What is a duplicate case?

Duplicate cases are cases that have the same data and purpose. But having the same data alone doesn’t make a case duplicate.

The application has to ensure that it does not let duplicate cases undetected into the system.


A customer has created two orders that have the same products, and quantities. In this case, the second order might be a duplicate order. The application has to evaluate whether the second order is a duplicate, and flag it.

Pega Platform provides the ability to configure conditions that help detect duplicate cases.

How to detect duplicate cases

Pega Platform provides the search duplicate cases feature, which gives the ability to detect duplicate cases. This has to be added to the case flow as a step, and you then configure the conditions.

These are Basic conditions and Weighted conditions, which compare property values in the application to determine whether a case is a duplicate.

Basic conditions

Basic conditions are the required conditions that must match for a case to be considered duplicate.

Weighted conditions

Weighted conditions can be assigned a score and a threshold, and can be defined as the sum of all the weighted conditions.

A case is deemed duplicate when:

  • The basic conditions are matched, and
  • the Sum of the weighted conditions matches or exceeds the threshold value.
