Actual costs distribution for asset route

Hi! Can anybody help?

We have the work order created for an asset route. Asset route consists of 3 asset numbers. For this work order PO receipt of OSP item was performed, transaction sum is 1000. After closing WO we see some transaction distributions. Actual costs of work order were distributed between asset numbers of asset route proportionally. But the sum of these transactions is 999,99. How can we get transaction for 0,01 value? Are where any ways for such setup?
