You can use the Impact Analysis tool to generate a report that identifies the procedures that access a specific Master File or field within a Master File. This tool helps you analyze the potential impact of modifying or deleting Master Files or fields. The Impact Analysis tool enables you to analyze data, control search criteria, save reports, and interactively open and edit procedures based on search results.
Impact Analysis searches Business Views in addition to FOCUS procedures. This enables you to see if changes in the original Master File will impact fields used in the Business View.
For more information about Business Views, see Creating Business Views.
