Consolidated entries in Invoice Accounting Doc

Question

Hi gurus!
Please throw some light.
If my invoice is carrying 100 line items, how am I able to consolidate my accounting doc’s entries in 1 G/L account such that instead of having....
                DR          Accts Receivable              $1000
                CR           Sales                              $20
                CR           Sales                              $25        
                CR           Sales                              $15
                CR           Sales                              $40
.... I wanted to make it
                DR          Accounts Receivable      $1000
                Cr            Sales                           $1000

Thanks for your answers. But im only referring to one invoice.
My invoice will have several line items and once it generates an accounting document it will post SALES entries for each material line item.
Ex. Here what's happening:
Invoice 1000001 customer JOhn Smith
          material 1      $100
          material 2      $150
          material 3      $100
Acctg Doc 10000001
          Debit John Smith  $ 350
          Credit Sales $100
          Credit Sales $150
          Credit Sales $100
How possble to make it summarized:
          Debit John Smith  $ 350
          Credit Sales $350
Thank you guys for responding. I really appreciate it.
