Previously, the total sales tax calculated for an invoice during invoice entry was prorated across all invoice lines based on each line's dollar value. These prorated sales tax values were then written to the Summary Bill file, FMY, and Item Detail Activity file, FMZ, during the Sales Journal update.  Proration of sales tax resulted in less than precise reporting if items on the invoice were split shipped to locations that were in different taxing jurisdictions.

Proration is no longer used as the method for calculating the sales tax for a particular line item.   Instead, the invoice entry lines file, ART, and the associated parallel file, AZT, have been enhanced to enable storage of the actual taxable sale amounts as well as the respective actual sales tax calculated for each invoice line.  In addition, the state, county and other segments are stored as separate fields.   These calculated sales tax values flow through to the Summary Bill and Item Detail Activity files for each invoice line, greatly enhancing the accuracy of your Summary Billing and other Print Management Reporting.
