The Process Guidance Help Link column type allows you to create a library of easily referenced Process Guidance e.g. pages in a wiki. When you create a new list item, all you need to do is add the filename of the page being referenced (e.g. page1.aspx).
Use of the Process Guidance Help Link column in non-BrightWork site collections is supported but is subject to license. Please contact your local BrightWork or SharePoint support contact if you are unsure of your BrightWork license status.
To add and setup the Process Guidance Help Link column:
If the location was a wiki or a document library on the same server, you would only have to provide a server-relative URL, e.g. /sites/mysite/Projects/ProjectA/wiki/Wiki%20Pages/.
You should ensure that all the relevant users have access to this location.
