How to check if outline agreement of material same as agreement of PO?

Hi Experts,

Thank you for taking the time to read my question.

I would just like to know, with regards to SAP tables, how can I check whether the outline agreement on a purchase order item matches the outline agreement of a material? In other words to check if an item was purchased out of contract. I know you can check EKPO/EKKO for the KONNR field, but how do I know that this is the correct Outline Agreement for the specified material?

Any advice would be appreciated.

Best Regards,

Frans
