Sales Order Header Level Hold using Extension

Summary:

Hi,

Looking for some help on groovy script to apply Sales order Header HOLD.

I see the below script, but that is to apply at Line level. Appreciate if someone can share HEADER level HOLD code. Thank you!

************************************************************************************

def lines = header.getAttribute("Lines");

while (lines.hasNext()) {
  def line = lines.next();

  // Make sure the ordered quantity is greater than 10.
  BigDecimal qty = line.getAttribute("OrderedQuantity");
  if (qty.compareTo(new BigDecimal(10)) > 0) {
    if (canApplyHold(line, "DOO_RSRV")) {
      debug("Applying hold");
      def hold = line.applyHold("DOO_RSRV"); // Create a hold and use the DOO_RSRV hold code.
      // Display text that explains what we're doing.
      hold.setAttribute("HoldComments", "We're holding this line so we can manually review and approve it.");
