A data consistency analyzer identifies data inconsistencies proactively, providing insights into the financial, business, and technical impact to enable users to make decisions regarding resolution of the inconsistencies. The data consistency analyzer may provide additional insights such as criticality of inconsistencies. Data inconsistencies may be caused by configuration changes to master data. As described herein, data consistency is improved by keeping a constant watch on various master data changes which is one of the major sources towards causing inconsistency and taking necessary actions based on further assessments. Using master data change as initial lead, the inconsistencies would be identified that are not mere database or technical inconsistencies. Along with the primary option of inconsistency check based on master data change, additional options to scan the system based on overall run and run per selection, or application level specific checks will be provided.
