Transformation 

Use

The transformation process allows you to consolidate, cleanse, and integrate data. You can semantically synchronize data from heterogeneous sources.

When you load data from one BI object into a further BI object, the data is passed through a transformation. A transformation converts the fields of the source into the format of the target.

Features

You create a transformation between a source and a target. The BI objects DataSource, InfoSource, DataStore object, InfoCube, InfoObject and InfoSet serve as source objects. The BI objects InfoSource, InfoObject, DataStore object and InfoCube serve as target objects.

The following figure illustrates how the transformation is integrated in the dataflow:

A transformation consists of at least one transformation rule. Various rule types, transformation types, and routine types are available. These allow you to create very simple to highly complex transformations:

●     Transformation rules: Transformation rules map any number of source fields to at least one target field. You can use different rules types for this.

●     Rule type: A rule type is a specific operation that is applied to the relevant fields using a transformation rule.

For more information, see Rule Type.

●     Transformation type: The transformation type determines how data is written into the fields of the target.

For more information, see Aggregation Type.

●     Rule group: A rule group is a group of transformation rules. Rule groups allow you to combine various rules.

For more information, see Rule Group.

●     Routine: You use routines to implement complex transformation rules yourself. Routines are available as a rule type. There are also routine types that you can use to implement additional transformations.

For more information, see Routines in the Transformation.
