Projects with high complexity have a high risk of increasing construction costs, data accuracy is needed regarding cost control so that these problems do not occur. SAP S/4 HANA module Project System (PS) is an ERP system-based application that contains data ranging from planning, procurement, control, and payment. Previously, there was no study on the implementation of SAP S/4 HANA specifically for the PS module on infrastructure projects. It is necessary to analyze the implementation of the SAP S/4 HANA PS module on data accuracy as a net benefit. This study aims to analyze the factors that influence the implementation of the SAP S/4 HANA PS module on data accuracy as net benefit in infrastructure projects. This research method used descriptive statistical methods, causal correlation analysis and factor analysis. Data collection techniques were carried out by expert validation and questionnaires given to the infrastructure project team using the SAP S/4 HANA PS module. The results showed that the ease of use, the speed of accessing information (system quality), data reliability and data validity (information quality), had a positive effect on data accuracy (net benefit). This research can be used to improve data accuracy and report quality with SAP PS module.
