Sage X3 provides an inbuilt function to verify if there are any duplicate values in a series of variable or numeric expressions, alphanumeric expressions or dates.

The function used for this purpose is UNI.

If the series contain duplicate value(s), the UNI() will return the position of the duplicate value.

If there are no duplicate values, the UNI() will return 0.
