Hi All,

I have a requirement where I need to create 2 variables first is simple variable named test stockroom which is refeering to alm_stockroom table and second variable is MVRS test2 which includes one variable test asset  that is referring to alm_asset table and as per the requirement the second variable value(multi row variable) will be dependent on the first variable value selected that means if I select test stockroom as ABC value then in the multirow varaible set variable in test asset i can see the only the asset related to ABC stockroom. Could anyone please suggest how to acheive this?

Hi @Nitesh Kumar5 ,

 

Catalog Client Script:

function onChange(control, oldValue, newValue, isLoading) {
    if (isLoading || newValue == '') {
        return;
    }
    
    // Make an AJAX call to get the filtered assets
    var ga = new GlideAjax('GetAssetsByStockroom');
    ga.addParam('sysparm_name', 'getAssets');
    ga.addParam('sysparm_stockroom', newValue);
    ga.getXMLAnswer(function(response) {
        var assetList = response.split(',');
        var mvrs = g_form.getValue('mvrs_test2');
        for (var i = 0; i < mvrs.length; i++) {
            var row = mvrs[i];
            var test_asset = row.getValue('test_asset');
            g_form.clearOptions('test_asset');
            g_form.addOption('test_asset', '', '-- None --');
            for (var j = 0; j < assetList.length; j++) {
                g_form.addOption('test_asset', assetList[j], assetList[j]);
            }
        }
    });
}

 

Script Include:

var GetAssetsByStockroom = Class.create();
GetAssetsByStockroom.prototype = Object.extendsObject(AbstractAjaxProcessor, {
    getAssets: function() {
        var stockroom = this.getParameter('sysparm_stockroom');
        var assetList = [];
        var gr = new GlideRecord('alm_asset');
        gr.addQuery('stockroom', stockroom);
        gr.query();
        while (gr.next()) {
            assetList.push(gr.getValue('sys_id') + ',' + gr.getValue('name'));
        }
        return assetList.join(',');
    }
});
