Analyzing variances for a time period or for a series of time periods can indicate a need to update standard costs. Use the Standard cost variance analysisreport to view an item's production variances and purchase price variances over a specified time period and intervals, such as monthly intervals to view trends. The report displays an item's current standard cost and suggests a new standard cost based on variances. Selectively report information based on selection criteria, such as the site or item number.
