Unable to display and update Vendor

Hi Experts,

I am Unable to display and update particular Vendor .

Error : The connection to the server was reset

I was going through below queries and data looks good in all tables.

select * from AP_SUPPLIERS where segment1 = 'E97166';

select * from AP_SUPPLIER_SITES_ALL where vendor_Id in (select vendor_id from ap_suppliers where segment1 = 'E97166');

select * from HZ_PARTIES where party_id in (select party_id from ap_suppliers where segment1 = 'E97166');

select * from HZ_PARTY_SITES where party_site_id in (select party_site_id from ap_supplier_sites where vendor_Id in (select vendor_id from ap_suppliers where segment1 = 'E97166'));
