Derivation type: Derivation rule

Derivation type “Derivation rule” works the following way: IF x THEN y.

Scenario: Depending on Product Groups different Profit Centers are assigned.

IMG -> Financial Supply Chain Management -> Treasury and Risk Management -> Transaction Manager -> General Settings -> Accounting -> Link to Other Accounting Components -> Additional Account Assignments -> Define Derivation of Additional Account Assignments (tr. TPM_DERIVE_ACCNT)

In general screen of derivation press “Create step” button or F5.

Select “Derivation rule” step.

Enter Source field – PRODUCT_GROUP “product group”.

Target fields – PRCTR “Profit center”

For your purposes you can use other fields

And press “Maintain Rule Values”.

Enter data from scenario table into Derivation rule.

One of the usefull things is we can use Source fields intervals – button when you create Derivaton rules.

Example: Depending on Amount in Nominal Currency and Nominal Currency we assign Financial Transaction Type to newly created transaction from external systems.

IMG -> Financial Supply Chain Management -> Treasury and Risk Management -> Transaction Manager -> General Settings -> Transaction Management -> External Link -> Define Mapping for Spot Exchange and Forward Exchange Transactions (tr. FTR_XI_MAP_FXLEG)

Let’s get back to our first scenario about Profit centers. We are not using Conditions, so our derivation step will be executed always.

On “Attributes” tab we can define additional parameters: it’s up to you to use this attributes.

• Issue error message if no value found

You can choose attribute to specify for each derivation step whether an error message should appear if no target values are found. For derivation rules, this option is automatically set as the default setting. If you do not want to maintain derivation rule values for every possible combination of source values, you should deactivate this error message display.

• It should be possible to maintain rule values using the validity date

If you activate this attribute, you can then make derivation rule entries for rules that have a “valid from” date.

• Step ID for Direct Call

This attribute is not required in general. It is only useful if you program, for example, a batch input for the data input transaction KEDE and want to directly access maintenance for a specific rule. To activate this attribute, right from general screen of Derivation choose “Goto -> Direct call using step ID”. You can then enter one of the available step IDs.

The derivation step is ready. Save it.

Don’t forget to Test it Derivation: Test your derivation steps.
