SAP Table EKKO

A purchasing document has a header and one or more line items. The header is stored in table EKKO the line items are stored in table EKPO. The two tables can be linked together based on the purchasing document number (field EBELN). The header contains information relevant to the whole document. The items specify the materials or services to be procured. For example, information about the vendor and the document number is contained in the document header, and the material description and the order quantity are specified in each item.

The purchasing document table contains different categories of documents that share the same document structure but do not necessarily have the same business purpose. The document category is defined in field EKKO.BSTYP. The following document categories can be found in tables EKKO/EKPO:

Request for quotation (RFQ)

Transmits a requirement defined in a requisition for a material or service to potential vendors. The purpose is to ask vendors to send in quotations.

Quotation

Contains the prices and conditions received from the vendor and is the basis for vendor selection.

Purchase order (PO)

Contract

Scheduling agreement
