User By mistake put Gst tax on Prepayment invoice:

Hi All Experts,

We have a Standard invoice with amount 51,000 and we apply two prepayments on it first one is 49,000 and other one is 2000. On prepayment amount 49,000 user wrongly put 17% Gst on line  rather then put this Gst tax on item line. After this 17% tax is calculated on 49000 with amount of 8330.

Remember this issue is only occurring on production. Not available on clone instance

Your helpful suggestion will  be highly appreciate.

Regards

AYAZ
