Sooraj,
How can we understand why was the SO confirmed (against which stocks or IBD maybe?) and why isn't the Delivery picking any existing stocks?
Review CO09 using Business Event A. This is the rule used by Sales documents.
If you see the CO09 for B below, at stock level out of 4.200, 2.016 is available, why isn't this 2.016 being used to create the Delivery which we are facing problem?
That 2016 availability that you have indicated is only for storage location 1000. Your sales order is not relevant for storage location 1000.
Best Regards,
