Define Calculation Schema

In this step, you define the calculation schemas.

In the MM area, a calculation schema - a framework of steps used to calculate or determine something - is used among other things to calculate costs, prices, period-end rebates, and taxes.

Note

This concept is referred to in the Sales and Distribution (SD) area as a pricing procedure.

In the calculation schema (pricing procedure), you specify which condition types are to be taken into account in which sequence.

In the price (or cost) determination process, the SAP System automatically determines which calculation schema is valid for a business transaction and takes into account, one after another, the condition types it contains.

Standard settings

The following calculation schemas are predefined in the standard system. You should not change these schemas.

RM0000 and RM1000

Control the price determination process in POs, quotations, and scheduling agreements.

Both calculation schemas require 2 condition types for the gross price: one for automatic price determination

(standard: PB00) and one for manual maintenance (standard: PBXX). RM0001 and RM1001

Determine which condition types you can enter in purchasing document headers with time-dependent

conditions (e.g. contracts). RM0002, RM1002

Determine which additional condition types you can enter in purchasing document items with time- dependent conditions or in the purchasing info record.

RMMP00

Defines the condition type for determining the market price which can be entered for each material. RM2000

Controls the delivery cost determination process in stock transport orders and stock transport scheduling agreements.

Note

In the calculation schemas RM0000, RM1000, RM0001, and RM1001, the field "Subtotal" must contain the following values in the following lines:

Gross value: 9

Effective value: S

If the interim total 'S' is not set, the PO values cannot be updated in the Purchasing Information System

(PURCHIS).

Actions

1. Check to what extent you can use the calculation schemas provided in the standard SAP System.

2. Create new calculation schemas by copying similar existing ones and changing them.

o Enter a key (length max. six characters) for the schema you wish to create, and a descriptive text.

o For each schema, specify the condition types in the order of their usage, and maintain the relevant data.
