Loading an ISI file with this option will load the ISI file and then running Remove ISI Duplicate Records on the resulting ISI file. In this context, a duplicate ISI record is an ISI record whose ISI unique ID has already appeared once in a given file. Two files will be created in the Data Manager panel, the original ISI file and a unique records ISI file.
For example, a temporay.isi file that contains 100 records where one of the record has 10 duplications. The ISI loader will return a temporary.isi file that contains 100 records and a '91 Unique ISI Records' file that contains 91 unique records.
Allows user to have the flexibility to use the original ISI file or the unique records ISI file. Be aware to use the original file for processing if you don't want to remove duplicate records from your ISI file.
