Mapping a single DT attribute with multiple CT attributes

You can map a single attribute in the DT to multiple values in the CT. A single DT reference attribute is mapped to three different attributes in CT in the example shown below.

{
            "copyFromDT": "configuration/entityTypes/HCO/attributes/ClassofTradeN/attributes/FacilityType",
            "copyToCT": [
              "configuration/entityTypes/HCO/attributes/ClassofTradeN/attributes/FacilityType",
              "configuration/entityTypes/HCO/attributes/ClassofTradeN/attributes/AccountType",
              "configuration/entityTypes/HCO/attributes/AccountType"
            ]
}
