Sasidhar,
That's easy. No, there is no way, because SAP MTS confirmations do not confirm based upon stock or ASN or PO. They confirm based upon the calculated ATP quantity at the time the confirmation was created. Calculated ATP quantity in turn is based upon ALL configured supply elements and ALL configured demand elements, using SAP's ATP algorithms.
In your example above, in addition to what you have displayed, you would need to know the dates of all objects, and you would need to know the dates that each of the ATP checks were executed. From this data you could INFER which objects were used for which confirmations.
I hear this question often. The simple answer is that there is no 'pegging' (linkage between supply and demand elements) during SAP's ATP.
If you know the exact situation prior to ATP check, you can accurately predict what will be the outcome. However, once the confirmation is created, there is no way via the confirmation itself to determine what the ATP situation was at the time of the check.
