Materials Management (MM) and Sales & Distribution (SD) are where goods and money move. Each step creates a document, and the documents link together.

Procure-to-pay (MM)

1. Purchase requisition (ME51N): someone needs something.
2. Purchase order (ME21N): sent to the vendor.
3. Goods receipt (MIGO): stock in; creates material and accounting documents.
4. Invoice verification (MIRO): 3-way match PO / GR / invoice.
5. Payment (F110 payment run): clears the vendor invoice.

Order-to-cash (SD)

1. Sales order (VA01): pricing, availability, credit check.
2. Delivery (VL01N): picking, packing, goods issue (stock out).
3. Billing (VF01): the invoice; posts to FI receivables.
4. Payment: incoming payment clears the customer invoice.

Document flow

From any document, Environment › Display document flow shows the whole chain with statuses. It’s the first place to look when someone asks “was this invoiced?”
