                }

            }

        }

        return Productversion.toString();

    },

Hi @Anish9515 

In your Client Script at this line.

var parts = multilineTextVersion.split(/\),/);

It should be like below, isn't it?

var parts = multilineTextVersion.split(",");

Cheers,

Tai Vu

My ouput in parts is Zip 21.x (Device, EN, Win),7-Zip 22.x (Device, EN, Win),7-Zip 16 (Device, EN, Win),7-Zip 18 (Device, EN, Win),7-Zip 15 (Device, EN, Win),7-Zip 19 (Device, EN, Win),7-Zip 23.x (Device, EN, Win)

I wanna separate Zip 21.x (Device, EN, Win)

7-Zip 22.x (Device, EN, Win) 
Like this 
In my scenario it doesn't work 

var parts = multilineTextVersion.split(",");

HI @Anish9515 ,
I trust you are doing great.
You can refer to below updated code for the same.

Client-Side Script

function onChange(control, oldValue, newValue, isLoading) {
    if (isLoading || newValue === '') return;

    var glideAjax = new GlideAjax('BISwCatDecomUtilAJAX');
    glideAjax.addParam('sysparm_name', 'getProductVersions');
    glideAjax.addParam('sysparm_sys_id', newValue);
    glideAjax.getXML(handleResponse);
}

function handleResponse(response) {
    try {
        var answer = response.responseXML.documentElement.getAttribute("answer");
        if (!answer) throw new Error("No response received from server");

        var productVersions = answer.split(/\),/);
        var display = productVersions.length > 1;

        g_form.setDisplay('sw_cat_item_removed', !display);
        g_form.setReadOnly('sw_cat_item_removed', !display);
    } catch (error) {
        console.error("Error in processing GlideAjax response:", error);
        // Handle the error appropriately
    }
}

Server-Side Script (BISwCatDecomUtilAJAX Script Include)

var BISwCatDecomUtilAJAX = Class.create();
BISwCatDecomUtilAJAX.prototype = Object.extendsObject(AbstractAjaxProcessor, {

    getProductVersions: function() {
        var softwareId = this.getParameter('sysparm_sys_id');
        var productVersions = this.fetchProductVersions(softwareId);
        return productVersions.join(',');
    },

    fetchProductVersions: function(softwareId) {
        var versions = [];
        var productQuery = new GlideRecord('u_biproductgroupingproduct');

        productQuery.addQuery('sys_id', softwareId);
        productQuery.query();

        while (productQuery.next()) {
            var versionQuery = new GlideRecord('u_biproductversion');
            versionQuery.addQuery('u_product_id', productQuery.u_product_id);
            versionQuery.addEncodedQuery('u_product_version_status=Active');
            versionQuery.query();

            while (versionQuery.next()) {
                versions.push(versionQuery.u_product_version_name.toString());
            }
        }

        return versions;
    },

    type: 'BISwCatDecomUtilAJAX'
});

 If I select a software product field that has only one version, it works fine, and if I select a software product field that has many versions, it works fine as well but i got java script console error i.e Error in processing GlideAjax response:

It's cause whenever software product keep changes in form level before submit javascript console error occurs
