Steps to Reproduce

Root Cause
A defect in Pegasystems’ code or rules. The issue occurs as the Dataset rule in the associated class already exists and the name of the association rule does not match the case of the existing Dataset name. The issue pertains to upgradation as the associated Dataset rules and Association rules are created in the previous Pega Marketing version.
Resolution
Perform the following local-change:
- Delete the existing Datasets
- Save the Manage Data Relationship landing page
