I am creating a printable company directory. I have a SOAP Service query that pulls everyone's data from the search service.
The query returns all the results I want.
I have enabled the "Sort & Filter on Headers" option in SP Designer so that users can filter the list by office location, or department.
Sort works perfectly, however I get a "This column type cannot be filtered" error when I try to filter.
The columns that I am trying to filter are single line, text fields with no multiple values.
I have no idea why I cannot filter this.
This is all in SharePoint 2010.
Thanks for your help.
