How to Perform XSUM Deduplication

Article #: Product: Version:

Summary

XSUM is a mainframe/JCL sort deduplication function that writes each first record with a unique key value to one target, and writes any subsequent duplicate-keyed records to another target.

This functionality can be achieved in DMExpress using cross-record logic via conditions and user defined values in a sort task.

Resolution

The attached example demonstrates how to implement the XSUM function in DMExpress.
