Managing services accurately is just as important as managing materials, especially when it comes to invoicing, compliance, and financial control. In SAP, Service Entry Sheets (SES) are used to confirm that a service has been performed before a supplier invoice is posted. Whether you’re correcting an entry or creating a new one, knowing the right steps (and limitations) can save time and prevent downstream issues.
This guide walks you through how to add and edit Service Entry Sheets in SAP, including best practices to avoid common pitfalls.
A Service Entry Sheet is a document used to record and approve services rendered against a Purchase Order (PO). Once approved, the SES enables invoice verification and payment.

Fix: Always add meaningful long text

Best practices for Service Entry Sheets in SAP include always referencing the correct purchase order to ensure services are matched accurately, entering services as soon as the work is completed to prevent delays or discrepancies, and using clear, detailed descriptions to support audit and compliance requirements. It’s also important to double-check quantities and pricing before submission to avoid invoice blocks or rework, and to avoid making last-minute changes after approval, as approved Service Entry Sheets are typically locked and can be difficult to correct.
Service Entry Sheets play a critical role in ensuring accurate service confirmation, timely invoicing, and strong financial control within SAP. By understanding how to properly create and edit Service Entry Sheets and by following best practices to avoid common errors, organizations can reduce approval delays, minimize invoice discrepancies, and maintain clean, auditable procurement processes. A disciplined approach to service entry not only improves operational efficiency but also strengthens trust between procurement, finance, and suppliers.
