Prepaymnet not using the GCT rate the invoice was paid at when appllied to Final Invoice

11.5.10.02

Hi all

A prepayment invoice was entered and paid with tax code "GCT" at 16.5%... The government change the tax code rate from 16.5 to 17.5%...This new tax code was created "GCT" at 17.5% while the other was end dated.

When the Final invoice was received the tax rate on it was 17.5%....however when the prepayment was applied and validated the Tax rate use for the taxable amount on the Prepayment distribution lines was 17.5% and not 16.5% that the prepayment was previously paid at...

Even though the invoice date of the final invoice is within the effective date range of the Tax code "GCT" at 17.5%, what can be done to ensure taxable prepayments that were made when the rate was 16.5% when they are applied the system uses the 16.5% on Final payment prepayment distribution lines when applied.
