How to identify the Open Schedule Lines.

Question

Hi All,
I am writing an ABAP report which requires to identify the OPEN SALES ORDER SCHEDULE LINES.
The requirement is to identify the Open Sales Order Schedule Lines for a particular month (user Processing month in the selection screen).  Here the Schedules line item could have been delivered already.  If it is not Billed then it is OPEN schedule line.
Can anyone help me to understand the logic which I need to apply to identify only the Open sales order scshedule lines.
I am using the following tables:
VBAK,VBAP,VBUK,VBUP,VBEP.  Is there any other table which I need to use?  I am trying to avoid using table VBFA due to performance issues.
Thanks in Advance
Regards

Hi Gopal,
If you want to find status of any sales order line item then you can find from following method from VBUP table.
In VBUP table there is a field FKSTK.By this filed status we can find billing status of particular sale order and this field has four possible values and these are
<i><b>field value  field value meaning</b></i>                             
if this value is space then order is not Not Relevant for billing             
if this value is  'A'  then order is    Not yet processed
if this value is   'B' then order is Partially processed
  if this value is  'C' then order   Completely processed
If you want to find status for the header then go to VBUK table and process is same as above.
In these table we can find all types of status.
