Question
The choice field and lookup field allow for multiple selections. I can't find that option for lookups to external content types. Is it possible to do this?
(I want to assign documents to one or more clients, using a clients list coming from CRM 2011 using ECTs.)
Solution
You can create a lookup column based on an external list, but you can't have multiple selections or bring in additional columns. This is a limitation of the external list data in SharePoint 2010.
See MSDN.
