Check this option to perform a partial write-off based on a write-off percent. When selected, the percentage specified in the FC Amount or FC Percentage field will be multiplied against the total remaining finance charge amount for the invoice to determine the dollar amount to be written off against each line. The write-off amount is then distributed beginning with line #1 and progressing to each successive line until the specified amount has been distributed in full. Remaining lines will be left untouched.

Do not check this option if you do not want to write off finance charges by percent and have the value applied as allowable beginning with line 1. Finance charges will be written off using one of the other methods.
