Updating processing log for sales order header output

[Former Member]

I want to prevent a custom sales order confirmation from printing when the order has not been approved. When the user requests the form to print in the background, I want to update the processing log to have a red light and a message indicating the order has not been approved, so it cannot be printed. When I pass an error message to the protocol processing, the update is terminated and my changes to the sales order are lost. Is there a way to update the processing log, show the red light, and not get the hard error?

Thank you in advance.

Setting the return code after the protocol update did the trick.
