The HL7 Reference Field specifies the default HL7 field from which chart data is extracted. If a specific HL7 message template needs to override the setting configured here, assign a chart field override to the template.
Use the HL7 standard format to identify the field. For example, PV1.3.4 indicates that the value is in segment PV1, field 3, component 4.
To pull a single value from a specific instance of a repeating field, see Pulling Values from Repeating HL7 Fields.
