What type of field is that? Different field types have different filter options. Also, what's your data source?
Is the field a group or a set? If so, these types of fields are not meant to have Wildcard filters. This might be a good one to add to the Ideas section!
Thanks everyone, the data source is Oracle, and it's a standard String field. Not a group or a set.
The only reason I can think of is that it's on a map? But I don't see why that would matter.. Is this a bug maybe?
Can you post the workbook or a sample workbook (twbx files)?
