¿Por qué enseñar P2P end-to-end?

Porque compras, almacén y finanzas dependen entre sí y las excepciones tienen causas aguas arriba.

¿Todo P2P impacta ACDOCA?

El impacto financiero aparece en movimientos valorados, facturas y pagos.

Procure-to-Pay SAP S/4HANA training

Ciclo completo de compras MM desde solicitud hasta pago al proveedor.

Resumen del proceso y contexto de negocio

Procure-to-Pay conecta compra operativa, recepción, verificación de factura y pago. En S/4HANA se debe ver toda la cadena porque un pedido débil, una recepción tardía o una factura bloqueada afecta a finanzas y al proveedor.

Los alumnos explican cómo una necesidad de compra se convierte en una obligación contabilizada y pagada.

Gu?a paso a paso

Create the purchase requisition

Capture material, plant, quantity, delivery date, account assignment, and requester.

Atenci?n: If account assignment is wrong, invoice verification may block later even though purchasing looked correct.

Convert or create the purchase order

Confirm supplier, price, tax code, purchasing organization, delivery tolerances, and approval status.

Atenci?n: Avoid teaching ME21N as typing practice; explain why each field controls downstream receipt and invoice behavior.

Post goods receipt

Receive against the PO and check stock, valuation, and GR/IR postings.

Atenci?n: A late or missing goods receipt is one of the most common causes of blocked invoices.

Verify supplier invoice

Run the three-way match between PO, receipt, and invoice, then analyze any block.

Atenci?n: Price, quantity, and tax differences should be classified before they are released.

Pay and clear supplier item

Execute payment proposal, review exceptions, post payment, and confirm clearing.

Atenci?n: Payment terms and baseline date are master-data topics, not only finance topics.

Errores comunes y soluci?n

Invoice blocked for quantity variance

Causa probable: Supplier invoiced more than received or receipt was not posted.

Ruta de soluci?n: Check MIGO/MATDOC receipt and tolerance settings before releasing the block.

Wrong account assignment

Causa probable: Cost center, asset, WBS, or GL account was missing or incorrect on PR/PO.

Ruta de soluci?n: Correct the purchasing document if possible; otherwise document the finance correction path.

GR/IR balance remains open

Causa probable: Receipt and invoice quantities or values do not reconcile.

Ruta de soluci?n: Analyze PO history, invoice documents, and clearing logic before month-end close.
