When translated reporting currency leaves an unexplained difference - how do I resolve this?

Summary:

Content (required):

In ARCS, reconciliations are completed in euros, these are then translated to the reporting currency of GBP. When a user enters a balance explanation/adjustment in euros, the functional currency unexplained difference is 0. When this is converted to GBP the reconciliation is left with a small unexplained difference (rounding). The user is unable to submit the reconciliation and gets an 'Unexplained difference must be 0' error.

How is this resolved so the user can submit the reconciliation?
