Difference between Supply Performance and Vendor delivery performance on receipt

Can someone explain to me the difference between these two reports and their intended uses?

These are found under Procurement and Sourcing > Reports > Distribution


I get conflicting information for "On-Time" and "Average Days Late" between the two reports.


In order to find out more  I created test-data with delayed PO's, but they are not shown on the Supply Performance report.

The Vendor delivery performance on receipt seems to make more sense to me.
