Transfer and Update Rules -> Transformation 

Description

In BW 3.x and earlier releases, there was just one data flow approach for two persistent objects (source and target): a transfer rule, an InfoSource, and an update rule.

As of SAP NetWeaver 2004s, the transformation assumes the functions of the transfer and update rules. You can generally use as many InfoSources as you want (or none at all) in the data flow between a source and target; each of these is linked to transformations.

The 3.x InfoSource is not used by the transformation. There is now a new type of InfoSource that replace this.

For more information, see Transformation.

General Practices with Migration

You can create a transformation from update rules and transfer rules. The corresponding 3.x InfoSource is converted into a (new) InfoSource in the process.

For more information about migrating update rules, 3.x InfoSources, and transfer rules, see Migrating Update Rules, 3.x InfoSources and Transfer Rules.
