What is SES in SAP System?

SES in SAP stands for "Service Entry Sheet," which is a document used in the SAP system to record the details of services rendered by a vendor. It serves as a formal acknowledgment that the services have been provided and is typically used in conjunction with the Purchasing module. The SES allows for the verification of services against the purchase order and is essential for processing invoices and making payments. It helps streamline the procurement process and ensures accurate record-keeping.
