Autopopulate SR details in catalog

[alt]

I have to create a catalog where if type_of_request is Shopping & Deployment and the requestor will choose the SR number on the variable field: indicate_the_assessment_quotation_ticket it should autopopulate the details of SR

Hi @alt ,
The sysparm_id is expecting the sysid of the sc_req_item.

assuming the variable indicate_the_assessment_quotation_ticket is referencing to sc_req_item 

you should update the line no:5 in the client script as you are passing a constant value "indicate_the_assessment_quotation_ticket" and not a sysid that the script is expecting

function onChange(control, oldValue, newValue, isLoading) {
    var req_for = g_form.getValue('sc_req_item');
    var ga = new GlideAjax('GetVariableDetails');
    ga.addParam('sysparm_name', 'GetVariableDetails');
    ga.addParam('sysparm_id', g_form.getValue('indicate_the_assessment_quotation_ticket'));
    ga.getXML(RequestorParse);

    function RequestorParse(response) {
        var answerXML = response.responseXML.documentElement.getAttribute('answer');
        if (answerXML) {
            g_form.addInfoMessage("Answer XML: " + answerXML);

            var reqItemDetails = JSON.parse(answerXML);
            g_form.addInfoMessage("Parsed Details: " + JSON.stringify(reqItemDetails));

            if (reqItemDetails) {
                g_form.setValue('dmr_cost_center', reqItemDetails.dmr_cost_center || "");
                g_form.setValue('cost_center', reqItemDetails.cost_center || "");
                g_form.setValue('dmr_department', reqItemDetails.dmr_department || "");
                g_form.setValue('department', reqItemDetails.department || "");
                g_form.setValue('dmr_location', reqItemDetails.dmr_location || "");
                g_form.setValue('location', reqItemDetails.location || "");
                g_form.setValue('meeting_room_name_or_number', reqItemDetails.meeting_room_name_or_number || "");
                g_form.setValue('purpose_of_installation', reqItemDetails.purpose_of_installation || "");
            } else {
                g_form.addErrorMessage("Parsed details are undefined.");
            }
        } else {
            g_form.addErrorMessage("Failed to get a valid response from the server.");
        }
    }
}
