# Which Team Foundation Server (TFS)/Azure DevOps fields are supported by OpsHub Integration Manager f

### Description

Team Foundation Server (TFS)/Azure DevOps fields contain Read-Only fields and Writable fields. Not all of these fields are supported for synchronization.

### Solution

* All the fields that are writeable from the User Interface can also be writeable from <code class="expression">space.vars.SITENAME</code>. It can be an HTML, Text, User, Numeric, Boolean, or Lookup field.
* Few fields such as ID, Watermark, etc. are Read-Only fields. These fields cannot be writeable but their field values can be readable by <code class="expression">space.vars.SITENAME</code>. Refer [Team Foundation Server - Common](/opstech-docs/7.223/connectors/azure-devops.md#known-behaviors--limitations) section's step 3 to get list of Read-Only fields.

{% if "OpsHub Integration Manager" === space.vars.SITENAME %}
\* In Team Foundation Server (TFS)/Azure DevOps, there are fields such as Changed By, Changed Date for which auto-generated values can be overwritten. For this, By-Pass Rule should be enabled during system configuration. Refer table under \[Team Foundation Server - Common]\(../../../connectors/azure-devops.md#known-behaviors--limitations) section to check which all fields are supported with and without By-Pass with different API option.
