Match rule with specific source.

Question : 

Can we set filter conditions in a match rule to target specific source values within an entity for matching?

For example, if address data comes from Salesforce, Reltiocleanser, and SAP crosswalks merged into one entity, the match rule should exclude addresses from Reltiocleanser and SAP.

Answer : 

Yes, it is possible by configuring the filters to exclude values from undesired sources within the match rule. For instance, to exclude ReltioCleanser and SAP, you can define a filter that includes only the desired sources, such as Salesforce.

{
  "attribute": "configuration/entityTypes/Individual/attributes/Address",
  "useOvOnly": false,
  "filter": {
    "in": [
      {
        "uri": "configuration/sources/Salesforce"
      }
    ]
  } 
}
