Here is a brief description on BRF...
TheBRF isa Runtime and Maintenance Environment for the Processing, Implementation and Configuration of Technical and Business Rules.
An SAP Application using BRF raises BRF-Events
��To eachBRF-Event, a number of Rules can be assigned.
��A Rule works like: If<booleanExpression> then<Actions>
��An Expression is an object that returns a result.
��Expressions may be nested.
��Usually, the result type is primitive (C, N, B, I, ...)
��An Action is an object, that acts on another(usually non-BRF) object.
��Actions may use Expressions as Parameters.
Events may be considered the „entrypoint/gateway“ to Rule Evaluation and Execution in BRF
��Events are implemented at specific points within a business process–e.g.: when a document is stored, when a payment is transferred etc.
��An Event is associated with one or more „rules“ which wil be executed when the Event is triggered
��Triggering an Event can be done via coding
��Events can define the context:
��E.g. crm event contextcrmt_brf_event_contex
BRF Expressions
��Expressions are BRF objects that return a definite result
��Boolean Expressions form the „IF“ part of the Rule
��Expressions can be e.g. of the following types:
•Constant
•Fieldof a Structure(DataSource)
•BooleanThree-operandArithmetic
•SAP Formula(as usedin BADI implementations)
BRF Actions
��Actions are BRF objects that start some activity as part of Rule Execution
��They form the „THEN“ part of the Rule
��Standard BRF Actions can be of the following types:
•ExecuteFunctionModule / Method
��Actions are usually application specific.
For example, some Actions in FS are:•Start Workflow/RaiseBOR-Event •Status change •Trigger BRF Event • Message into the CRM Log
BRF Rulesets
Definition of Rule Set:The rule set concept offers the option of grouping rules that are connected in the business sense, but distributed over several events, and then activatingor deactivating them jointly.
