Dear Ravi
I would like to add some more findings here.
Open Delivery: means Delivery done--need to go for billing.
Is it what you are asking for??
(confirm--there is always difference between client terminology and SAP terminology)
If so-- First you retrieve all delivery docs from LIPS table--then retrieve the status of Billing from VBUP table(FKSTA)...
So you can easily find the open delivery Qty(again reiterating Open delivery Qty means-the Qty for which delivery happened--but not billed)
Note: I want to add a little bit to Experts opinion here---if a material is having availability check of KP--will not be observed in VBBE.
Please find the answer Given By Our Lakshmipathi sir in thread--VBBE table Not Updated....
Hope this helps.
