InfoSource 

Definition

A structure consisting of InfoObjects that is used as a non-persistent store for joining two transformations.

Use

When you update data in an InfoProvider, you can connect the source to the InfoProvider directly using a transformation. Subsequently, you do not need an InfoSource for updating the data.

However, if you want to execute two transformations before data is written to the InfoProvider, you need an InfoSource to join these two transformations. This allows you to perform complex transformations, which require multiple transformation steps. The InfoSource forms the connection between the two transformations, without storing the data persistently.

You need an InfoSource if you want to read master data, or use quantity conversions or currency translation. These three functions are available in the second transformation; the transformation that follows the InfoSource.

You can identify InfoObjects in the InfoSource as keys. In the transformation, the data records are then aggregated using the key.

Structure

In contrast to the InfoSource 3.x, as of Release SAP NetWeaver BI 2004s, an InfoSource is an InfoSource with flexible update. The data in an InfoSource is updated to an InfoProvider using transformation rules.
