The interest accruals on our variable rate loans that have had a master index rate change are not calculating correctly when backdating or making adjustments over the index rate changes. For example, our master indices have changed effective 4/1, 7/1, 8/1, and 10/1 and when we backdate over those dates and make a rate change to a loan the accruals are incorrect. The show work option in LNIN 8 does not tie back to the correct accrual calculation. We are having to calculate manually all adjustments after the first rate is backdated. We have submitted a case to JHA and our CR (Connie Messer) suggested I check the Forum and see if any other users have experienced the same issue.
