This keyword lets you specify a value to see only out of balance transactions over a certain amount, or use the default value of 0.
MatchingTolerance=ToleranceValue
Replace ToleranceValue with a number that is less than 1 billion. The limit for this keyword is 999999999. For example:
MatchingTolerance=100
For example, if an Entity has an amount of 299 and the Partner has 200, the difference is 99. If the matching tolerance amount is 100 and the difference between the Entity and Partner is less than 100 as in this example, you can use the SuppressIfMatch keyword to have the system suppress the transaction because it is within the matching tolerance.
