Change In Schedule date

Greetings..........

i have one BOM ..which contain Finish , semifinsih and raw material in BOM.

Now i have created the Demand for finish Product and taken MRP Run in MD02.

Now as per Routing data system has gievn me the Basic start & Basic finish date for planned order of Finish & Semifinish . Now after converting Palnned order to produciton order i get the Schedule start & shedule finish date of each prodcuiton order.

Now this is therotical date calcualted by SAP, but in practical case if this is not achive , means suppose there is malfunctionin shop and actaul date is not achived for semifinsh.

So is there any report where i can see the expected and change in date of finish product production schedule finsih date.
