Sorry about the spelling in the above post.
I have removed the Master Calendar table in the scema (first attached image) in case the lack of a link was an issue. There is only one table now in my schema, which I can Preview in the schema view, and confirm that it contains data.
Still nothing appears in my Chart/Table object, either when filters are selected, or no filters selected.
Any ideas of where to start looking would be greatly appreciated. I don't really want to pull my SQL extract back to 1 or 2 coulmns, but if this is the only way I can get data to view, and slowly add columns to the extract, then I guess that's what I'll have to do. Anywhere else obvious to look first?
I'm guessing you've created a chart (pivot or straight table) and haven't added an expression, but only dimensions. If that's so then there won't be anything to display. You'll need to add an expression too.
In a table box you can only add fields and no expressions. Table boxes are nice for simply displaying a table of some fields. So if you only want a table showing a couple of fields you can use a table box.
