Enterprise Resource Planning (ERP) and Enterprise Systems (ES) have been in Information Systems (IS) researchers' and practitioners' focus for more than ten years. Yet problems with ERP implementation projects get exposed to the public eye constantly. This makes one marvel why so. In this paper, the authors will take a retrospective look at ERP research and identify the ERP research themes from two main information systems conferences, ECIS and ICIS, in this millennium. The analysis shows not only the prominence of ERP implementation research, but that other themes have been studied only sporadically and unsystematically. This urges for more ERP research with a broader focus. They then compare these findings with the conference tracks and discuss the role of tracks and gatekeepers in this phenomenon.
