Number range for Sales document,Billing Document and Delivery Document

Hi,

Please advise how to know which document is assigned with what number range.

For example :

I used Table TVAK to get data for sales document.Through this i got the list of sales document and also i could take print out.

But i does not know from which table i will get similar kind of data for delivery document and billing document types.

Because i need to decide which number range to set.

Thanks,
