How to customize oxbillnr

Hey people,

looking for a solution, on how to customize the oxbillnr.
I don’t want it to be only numerical, it needs to have alphanumerical chars as well.
Is there a way to customize the pattern of it?
In length and allowed chars?
Or is it better to have a own field for that case?

// nevermind, got it.
Thank you

So you “got it” (already done) or not yet?

Whatever, I have customized the numbering style to random # and it can also be combined with the Standard Counter. Whatever you like is possible.
