Federal Race Code should work the same in Data Mining as it does in Skybuild.
Skyward's explanation: Within Data Mining the Federal Race Description falls under a new folder that contains the Fed Race Code and Fed Race Description. This means that in data mining a separate line will be printed for each Federal Race that is selected for the student. If the Data Mining report is set up to be one line then it will repeat the fields as many times as needed for how many Fed Races apply to the student.
Skybuild is not set up in this manner to repeat the field multiple times for each Fed Race that applies to the student, it is a stand alone single field that does not repeat. The Fed Race Description is a single field and does not repeat, so if a student has more than one Federal Race the description will appear as Multi-Racial.
