How to group billing documents into a single invoice?

[Former Member]

Hi, I am trying creating single invoice against group of few billing documents. But as per our business scenario this single invoice will not be accounted.

Example- I have a two single invoices (A & B)

A with 3items (X, Y & Z) & B with 2 items (S&M)

Now we need to create a group invoice C with make join all items(X, Y, Z, S &M) and summed their total prices & quantity.

I already configured the copy control and its create a new invoices copying data from the original once. . It does not group the invoice.

Please suggest.
