Editing Characteristic Derivations 

Characteristic derivation allows the SAP system to deduce characteristic values on the basis of certain other characteristic values. This enables the system to supply values automatically to characteristics, and in accordance with certain rules.

You have to set up the logical relationships between the characteristic values beforehand by defining derivation strategies or derivation rules. In each client, each analysis structure has precisely one derivation strategy.

Risk Analysis differentiates between the following derivation strategies:

Types	Menu paths (only for maintaining the rule entries)	Customizing (for maintaining the strategies)
Type 1	Master Data ® Characteristic Derivation ® Type 1	Common Settings for Market Risk and ALM ® Characteristics and Characteristic Values ® Characteristic Derivation for Non-Integrated Financial Object Maintenance (Type 1) ® Define Derivation Strategy
Type 2	Master Data ® Characteristic Derivation ® Type 2	Common Settings for Market Risk and ALM ® Automatic Integration of Financial Objects

The following types of derivation are carried out by the system according to the context:

·       Financial object maintenance

Type 1 derivation is always used. If financial object integration is active, no derivation is carried out at all for each active transaction category.

·       External data transfer

Type 1 derivation type is always used for the transfer of financial objects. Instead of transferring objects by EDT, you can also generate them using a generation report. In this case, type 2 derivation is used. Generation reports can be used for loans, class positions in securities accounts, class position in futures accounts and money market/foreign exchange/derivative transactions. You find generation reports by choosing the following menu in Market Risk Analysis or ALM: Tools ® Reorganization Tools ® Financial Object Integration. Under Tools ® Reorganization Tools you can also find reports for changing financial objects.

·       Mass processing of financial objects

Type 1 derivation is always used. In the selection screen, those transactions are hidden for which financial object integration is active. However, by choosing Selection using financial objects, you can specify that type 1 derivation is used for all transactions.

Procedure

...

      1.      Select a derivation step and choose  Change rule entries.

The system displays the screen where you maintain the rule entries.

      2.      Make the changes required and choose  Save.

Result

You have changed the derivation of characteristic values.
