VA32 Cumm Qty in Transit and Open Qty

Hi,

Can any pls help me in understanding why on a Sales Scheduling Agreement,

if there is a Qty in transit (from previous delivery and customer still did not receive / send the updated EDI), then why is it consuming the open qty of future delivery schedules??

The Qty in transit is for deliveries done on 7/9 and 7/14. will take 1-2 wks for the customer to receive n send the updated EDI.

And we still need to delivery on 8/3 and 8/10 a qty of 2000 pcs each.

But the Open Qty is 0. So not able to deliver it. Also not visible in MD04.

So how can I deliver the 8/3 qty?

Thanks,

Raj
