AX 2009 / 2012 CS database collation

Question

I've found several articles, posts and threads that case sensitive database collation isn't supported. Neither by 2009 nor by 2012. In Installation-progress, you'll be faced with this, latest. But I wasn't able to find a concrete reason for that behaviour.

So - what's the reason, CS collation isn't allowed?

Answer 1

String comparisons are case insensitive in X++. Using a case sensitive database on a case insensitive programming environment would be strange indeed.

Example: transactions may be created with currencies "usd" or "USD". Different currencies?
