Enterprise Resource Planning (ERP) systems, also called Enterprise Systems (ES), have received much attention from researchers and practitioners. Along with that many researches have underlined the pivotal role of knowledge management for enterprise system success. This research in progress paper explores articles published in 8 journals during recent 11 years for knowledge management instances across ES lifecycle and categorizes these processes according to each phase of ES and knowledge management lifecycle. Subsequently presents the further analysis about gaps in the research area and under-studied fields which warrant future research.
