Dimensions aggregate is a summary of information by function, time periods, and the decision model. Integrated information reflects the lack of coordination between segments of one and the other subunits within the organization. This research is quantitative. This study uses analysis of causal relationships, that is how one variable affects changes in other variables. To analyze the data, this study uses analysis of Structural Equation Modeling (SEM) approach Partial Least Square (PLS).In data processing using software Warp PLS. The results showed that the Accounting Information Systems Management is broadscope, timeliness, integrated, and the aggregate effect on Managerial Performance is measured using an instrument of self-rating which is reflected in four indicators, namely increased revenue, cost savings, improved customer satisfaction and increased asset utilization.
