After creating a campaign, you may want to add additional vendors that were missed. Here's how to do that.
Go to the "Campaigns" tab in the accruals dashboard. Then, navigate to the campaign detail page by either clicking on the campaign number or by clicking on the view icon to the right of the grid.
From the campaign detail page, click on the icon at the top right.
This will bring you back to the campaign creation page where you can then add more vendors to the campaign. Once you've selected the additional vendors, click the "Submit" button at the bottom of the page.
