A/P Voucher Information
In Purchasing, the PST/GST records are created when the A/P voucher is generated. The system does not alter these records, regardless of changes to the transaction in A/P or G/L.
If you enter vouchers or adjustments directly in A/P (not from Purchasing), the PST/GST records are created, based on the values in the special tax fields in the G/L distributions. When you post the manual vouchers, the tax records are created.
The PST/GST Taxable column shows only the value of goods that apply to the PST/GST code being reported. The value in the Voucher Total column includes all lines, charges, freight, and taxes on the document.
Because of the method in which voucher history is maintained, when you make adjustments to pre-vouchered amounts, the records are stored under the same voucher number, and the original voucher total is updated. In this situation, independent tax records are maintained under the separate PST/GST Taxable, but the Voucher Total shows the same amount. Therefore, because the column would double count, the Voucher Total column does not contain a subtotal.
The PST/GST Taxable column is less accurate for vouchers than for invoices, because the vendor calculates the tax with the tax basis as estimated from the PST/GST codes stored with the PO.
