Write Downs in Bill Prep - Using Action and the Write Up/Down function

You are probably getting confused with where you can use the minus. It is used only in the Percentage of Original field or the Percentage of Bill field.  (If you do put a - or negative number in the dollar field  - Orion will assume you want to make the bill zero and that is why it is zeroing out the bill amount fields because Orion does not allow a negative bill).

If you want to write up or write down a bill to a certain number for Fees, you put the total amount you want to bill for the Fees in the Dollar Value field. 

If you want to do a percentage write down you put in minus   -10 for a "write down of 10 percent" in the Percentage of original field. 

If you want to do a percentage write up you put in a 10  for a "write up of 10 percent." 

Note that this only affects the transactions you have specifically selected.
