Duplicate_Value: duplicate value found when building unique index

Duplicate_Value: duplicate value found when building unique index

Duplicate_Value: duplicate value found when building unique index is due to setting a field Unique and that field has duplicate values in the existing records.

Whenever a field is set to Unique, Salesforce will index that field. During that time, if duplicate values are found on that object, we will face this issue.

Cheers!!!
