To remove duplicate values from an array obtained through GlideRecord, you can use JavaScript's Set object.

// Create a new Set object to store unique values
var uniqueValues = new Set();

// Iterate through the GlideRecord results
while (gr.next()) {
    // Get the value of the column you want to make unique
    var columnValue = gr.getValue('your_column_name_here');

    // Add the value to the Set (which automatically removes duplicates)
    uniqueValues.add(columnValue);
}

// Convert the Set back to an array
var uniqueArray = Array.from(uniqueValues);

• Set is a JavaScript object that stores unique values. By adding values to a Set, duplicates are automatically removed.
• Finally, you convert the Set back to an array using Array.from().

This way, uniqueArray will contain unique values extracted from the specified column in your GlideRecord results.

Hi @servicenow14710 ,

To find unique elements from an array & remove duplicate elements from an array. you have to use "Array Util'.

var arrayUtil = new ArrayUtil(); // API

Sample code:

var arrayUtil = new ArrayUtil(); //OR 'new global.ArrayUtil(); if from a scoped app;

var array1 = [“INC1###”, “INC2###”, “INC3###”, “INC4###”, “INC5###”];

gs.print(“Contains INC1###: ” + arrayUtil.contains(a1, “INC1##”)); //Contains a specified value 

gs.print(“unique values: ” + arrayUtil.unique(array1)); //Gets unique element.

 var array2 = [“INC1###”, “INC2###”, “INC7###”, “INC4###”, “INC4###”]; /Combines 2 arrays and gets unique values

gs.print(“Taking unique Value: ” + arrayUtil.union(array1, array2));
