Custom Numbers Compound Comparisons

Two compound comparisons are provided per custom number field, one where exact matches only are of interest, and one where the records being matched may contain differences. It is designed with the expectation that only one of these compound comparisons would be enabled, as per requirement.

The exact compound comparison contains only a single rule of an exact match. The other, fuzzy, compound comparison contains rules that cater for character transposition of digits, small absolute differences between the numbers and small percentage differences between the numbers.
