Why does LORAN require either paid, incurred, or outstanding amounts be calculated?

When mapping a file to be imported into LORAN, you may encounter the error, "One of paid, incurred, or outstanding amounts must be calculated".  

LORAN requires that Incurred Losses = Paid Losses + Outstanding Losses.  However, in some loss runs this is not always the case.  A typical example is where Incurred Losses are rounded to the nearest dollar, but the Paid Losses and Outstanding Losses are included to the penny.  To accommodate this, the system defaults to importing Paid Losses and Outstanding Losses and then computing Incurred Losses as the sum of the two.  For many loss runs, this is a redundant step as the Incurred Losses from the file are already equal to Paid plus Outstanding.

This warning is simply to inform you that you must allow the system to calculate one of the three amounts (Incurred, Paid, or Outstanding).  Typically we recommend sticking with the default of allowing LORAN to compute Incurred as Paid + Outstanding.
