You define variance keys in this step.

Orders (product cost collectors or manufacturing orders) can only be selected for the variance calculation if a variance key is entered in the order.

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

In Product Cost by Order you usually calculate the variances cumulatively.

In cumulative variance calculation, the target costs are calculated on the basis of the quantity you have transferred to stock for the order. The actual costs are for the entire life of the order. Variance calculation requires that the order have the status DLV (delivered) or TECO (technically completed).

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

In variance calculation by period, the target costs are calculated on the basis of the quantity that you delivered to stock in the period. The actual costs are only for the period in which you calculate variances. Variance calculation requires that a goods receipt was posted for the order in the period. If that is not the case, the system only calculates remaining variances.

The variance key specifies the following:

• Whether the scrap variances are calculated

• Whether a document is written containing the date, user name, and change made (line item)

As a rule, the line item document is not necessary for variance calculation. If, however, you decide to turn on this indicator, you should be prepared for extended run times during the variance calculation.

The following requirements must be met before you can calculate scrap:

• The material must have a standard cost estimate with quantity structure, or another cost estimate in accordance with the valuation variant for work in process and scrap.

• In repetitive manufacturing in Product Cost by Period, reporting point backflushes must be entered.

In repetitive manufacturing, you must specify in the repetitive manufacturing profile whether reporting point quantities can be entered.

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

• You define a variance key as a default value for each plant.

• When you create a material master record, the system proposes a variance key using the default value for that plant.

• When you create a production order or process order to manufacture the material, the system proposes a variance key through the entry in the material master record.

• When you create a product cost collector to manufacture the material, the system uses that variance key as a default value for the product cost collector.

Decide if you want to use the functions Product Cost by Order or Product Cost by Period. Read the section Product Cost by Period or Product Cost by Order? in the Cost Object Controlling documentation. Subsequently, make the necessary settings in Customizing.

The standard system contains predefined variance keys for production orders, process orders, and product cost collectors that you can use as supplied.

Go to the menu option Define Default Variance Keys for Plants and enter the variance key in the table.
