Define Variance Keys

Orders can only be selected for variance calculation if a variance key is entered in the order.

You can calculate variances either for the entire life of the object (cumulatively) or for a specific posting period (by period).

The decision whether variances are calculated cumulatively or by period used to be made in the variance key. Starting with Release 3.0C the decision is made through the default rule in the order type.

In the Product Cost by Order component, you can calculate variances cumulatively (default rule PP1) or by period (default rule PP2).

In the Product Cost by Period component, you always calculate variances by period.

The variance key specifies the following:

The following requirements are necessary in order to calculate scrap:

The variance key is entered in the master data of the order in the following way:


Through the default rule for the order type, you already specified whether the variances are calculated cumulatively or by period (periodic settlement).

Standard Settings

The standard system contains predefined variance keys for production orders and run schedule headers that you can use without making any changes.


Check whether the existing variance keys meet your requirements. If you require your own variance keys, proceed as follows:

1. Choose New entries and enter a number and a name for the new variance key.
2. Specify whether scrap should be calculated separately.
3. Specify whether a document should be written with information on variance calculation.
4. Save the variance key.
5. Go to the menu option
Define default variance keys for plants and enter the variance key in the table.
