Abstract: A system automates the process of isolating incorrect, corrupt, or sensitive data and skipping duplicate records caused by violations of application business rules during report generation, for example. A data processor provides data for processing for incorporation in a report by, processing received report data to identify data objects in the report data likely to generate errors in preparation of a report based on the report data and providing validated report data by collating received report data and omitting identified data objects likely to generate errors. The data processor communicates the validated report data for storage in a repository for use in preparation of a report. An error data processor provides information indicating identified data objects in the report data likely to generate errors and a corresponding reason an individual data object is likely to cause an error.
