Understanding Final Tax Calculation

If an invoice requires India GST calculation, the Finalization process (BIIVC000) calls the Tax Calculation common process and updates the invoice total amounts for those lines with no associated excise invoice number.

When the Finalization process calculates final taxes, all information that the Tax Calculation process requires must be available and saved in the appropriate PeopleSoft Billing tables. If this information is not available, the Finalization process marks the affected invoices in error, and requires you to provide the necessary information before the invoices can be finalized.

Note:

If a bill line has no associated excise invoice number and amount, and the GST applicability flag is defined as no, the Finalization process does not include the bill line in GST calculation.
