The SAP P2P process connects purchasing, goods receipt, supplier invoicing and payment. It shows how Materials Management activities interact with Financial Accounting. For a beginner, the most useful goal is to trace each business event to its documents and accounting impact.
The example below is an original learning exercise for a standard valuated stock purchase. It excludes taxes, freight, discounts and price differences. Actual entries depend on valuation, configuration and the business scenario; confirm the product edition and training environment before following system steps.
A simple purchasing scenario
A fictional company buys 10 identical items for ₹1,000 each. All items arrive together and the supplier invoices the agreed ₹10,000. The company later pays the invoice in full. Write down the expected quantity, value and remaining liability before checking the system result.
SAP P2P process and illustrative entries
| Event | Business purpose | Simplified accounting |
|---|---|---|
| Purchase order | Record agreed purchase | Normally no FI posting for this standard example |
| Goods receipt | Record stock received | Debit inventory ₹10,000; credit GR/IR ₹10,000 |
| Supplier invoice | Record amount owed | Debit GR/IR ₹10,000; credit supplier ₹10,000 |
| Payment | Settle supplier liability | Debit supplier ₹10,000; credit bank or bank-clearing account ₹10,000 |
Payment processing can involve intermediate bank-clearing postings. The table simplifies the settlement for teaching purposes.
What GR/IR helps you investigate
GR/IR means goods receipt/invoice receipt. In this matched example, the receipt and invoice offset each other. A balance is a reason to investigate timing, missing documents or differences; it does not automatically prove an error. SAP’s procure-to-pay lesson explains the standard process and document relationships.
Build a useful practice record
- Record the fictional purchase requirement and assumptions.
- Predict the inventory quantity and value after receipt.
- Identify the related purchasing, material and accounting documents.
- Compare invoice quantity and value with the order and receipt.
- Check the supplier open item before payment and clearing afterward.
- Explain any difference between your prediction and the observed result.
Use a table with columns for test case, input, expected result, actual result and evidence. Keep only approved training data. Do not describe a classroom exercise as client implementation work.
Try two variations
First, assume only six items arrive. What quantity should remain open, and what evidence would you check before entering an invoice? Second, assume the invoice has not arrived at month end. What documents would explain the remaining GR/IR balance? Treat these as investigation questions rather than instructions to post an adjustment.
Common questions
Does every purchase order create an accounting entry?
In the standard stock example above, the purchase order does not create an FI posting. Other accounting commitments and scenarios require separate consideration.
Is MM knowledge useful for FICO learners?
Yes. Understanding the purchasing event helps you explain why finance entries occur and what evidence supports them.
