SAP SuccessFactors HCM Suite

Reproducing the Issue

  1. Go in Admin Center;
  2. Search for Manage Picklist Migration Conflicts;
  3. In Validation Check & Merge tool page the error Geteway Timeout is being shown;


A certain pattern of picklist data causes in an issue in the match checking logic of the Merge tool, and results in an out-of-memory condition in the application. The configuration that causes the issue relates to when:

  • The parent picklist entries for the legacy picklist and the MDF picklist do not match;
  • A child picklist entry matches between a legacy picklist and a MDF picklist;
  • The matching child entries also have matching child picklist entries (grandchildren);



Our Engineering Team is improving Validation Check & Merge tool and a new version is being planned to be on the Q3 2019 release (b1908).
