Scenario Overview – 1
Purpose and Benefits:
Purpose

To model the complete processing of manufacturing, costing, and lot tracking for
semiconductor and photovoltaic internal manufacturing

This scenario describes a business process, which is typical for semiconductor
and photovoltaic manufacturing including lot-size oriented production.
The production scenario produces a finished good and procures all dependent
components in make-to-stock production (MTS).
Work-in-Process (WIP) Batch is used to record the current properties of the
material on a quantity basis. Furthermore the WIP batch ensures that end-to-end
batch tracing is possible.
This scenario is supported by the main cost object controlling functions required,
such as preliminary costing and period-end closing.

Detailed Process Description:
Manufacturing with Production Order Split and Batch Derivation

This scenario describes a business process, which is typical for semiconductor and photovoltaic
companies with lot size oriented production. The production scenarios includes manufacturing with
down binning and doing production order split with the associated cost collection.

The scenario must support cost object controlling functions such as preliminary costing and period-end
closing with production order split with down binning

The typical planning process starts with sales quantity planning. The previous period’s actual sales
figures can be used as a basis for future planning.

In Sales and Operations Planning, you ensure that production stays in line with sales so that you may
create the production plan synchronously to sales. The planning data is transferred from Sales and
Operations Planning to Demand Management. Demand Management generates independent
requirements, which are used in the subsequent Material Requirements Planning (MRP) run.

In material requirements planning, the bill of materials (BOM) for the top-level material demand gets
exploded and production is planned right down to procured component level. MRP results in planned
orders being generated for the material to be produced.

During production, a production order and the associated lots are split . Production orders are split to
support hot-lots (expedited to meet demand), and in-line rework after some devices fail test.

If insufficient warehouse stock is available, purchase requisitions are created for the raw materials
required. When the order is created, target costs are calculated for the order lot size (preliminary
costing).

Die lots are batch managed

WIP batch is generated during order confirmation for finished product. The corresponding GR batch is
created with reference to WIP batch.

During the production process, costs incurred are updated on the order, which enables you to keep
track of and compare target costs and actual costs at any time.

Period-end-closing activities are applied to the order. This includes Work In Procress calculation and
variance calculation.

After this, Work in Process is settled to financial accounting and production variances are settled to
management and financial accounting.
