Header CHARGES does not balance:

This error indicates that the sum of the Subtotal, Shipping, Sales Tax and Discount fields do not agree with the Charges field in the Invoice Header (these fields should balance internally).  To correct this error the operator should make sure that the individual amounts in the header are correct (that the subtotal matches the extended value of the invoice line items, the sales tax amounts in the line items match the header, the payments and adjustments totals, match activity for the invoice in the journal entry file, etc.) and use the Limited Invoice Editor to adjust the Charges field in the invoice to the correct amount.
