📚 Example Use Case in a University
A professor submits a purchase requisition (ME51N) for lab chemicals. The purchasing team reviews and converts it into a purchase order (ME21N). When the chemicals arrive, the store department does a goods receipt (MIGO). The invoice from the vendor is verified and paid through MIRO. Inventory is updated automatically, and the chemicals are ready for use.
