# How do I compose a message in a Sourcing event or questionnaire?

## Symptom

How do I contact the buyer about a Sourcing event or questionnaire that I am participating in?

## Resolution

There are two ways to send a message from a Sourcing event.

First option:

1. Access the event or questionnaire from the **Ariba Proposals and Questionnaires** page.
2. In the upper left corner, click **Event Messages**
3. Click **Compose Message**.
4. Enter your message and attach any files you need.
5. Click **Send**.

Second option:

1. Once in the Sourcing Event, locate the **Checklist**.
2. Click **Submit Response** > **Compose Message**.
3. Enter your message and attach any files you need.
4. Click **Send**.

## See Also

The buyer must configure the event to allow messages between the buyer project team and event participants. If the buyer does not allow messages, it is not possible to compose new messages or reply to existing ones.

Please note that SAP Support does not provide contact information for buyers.
