Hi @Venky Kshatriy2 ,

Yes, you can use a for loop in an onSubmit client script to get values from a Multi Row Variable Set (MRVS) and send them to a script include for further processing.

 

Updated Client Script

function onSubmit() {
    // Prevent form from submitting
    if (g_scratchpad.isFormValid) {
        return true;
    }
    var actionName = g_form.getActionName();
    var ga = new GlideAjax('YourScriptIncludeName');
    var mrvsValues = []; // Array to hold MRVS values
    // Loop MRVS rows and collect values
    var mrvs = g_form.getValue('multi_row_variable_set_name');
    var mrvsLength = mrvs.length;
    for (var i = 0; i < mrvsLength; i++) {
        var rowSysId = mrvs[i].sys_id;
        // Collect your desired MRVS values here, e.g., mrvs[i].variable_name
        mrvsValues.push(mrvs[i].variable_name);
    }
    ga.addParam('sysparm_name', 'yourFunctionName');
    ga.addParam('sysparm_mrvsValues', JSON.stringify(mrvsValues));

    ga.getXMLAnswer(function(response) {
        var answer = response.responseXML.documentElement.getAttribute("answer");
        var highestValue = JSON.parse(answer);// script include returns a JSON object
        g_form.setValue('your_variable_name', highestValue);
        g_scratchpad.isFormValid = true;
        g_form.submit(actionName);
    });

    return false;// prevent default form submission
}

 

Script Include should be like this-

var YourScriptIncludeName = Class.create();
YourScriptIncludeName.prototype = Object.extendsObject(AbstractAjaxProcessor, {
    yourFunctionName: function() {
        var mrvsValues = JSON.parse(this.getParameter('sysparm_mrvsValues'));
        var highestValue = this._getHighestValue(mrvsValues);
        return JSON.stringify(highestValue); // Return the highest value as a JSON string
    },
    
    _getHighestValue: function(values) {
        var highest = values[0];
        for (var i = 1; i < values.length; i++) {
            if (values[i] > highest) {
                highest = values[i];
            }
        }
        return highest;
    }
});
