My team is struggling to turn approved consulting service POs into proper Service Entry Sheets (SES) and the corresponding invoices inside the SAP Ariba Invoicing module. I am looking to streamline this process and eliminate repeated rework and rejections coming back from our finance group. What I need • A clear, recorded walkthrough of the exact clicks and fields required to open, complete, and submit an SES for consulting services. • Confirmation that each SES correctly pulls the service lines, rates, and tax codes already held in the PO. • Guidance on turning the approved SES into a compliant invoice, including tips for handling partial invoicing or multiple billing periods. • A concise cheat-sheet or SOP we can reuse for future entries. Access can be provided to our test tenant first, then production once the workflow is proven. Screen-sharing sessions are fine; written guidance must be included as a final deliverable so the process is repeatable without external help. Acceptance criteria • At least one live SES and one invoice submitted without error in production. • Documentation delivered as a PDF or Word file outlining each step, plus screenshots. • All terminology and field names match exactly what appears in SAP Ariba Invoicing. If you are comfortable navigating SAP Ariba Invoicing and have already completed similar work for consulting or professional-services POs, you will be able to wrap this up quickly.
