For operating expenses and supplies, purchase requisitions (PRs) entered into SAP were printed and the approval process (requisitioner, budget manager and management control) was paper-based, causing a certain amount of inertia in the process, especially when the signatories were not “on site”. The process was working well overall, but there was a need for greater efficiency: time savings, improved quality and traceability in SAP. The purchasing department therefore decided to switch to a paperless validation, approval and information circuit for purchase orders.
