Most exceptions have tolerances that check for an invoice amount greater than the expected amount. The Under Tax Variance invoice exception catches amounts that are less than the expected amount. How should I configure these tolerances?

Configure the absolute and percentage tolerances with a minus sign (-) to have the system look for values below a certain value or percentage.

For example, to allow values up to 3% below the expected tax and/or up to $10 below the expected tax, configure the exception as follows:

• Absolute Tolerance: -10
• Apply Absolute Tolerance To Difference: Yes
• Percentage Tolerance: -0.97

On an invoice with $100 expected tax, the absolute tolerance is met if the tax is at least $90, and the percentage tolerance is met if the tax is at least $97.
