Use
A transformation has a graphic user interfaces and replaces the transfer rules and update rules with the functionality of the data transfer process (DTP). Transformations are generally used to transform an input format into an output format. A transformation consists of rules. A rule defines how the data content of a target field is determined. Various types of rule are available to the user such as direct transfer, currency translation, unit of measure conversion, routine, read from master data. Block transformations can be realized using different data package-based rule types such as start routine, for example. If the output format has key fields, the defined aggregation behavior is taken into account when the transformation is performed in the output format.
Using a transformation, every (data) source can be converted into the format of the target by using an individual transformation (one-step procedure). An InfoSource is only required for complex transformations (multistep procedures) that cannot be performed in a one-step procedure.
The use of transformations in the load process is restricted to their use in the data transfer process (DTP).
You create a transformation in the context menu of the Data Warehousing Workbench. You can create a transformation for every InfoProvider that is supported by the data transfer process.
Constraints
The following functional limitations currently apply:
● You cannot use hierarchies as the source or target of a transformation.
● You can not use master data as the source of a transformation.
● You cannot use a template to create a transformation.
● No documentation has been created in the metadata repository yet for transformations.
● In the transformation there is no check for referential integrity, the InfoObject transfer routines are not considered and routines cannot be created using the return table.
Effects on Existing Data
You can still use existing transfer rules and update rules. However, new load processes that are based on the data transfer process have to use transformations.
