Hi Manu,
I am not sure what you want.
Do you mean by "reports" like SE38 reports with which you can do reporting like "how many inbound deliveries exists for date x with status y from vendor z?"
For reporting EWM usually does not use reports but there the EWM monitor exists which is a central place from where you can do all kinds of "reporting" / selections for example for objects like:
- inbound deliveries
- outbound deliveries
-...
But I think that without a system it will be hard for you to get an impression on this.
Maybe search the SCN for terms like "EWM monitor". Then you will find for example some blogs like:
