VENDOR_ID : Yes Supplier unique identifier
SEGMENT1 : Supplier number
AP_SUPPLIERS stores information about your supplier level attributes. Each row includes the purchasing, receiving, invoice, tax, classification, and general information. Oracle Purchasing uses this information to determine active suppliers.
This table replaces the old PO_VENDORS table. The supplier name, legal identifiers of the supplier will be stored in TCA and a reference to the party created in TCA will be stored in AP_SUPPLIERS.PARTY_ID, to link the party record in TCA.
