PO Vendor Contacts -- CORP and PRIME - What is a contact level and where can I change these different vendor contact records?

Hi and thanks for your help,

When I drill on the PO10.1 Vendor, I see that under the Vendor Contacts Folder there are two different entries in our system. One is named CORP and the other is named PRIME. These are listed as Contact Level 1 and Contact Level 0 respectively.

When I change information in PO10.1 it only changes the information in the PRIME or Contact Level 0 record.

Is there a Lawson screen that allows me to see and change the CORP or Contact Level 1 information?

Thanks again for your help,
