Hi Dwain,I did have a go at your attempt, however if I want to be able to use this on a monthly basis i would have to do the manual insert statement every time??

Not sure what you mean by the manual insert as mine doesn't do any inserts.
I took your original code and embedded it in the first CTE. You should uncomment that and use it instead of the SELECT/UNION ALL SELECT query inside that CTE (you said that's what your query produced).
The rest should stand pretty much on its own.
My thought question: Have you ever been told that your query runs too fast?
My advice:
INDEXing a poor-performing query is like putting sugar on cat food. Yeah, it probably tastes better but are you sure you want to eat it?
The path of least resistance can be a slippery slope. Take care that fixing your fixes of fixes doesn't snowball and end up costing you more than fixing the root cause would have in the first place.
