Product volume variance and Other Costing Related Variances

Solution	Product volume variance Few  of the inputs required for calculation are not maintained in the system. If you wish to calculate this at each FG Item level, you would require to maintain Budgeted Production Volumes. Production volume variance = (Actual Production - Budgeted Production) x Budgeted Overhead Rate	I advise to generate these reports outside ERP by taking information from ERP for a month or two initially. Then see how to automate them using OBIE by looking at actual data flowing from the system & capturing the missed information in the system at appropriate places.
Solution	Other Costing Related Variances These as per my understanding are: -          Labor Cost Variance (for Renata, this is like Variable OH) -          Overheads Variance (Variable, Fixed) o   Variable (Expenditure, Efficiency) o   Fixed (Expenditure, Volume) If you are comfortable, over a period of time 6-12 months after go-live, you can extend the variance analysis to Sales Margin, Selling & Distribution cost variance as well.
