Extending SAP NW DSM/BRFplus capabilities to non-SAP landscapes
Decision Service Accelerator (DSA) is an add-on that extends SAP NW DSM/BRFplus running on SAP NW/SAP ECC/SAP S4H into a multi-purpose, multi-platform and multi-language business rule management and execution platform to suit the entire organization. It allows for central creation and distribution of SAP business rules and decision services as executable packages onto non-SAP servers, devices, and platforms.DSA is based on mature SAP technologies (SAP NW DSM/BRFplus) and is developed in close collaboration with SAP’s development team in Germany.
High-level System Architecture
DSA is offered as a stand-alone or cloud solution to generate SAP BRFplus rules into other languages like Java, C#, C++, JavaScript, Python and so on. In the cloud solution, generation is based on a decision service/function which is extracted and transmitted to the cloud in an XML file. However, in the stand-alone version the rules are created on the clients’ preferred non-SAP systems with few manual configurations.
DSA supports all the core and complex features of SAP BRFplus.
A client API to invoke rules
Some callbacks and exits to plug in client specific logic (e.g. DB Lookup, call procedure)
Support for multiple platforms and runtimes (high flexibility)
The below high-level diagram shows how DSA is used to generate Java archive and deploy it into a non-SAP system. The same principle can be applied to languages other than Java as well.
The major advantage with DSA is, it simplifies your system’s architecture, without any additional hardware requirements and allows for more homogeneous, integrated business rules and decision service management. Without DSA, enterprises using SAP BRFplus may end up creating the same rules in non-SAP systems using another rule engine making the maintenance of the rules very challenging.
Work is in progress to extend DSA capabilities to HRF (HANA Rules Framework), so HRF rules can be executed on non-SAP systems as well.
