The BRMS (Business Rule Management System) connector enables you to use SAP Netweaver BRM or any other external rule engine with BRFplus.

Depending on the connection type (Netweaver BRM or External) the expression uses the appropriate function module to invoke the external rule engine. The expression allows you to specify the signature for the call based on the available vocabulary. Once the signature is defined, you can export metadata associated with the call as an XML schema.

The XML schema includes information about the input data objects, texts, and documentation associated with the data objects and return parameters that the rule engine should populate.

When defining the expression, you can also specify any parameters specific to the rules engine being used. For a call to Netweaver BRM the two parameters, project and rule set, should be populated. While the call is being executed, BRFplus creates an XML document corresponding to the above XML schema and passes it to the other rules engine.
