SQVI Report Question

Hi,

I'm trying to write a report using tcode SQVI. The report would include Customer, sales order, delivery and Invoice.

For which I'm using KAN1 -- VBAK -- VBAP -- LIPS -- VBRP -- VBRK. All the joins work well and I'm getting the desired result but how do I get results of sales order which haven't been delivered and invoice yet?

At the moment I'm getting results for sales orders which have been completed but not open sales order.

regards,

Hamid
