During the final stage of a media campaign, when your customer accepts your proposal and ordered your campaign, you can create an order confirmation ready to be sent to your customer. The process of creating a order confirmation is the same as creating a proposal. But beforehand, you have to make a few changes to the media campaign's details.

Change Document Type

Double-click the document type in the media campaign's detail section. Then change the pick-list's values. Now continue like when you create a proposal: Click the Generate Document button to open the pdf.
