i already make quotes and send to customer by email status was submitted. customer contact back and want some revision of quantity. click cancel and ammend to existing qyotation, we change numbers and after all we want to save this errors pop up.
how to change status to valid parameter?
Seems like an issue.
Can you go to Setup > Customize > Customize Form, select Quotation and add “Replied” as an option for status
