Hi Sagar,

You can go to transaction SQVI and here create table join for tables VBRK & VBRP.

Select the relevant fields as your input and list fields.

Give the input field as billing date range.

So for eg, now if you enter say 01.01.2008 - 31.01.2008, you can see all the billing documents created between these two dates irrespective of whoever your customer is.

Hope this helps.

Reward points if helpful.

Regards

Ravi
