            dataType: 'json'
        })
        .done(function(data) {
            if (data.d) {
                clearDeductionPage();
                hideLoader();
                showNotification("Success!", "Deduction Detail Saved !", "notice", "br");
                callback(data);
            } else {
                    getRecentErrors(function(data) {
                    hideLoader();
                    showNotification("Error!", "Error in Saving Deduction Details !\n" + data.d.Message, "error", "br");
                });
            }
        })
