Sourcing FAQ

Common Sourcing questions in the CSP.

What do I do if I have a sourcing issue?

Review the CSP Sourcing documentation. If you can't find the solution to your problem, contact sourcing.support@coupa.com.

How can I add details other than the price for each item?

Expand the item to see additional fields (for example, description) to enter details.

What browsers are supported?

Coupa Sourcing works best with Chrome.

How can I avoid losing my data if the browser times out?

Depending on the time you need to fill in your responses, your browser might time out. To avoid losing your responses, enter them offline by using the exported CSV file and import the file back into the event.

If you decide to fill in your responses online, make sure you save your changes frequently.

What is the size limit when uploading files?

The file size limit is 250 MB per upload. The recommended number of attachments is 20 - 40.

How can I contact an event organizer?

When an event organizer invites you to participate in an event, you receive an email that contains a link to the event and contact information for questions about the event or technical issues. See Participating in a Sourcing Event for more info.

After accessing the event, you can communicate with the event organizer through the Message Center on the bottom left.

Also, if you reply to the original email invite, your email is sent to the event organizer. 

How do I know if my response was submitted?

As a supplier, you can find out if your response was submitted from:

  • The flash message that indicates if the response went through.

  • The history at the bottom of the event page that indicates the total amount, response name, and the time the response was submitted.

How do I participate partially in an event?

Do not add a price if you do not want to participate in an event. However, if the field for the price is marked mandatory, you have to add a price.

What can I do if I submitted an incorrect bid in a reverse auction?

Ask the buyer to disqualify your incorrect bid. When the buyer disqualifies your bid, you can see a notification dialog.


The buyer can disqualify only your most recent bid.

If your new bid is less than 50% of your previous bid, you receive a warning dialog: "Your current bid is 50% or better than your previous bid. Are you sure you want to submit this bid?"

What do I do when the Submit button is grayed out?

If the event owner/creator has made changes to the event, you need to accept changes before you can submit your bid. The checkbox to accept changes is above the Submit button.

What happens when an event is being edited?

If a buyer is changing an event, the event closes for editing. If you want to view the event, you can see the following notifications: 

When the buyer finishes making changes and submits the event, a new revision of the event is created and you receive an email notification.

Clicking on the View Event button directs you to the revised event.

When you access the event, you have to accept the changes made by the buyer while entering your response. If you want to upload your response to the revised event using Excel, you have to export the Excel file and import it back with your response.

Why do I keep getting reminder emails?

You receive emails periodically reminding you that an event is about to end. If you haven't submitted your response, you need to respond within the last day of the event. If you have responded, ignore the reminder emails.

What is the best practice for entering responses?

Export to Excel, enter your response, and import the file. This helps you enter your responses offline.


If the event is closed for editing, the originally downloaded file cannot be uploaded and you have to download the file from the revised event.
