Old Transformation Concept 

The transformation process allows you to define rules and consolidate, cleanse, and integrate data. You can define semantic keys for the aggregation.

In releases before SAP NetWeaver 2004s, the central object for the transformation is the InfoSource. The individual fields of the DataSource are assigned to the relevant InfoObjects in it. The data can then be transformed using transfer rules. Update rules specify how the data (key figures, time characteristics, characteristics) is updated into the InfoProvider from the communication structure of an InfoSource. The data can also be transformed in the update rules.

You can continue to use this concept, however, we recommend that you change to the new transformation concept with SAP NetWeaver 2004s. The new concept offers enhanced functionality, better performance, improved log functions and better usability. In addition, the new concept will continue to be developed while the old functionality is not being developed further.

In the new transformation concept you no longer require two different rules, a transfer rule and an update rule; you only need one transformation rule. You edit the transformation rule on an intuitive graphic user interface. InfoSources are no longer mandatory; they are optional and are only required for certain functions. Transformations also provide additional functions such as quantity conversion and the option to create an end routine or expert routine.
