I am creating a project management site template. This template will be used to create PM subsites in our corporate PM site. In the subsite task list, I want to add a "Work Area" column that is a lookup to a list in the parent site, so that the work areas list needs only to be maintained in one place.

I have seen posts regarding adding WebParts to look at parent site lists, but nothing on how to add a parent site list as a lookup for a column.

Any and all help is appreciated.

Its not entirely clear for me from your description if we are talking sub sites or sub site collections.

If its just sub sites, like team sites under SITES managed path, you can map a normal lookup site column to point to the list in the root site of the site collection and add that column to your task list.

If your are working on different site collections you need to look for third party tools like Steve mentions.

If you define a Site Column and or Content Type at the parent site you can reuse that from the sub-sites. Here is a blog post I wrote about this topic.


There are third party companies where you can buy this functionality.

Or it's available free on codeplex: SharePoint Filtered Lookup Field
