R12 AR > create accounting > view output is not listing all the invoices

HI ,

My scenario is

1. R12 > AR .  I created around 20 invoices almost with same data but change in tax rates

2. Run the create accounting till present date > Draft mode

3. Run the create accounting till present date > in Final mode

4. when i see the view output > some invoices are not listed

some invoices are still in Draft mode

Some invoices are in final mode but not listed in view output

Any idea why such thing happens and what is the action needs to be taken
