For each derivation event you can specify whether the derivation is performed statically or dynamically.

For a static derivation, the attributes determined for the sender batch(es) are transferred to the receiver batch(es).

For a dynamic derivation, no attributes are transferred to the receiver batch(es), in other words, the derivation is simulated and the values are merely displayed. The derivation is saved, but the receiver batch(es) are not automatically changed.

Static derivation is recommended if a batch is newly created or changed and the values in the receiver batch(es) should be filled with the attributes from the sender batch(es).

Dynamic derivation is used when

• the receiver batch must/should not be changed
• the sender values should be used as the basis for a user decision

You specify the derivation type in Customizing for Batch Management under Derivation of Batch Data ® Define Derivation Events

A log is created for both static and dynamic derivations.

When you perform derivation, the following are logged:

• Derivation type
• Derivation event
• Derivation status
• Result of the derivation, as well as the sender batches and the data sent
• Messages that arose during a derivation (for example, error messages when a derivation fails, due to a sender field being non-valuated)

During a dynamic derivation, you can therefore see which data was used as the basis for making a decision.
