SAP Supplier Master Data Underlying Tables
In the context of SAP systems, supplier master data is stored across multiple tables designed to hold different aspects of information related to suppliers. The primary table used for storing general supplier details is LFA1. This table contains basic identification and classification attributes such as company code, purchasing organization, and vendor number.
Additional important tables include:

LFAD: Holds address-related information about suppliers.
LKPF: Contains conditions and terms agreed upon with suppliers.
****EBAN***: Manages purchase requisitions linked to specific vendors.
EKPO: Stores detailed line items from purchase orders associated with each supplier[^1].

For comprehensive management within an SAP environment transitioning or operating under configurations like those mentioned in discussions on evolving landscapes including retail settings, understanding how these tables interrelate becomes crucial when performing operations involving supplier master data maintenance or conversion processes.
To query this data directly through SQL-like commands within ABAP would look something similar to below example which retrieves some key fields from several relevant tables:
SELECT lfa1.lifnr AS VendorNumber,
lfad.stras AS StreetName,
lkpf.knumv AS ConditionRecord,
eb.anln1 AS RequisitionLongText,
ekpo.ebeln AS PurchaseOrderDocumentNumberOfPurchasing
FROM lfa1
JOIN lfad ON lfa1.lifnr = lfad.lifnr
LEFT JOIN lkpf ON lfa1.lifnr = lkpf.lifnr
LEFT JOIN EBAN eb ON lfa1.lifnr = eb.lifnr
LEFT JOIN ekpo ON lfa1.lifnr = ekpo.lifnr;
