Function documentation Unit Conversion  Locate the document in its SAP Library structure


You use this function to convert key figure values, that represent quantities, into another unit. Conversion into a common unit means that the balances of the different companies can be compared with each other.


You require this function if you want to plan key figures such as, for example, stock for different companies of your enterprise that use your quantities in units common to different countries or industries. So, for example, fuel stocks can be executed in liters or barrels, weights can be specified in kilograms or Anglo-Saxon pounds and machine runtimes in seconds or minutes.


In order to use this function, the necessary units and conversion keys must be maintained in your system. You make these settings in the SAP Implementation Guide (IMG) under General Settings Check Units of Measurement. You can find more information on the general approach for the management of units of measurement in the SAP System under Concept.


In the definition of a function for unit conversion, in the list of fields for conditions you define the characteristics according to which you want to break down the different unit conversions that the function should carry out. For example, you can make a distinction according to the characteristics country or industry sector.

The function for unit conversion always calculates from the unit in which the key figure is currently conducted into the target unit that is determined by you. During the conversion, it is rounded up or down to the nearest whole number. The function automatically determines all quantity key figures from the planning level and makes them available for unit conversion in the parameter groups. For the characteristic value combinations that result from the selected condition fields, you enter the type of unit conversion that you have chosen. Here you have the following possibilities:

        Key figure
You enter both the initial key figure (from key figure) that you want to translate, and the target key figure (to key figure), in which the translated value should be stored.

The value of the initial key figure is not changed. However, if you specify the same key figure for both fields, the original values of the key figure will be overwritten by those of the target unit.


If, within one parameter group, you translate different initial key figures into the same target key figure, then the values in the target key figure are added up.

You can always define the unit of the initial key figure. Either the key figure has a fixed unit or the unit comes from a characteristic. If the key figure does not have a fixed unit you can determine this (see exchange type and target unit characteristic).

        Conversion unit
Here you enter which unit the key figure should be converted into.

        Characteristic target unit
Here you can select a characteristic that is contained in the unit-bearing planning level, through which the target unit is determined. The data type of the characteristic is not user-defined but has to be able to incorporate units (data type
CUKY in the Data Dictionary).


Defining the target unit with a translation unit or with the target unit characteristic is only allowed if a certain unit for the key figure is not already predetermined in the definition of the target key figure.

You can only define the target unit with one of the methods that are described. If you predetermine a translation unit as well as a unit-bearing characteristic, the system rejects this entry.

The target value is overwritten during the conversion.
