Match Rules

Match rules determine how matches are made.

Rules can be configured for tolerance ranges on dates and amounts, and adjustments can be made when variances exist.

Match Rule Types

The following matching rule types are supported:

  • 1 to 1
  • 1 to Many
  • Many to 1
  • Many to Many
  • Adjustment

Match Status for Match Rules

Each match rule can have a match status. The possible match statuses for match rules, other than Adjustment, are as follows

  • Suggested

  • Confirmed

  • Suggested (No Ambiguous)

    To add a rule with suggested matches that does not allow ambiguous results (multiple transactions that satisfy the rule conditions).

  • Confirmed (No Ambiguous)

    To add a rule with confirmed matches that does not allow ambiguous results (multiple transactions that satisfy the rule conditions).

  • Suggested Ambiguous*

  • Confirmed Ambiguous*

For rules of type Adjustment, the only match status supported is Suggested or Confirmed.

*For 1 to 1 Auto match rules, the match status Suggested Ambiguous and Confirmed Ambiguous can be used when there are a large number of ambiguous matches. These options ensure that all potential matches are found when auto match is run. However, they may impact matching performance.

Match Rule Conditions

A match rule condition determines which attributes must be matched together, and whether they must match exactly, or a tolerance is allowed.

Match rule conditions make it easier to define matching rules in multiple source match processes by defining the default relationship between attributes in the source system and subsystem.

Tolerance Limits

A tolerance limit specifies the permitted difference when matching two values in Transaction Matching. It can be expressed as a numerical value or a percentage.

For example, you specify a tolerance limit of -10 to +10 for Amount in the match rule. Then, the Amounts from the source system and subsystem are considered an exact match if their difference is equal to or less than 10. Consider a source system amount of 26000 and subsystem amount of 25990. These values are considered an exact match because the difference between them is 10, which is less than the specified tolerance of 10.
