### Configuring Input Fields to Write Data Back to Records
Input fields include the ability to define a location in which signer supplied data can be written back to the Salesforce generating record.
{% hint style="info" %}
Signature and Initials input fields do no support write-backs to records. Data write-backs only apply updates to and from [**e-signature requests that are initiated from a specific record**.](https://help.sdocs.com/sdocs/~/revisions/tQryHJcKs5a9X6UOG4oU/s-docs-e-signature/launch-e-signature-requests-from-a-salesforce-record)
{% endhint %}
To configure a data write-back:
Click on the input field in the template body to lauch the field configuration menu.
Navigate to the **Assignment** section.
Select the field from the drop-down menu that will receive the signer-provied information.
Upon successful submission and processing of the signature request, the provided information will update the appropriate record automatically.
