Withholding tax (WHT) base amount wronglyg exempted - wring withholding tax is calculated

[linuspts06]

Hi Experts,

We have an issue with withholding tax exception, which I do not see on the platform. Request your input ASAP.

Extended withholding tax is not active in our system.

WHT Ctry is US and base country is AU.

in the WHT Code there it is selected "WHT posting with payment"

If I post Invoice with amount 12014.80 AUD, system is exempting 0.80 and at the time of Invoice posting.

Also it exempts the decimal portion of the WHT at the time of payment, irrespective of the decimal amount.

Example Invoice posted - vendor amount 12014.80

(in the invoice, WHT exempted 0.80 --> so base amount 12,014.00)

WHT rate is 5%, so 5% of 12014 = 600.70 AUD.

But during payment, it calculated only 600 AUD and exempted 0.70 instead of paying exact amount or rounding to 601.00.

I have traced substitution during posting invoice and payment, there is no EXIT triggered.

Please help on this.

Thanks in advance
