Survivorship Rules and OV Calculator

  • Why do I see multiple attribute values surviving rather than just one value?
  • Why does the Reltio crosswalk value survives and ignores all other values in one case, but that doesn't happen in another case?
  • Why is my update attribute value being added using LUD (or Recency) survivorship rather than being overridden?
  • Why a specific attribute type is getting it's values ignored?
  • Why do I have two OV attribute values when it should be only one based on the fallback strategery of LUD?
  • Why am I getting two different values - one OV value for the MDM and one OV value in GBQ or Qubole?
  • Why is the nested attribute value using singleValueByCrosswalkSources being overridden when the aggregation has been applied?
  • Why do I see two different values for an attribute for the same source on a crosswalk when I am using LUD survivorship?
  • How does order of data load affect the OV?
