Enterprise resource planning (ERP) systems are large modular enterprise applications intended for execution of majority of enterprise business processes with focus on transaction processing. However, the business processes often also require complex decision-making. Data processing logics is deemed as complex decision-making logics if it involves complex analytical calculations and requires domain specific knowledge. This paper reviews existing research on decision-making capabilities of ERP systems and identifies different approaches for integrating decision-making logics in ERP systems. This review leads to an initial framework for integration. This framework evaluates current solutions used in integration. The research findings suggest that decoupling of decision-making logics from ERP systems enables usage of advanced decision-making techniques for execution of decision intensive business processes in real-time though logical integration between decision-making components and busi ness processes should be improved.
