When you are working with opportunities, Salesbuildr automatically updates the opportunity stage and status based on the rules you have set under Admin, Quotes, Opportunity Settings.

To be able to use the won opportunity wizard you will need to keep the opportunity status active.

When you have run the won opportunity wizard and you close the opportunity, any linked line items on sales orders and charges will be set to status cancelled if you re-open the opportunity from Salesbuildr.

When this happens, You will need to manually change the status back to the requisite status.
