product. From the start of production to end of life, the yield received from the production of a product changes. Early production will see a slower, lower yield than later production. At product mid-life, faster production with higher yield values will be achieved.
  • Resource Capacity Consumption - The amount of resource capacity used to produce a product over time changes over the life of the product.
  • Material Consumption - The amount of material consumed to produce a product changes over the life of the product.
  • Activity Duration # The amount of time required to conduct a particular activity during the production of a product changes over the life of that product.

TDPP are version dependent. Supply chain planners use different APO planning versions to perform what-if simulation runs based on different TDPP settings before finalizing the production plan.

Business Scenarios Supported:

TDPPs can be maintained for product variants, shop floor activities, and Supply Network Planning (SNP) activities.

IPPE TDPP Specific Enhancements include:

  • Data modeling to support TDPP in iPPE. Seven new database tables were created in APO to store the TDPP data.
  • User interface enhancement enables TDPP related data maintenance in PPE transaction.
  • Application Programming Interface (API) for TDPP data retrieval and maintenance loads the TDPP data into APO.
  • Enhancement for iPPE order explosion take TDPPs into account.
  • TDPP-ECN conflict resolution report allows users to quickly identify and resolve any conflicts between TDPP and Engineering Change Number (ECN) data.

iPPE TDPP User Interface (UI) Enhancement

A user interface is provided for TDPP maintenance in iPPE. Additional tab strips allow a direct jump to the TDPP screens of the iPPE object.

The TDPP and ECN Conflict Resolution Report

The TDPP and ECN Conflict report provides the user with a one point access tool to identify conflicts that exist between the TDPP and ECN. The TDPP data corresponding to an ECN is displayed, along with a validity icon indicating whether or not the TDPP is valid. The user can then go to the iPPE maintenance transaction and change the invalid data.

API for maintaining TDPP data in APO

An RFC function module (PPEHI_TDPP_MAINTAIN) uploads the TDPP Data into the iPPE structures.

API for reading the TDPP from APO

An RFC function module (PPEHI_TDPP_READ) downloads the TDPP data from the iPPE structures.

Effects on Existing Data

Effects on Data Transfer

Effects on System Administration

Effects on Customizing

TDPPs must be activated in customizing. This customizing controls the visibility of all TDPP related screens and tab strips and also decides whether to check for TDPP parameters during iPPE order creation.
