Missing Purchasing docs between EKPO and PSA

Hi everyone,

We are implementing the purchasing solution for the first time at the client. When testing the data, we noticed that certain PO's that are in the tables EKPO are not showing up in the 2lis_02_ITM PSA. I think even RSA3 doesn't show those records. Can someone please help me understand why that would happen? We have no special logic and these are standard extractors.

There are many PO ranges that seem to have missing PO's, such as 4500 series, 6000, 7000 and 8000 series.

Appreciate all your help and points will be awarded.
