OPSF(i) Modify Installment Terms

When using OPSF(i) Modify Installment Terms to set installments for AR Direct Debits, we experience random errors, where the actual balance of the total transaction amount outstanding changes.

So for example, an amount of £245.00, over a 9 month period, would be set as 8 installments at £27.22 and 1 installment at £27.24 and in the majority of cases this is what happens. But in random cases, when using the same Installment term, it sets the installments as 9 at £27.22 (£244.98) and reduces the actual balance outstanding from £245.00 to £244.98. This can only be amended by a datafix.

Has anyone else experienced and resolved this?
