How to find out how may deliveries are created for a schedule line?

Hi

In our project user wants a report which shows how may deliveries are created for a schedule line. As you know schedule line mumber is dynamic and it keeps changing for each line item becaues of availibility check in VBEP.

Do you people know any standared or development way to find out how many deliveries are created for a schedule line

Thanks in advance for you kind help
