The Tolerance Check section of the Parameters sheet displays the values that affect the tolerance checks applied when you ran the report. It includes the commit tolerance, the materiality check, and reference field names specified at the Field Rule or Report Rule level.

For more information, see "Chapter 5: Working with Long/Short Positions." See the following figure.
