You can set up the system to generate additional flows in transaction management automatically on the basis of an original flow. In this IMG step, you define the corresponding derivation procedures. In the next step, you assign rules to the derivation procedure that determine how one flow is generated from another.
If you want a derivation procedure to be applied when a transaction is entered, you must assign this derivation procedure to a business partner. To do this, choose Derived flows in business partner maintenance.
Derivation procedures can be used for defining fixed commission rates for a business partner, or for generating tax flows.
To define derivation procedures and rules, you must first define the original flow type and the derived flow types in Customizing by choosing Define Flow Types for Transaction.
You want to automatically generate the flows for interest income tax and refundable tax.
Define a derivation procedure e.g. "ZAST"
Define the following rules:
You can use these settings to generate flow type 0306 (interest income tax) at 25% of the incoming flow type 0870 (accrued interest). In a second step, you define flow type 0308 (reunification tax) at 5.5% of the outgoing flow type 0306 (interest income tax).
