me again!
I'm getting this error in a CDS View in which I'm using a 'UNION ALL' and I can't figure out why I'm getting it.
I have the same number of fields in both selection lists (that is the Projection List, right?) and their types are all the same. The help says you don't have to call them the same thing but I have anyway.
Although the fields are of the same type, they come from different tables - that can't be the reason surely?
I've even debugged this and taken a look at the xml but that hasn't thrown up anything.
Any ideas please?
Thanks again,
Malcolm.
