I've entered a pledge. The donor has only paid part of their first payment and plans to make a payment for the balance in a month. However, the pledge bumped the overdue amount to the following year's pledge. And it appears that I cannot enter a payment against the first year's pledge now.
Click to expand the pledge payment schedule and then click edit on the expected installment set up for next year - you can change the date back to the current year.
Unless you are dealing with multi-year pledges, consider creating them with a single installment to occur every one day - in this way, the system will transfer the remaining balance as being due the following day as opposed to the following year.
Hope this helps, Tamar
