A/R write-off cause VAT entry to be reversed

Hi Community -

We have some invoices generated in A/R (via Sales Update) that are prepaid invoices (a credit line is entered on Sales order for the prepayment to zero out the invoice). The invoices include VAT. Sometimes there are penny rounding differences when the A/R Invoice is process through Sales Update that are subsequently written off. When we use the Cash Application program to write off the amounts, the system is also writing off the entire VAT amount. Is there a way to prevent this from happening?

We are on JDE 9.1
