Generally, publishing to a report server running in SharePoint integrated mode,

we need to specify the TargetServerURL property to a URL of a SharePoint top-level site or subsite.

For example, http://<servername&gt;, http://<servername/<site&gt; or http://<servername>/<site>/<subsite&gt;.

And also specify the TargetReportFolder to a URL of SharePoint library to the.

For example, http://<servername>/<site>/Documents/MyFolder.

However, if it still doesn’t work. Please let me know.
