Change menuitem property through X++ AX2012

In a new requirement, I had to generate a URL based on the logged-in user using a new parameters table. The URL had to be opened from EP->EmployeeServices and hence it is a URLMenuItem I was not able to handle it through URLRedirection in C#.

What I decided to change the URL property of the menuitem through code. Below is the code:

private void leaveURL(Str60 encryptedUserName)
{
    Name        encryptedName;
    TreeNode    objTreeNode;
    objTreeNode = TreeNode::findNode(@"\Web\Web Menu Items\URLs\ALE_ESSLeave\");

    if (objTreeNode)
    {
        objTreeNode.AOTsetProperties("PROPERTIES\n URL  #" + 'http://' + HcmSharedParameters::find().ALE_ESS_IP + '/oasis/AX_ESS_Integration.aspx?U=' + encryptedUserName +'&C=' + HcmSharedParameters::find().ALE_LeaveEncryptedCode + "\n ENDPROPERTIES\n");
        objTreeNode.AOTsave();
    }
}
