Survivorship Configuration – Tie-breaker for Same Weight Sources Using Most Recent Update Date

  • 1.  Survivorship Configuration – Tie-breaker for Same Weight Sources Using Most Recent Update Date

    Hello Team,

    We have a survivorship configuration requirement where multiple source systems have equal weights, for example:

    • Source A– 0.9

    • Source B– 0.9

    • Source C– 0.8

    • Source  D– 0.8

    Our business requirement is:

    ✔ When two sources have the same weight (e.g. Source A and Source B at 0.9), the most recently updated record value should survive.

    We configured survivorship rules with:

    1. Source System Priority

    2. LUD as Fallback

    However, Reltio seems to pick the first occurrence for SRC_SYS order , and the Most Recent Updated strategy does not act as a tiebreaker within source systems of same weight.

    Any recommended approaches to address this use case within existing configuration capabilities? 

    Has anyone implemented a "Highest Weight with Most Recent Updated as tiebreaker" in Reltio?

    Thanks in Advance.

    Regards,

    Rohini Arunachalam

    Hi Rohini,

    SRC_SYS doesn't allow specifying sources with the same priority in sourceUriOrder. However, in the sources section of L3, every source has a priority property. You can set it for listed sources as some equal value, and do not specify sourceUriOrder.
