Dynamic Value Determination with BRFplus

Definition

You can use rules with the value determination type to model a context-dependent value determination.. We recommend using a corresponding rule for dependencies with one or more different configuration attributes.

We recommend using the field Standard Value for Attribute for standard values, which are values without dependencies..

The following table contains an overview of the characteristics of dynamic value determination using BRFplus:

Application usage	CD = Dynamic value determination
Reference object / cardinality	Attribute / 1:n
Versioned	Yes
Redefinition	Yes
Implementation class	CL_CRM_ISU_BRF_APPL_USAGE_CD
Inbound parameter	Variable according to the context generated
Return value	A value for attribute evaluation

Expression Type for Function: Decision Table

The following example only refers to the decision table expression type. Generate an entry in the decision table for every admissible value to ensure that the BRF application returns the required result:

Column	Description	Possible Entries
Condition
Such as attribute X	Attribute used as the basis for defining the field value
Boolean expression	Applies or does not apply
Result
ISURSLT	Return field value	Type-related to define the configuration parameter

Note Note

At runtime, the system processes the decision table again if the value of a context attribute in the condition columns in the decision table has changed.

End of the note.

Example

The product offers two durations of six or twelve months and the option of a price guarantee.

If you choose the price guarantee, you can only choose a twelve month duration.

The system creates a new rule for the attribute Duration. The Price Guarantee attribute is used as a context-dependent input parameter here. The decision table contains the following values in the example shown here:

Condition - Price guarantee	Result – Runtime
' ' (Option not selected)	6
'X' (Option selected)	12
