We have an adjustment to a Pledge payment which has four splits. The Solicitors window (the window opened by selecting "Solicitors" from the Revenue menu) shows all four splits with their respective amounts, totaling the payment amount which matches the amount shown in the batch window. When we validate, we get the message, "The amount credited to a single solicitor cannot be greater than the amount for the revenue the solicitor credit applies to."
