Scientific Names are stored in a separate table than the Element Tracking record, therefore to change the Scientific Name associated with an Element Subnational Tracking record, the link between the two tables is changed, not the actual Scientific Name record.
In the EST record, click the Lookup icon next to the Scientific Name field within the Identifiers section.
Within the Search for Scientific Name dialog, Search for the desired Scientific Name.
From the Search Results section, select the desired record or
If the name is not found, click the New Record button at the bottom of the dialog to Create a Scientific Name record. After the Scientific Name record has been created, it will appear in the Search Results section of the still open Search for Scientific Name dialog.
Save the changes within the Subnational Element Tracking window.
NOTE: Do not edit the Scientific Name record itself. Doing so will alter the name wherever it is used. For example, if the same name is used for the Global Scientific Name and/or National Scientific Name, those will have been altered as well.
