Taxes for ERS invoices are calculated using the tax settings for each receiver line, and the resulting tax is stored by line.

If the ERS Price List option in ERS Maintenance specifies a price for the supplier invoice that is different from the price used for the order, variances occur that affect the calculation of taxes. If you select the Recalculate Tax Details field in the ERS Processor window and any price variances have occurred, the tax is recalculated.

The ERS Invoice Date option determines the supplier invoice date set by ERS and the invoice date, and, therefore, the due date resulting from the application of the credit terms. The supplier invoice date is also the tax date used by ERS for tax calculation.

When fiscal receiving is activated, ERS creates supplier invoices with the same tax date and total amount as the confirmed legal (fiscal) document header.
