📄 Understanding Document Posting in SAP: A Beginner's Guide

📌 Introduction

In SAP, document posting is a core financial function. It refers to the process of recording financial transactions in the system—whether it's an invoice, payment, or adjustment. As someone who recently completed my SAP FICO course from Unite Academy, I'm excited to share how this process works and why it's important in the world of finance and accounting.

💡 What is Document Posting in SAP?

Document posting involves entering a financial transaction into the SAP system. Each posted document updates the company's financial statements in real time. These documents include:

• Vendor Invoices

• Customer Payments

• Journal Entries

• Bank Transactions

Every document contains debits and credits, respecting the double-entry bookkeeping principle.

🔧 Steps to Post a Document in SAP

Let’s look at the standard process of posting a document using FB50, a common transaction code in SAP for general ledger postings:

1️⃣ Log in to SAP and Enter T-code FB50

This transaction is used for GL account postings (General Ledger).

2️⃣ Fill in Header Details

• Document Date: The date of the transaction.

• Posting Date: The date when it will reflect in accounts.

• Document Type: Like SA (GL Posting), KR (Vendor Invoice), etc.

• Reference: Any invoice number or internal reference.

3️⃣ Enter Line Items

• Debit or Credit the appropriate GL accounts.

• Enter Amounts, Cost Center (if required), and Business Area.

4️⃣ Simulate the Entry

Use the Simulate button to check for errors before posting.

5️⃣ Post the Document

Click Post. The system generates a unique Document Number.

✅ Real-World Example

Let’s say your company pays rent of ₹50,000. You would:

• Debit: Rent Expense Account ₹50,000

• Credit: Bank Account ₹50,000

• Post this using FB50 or F-02

This ensures your P&L account and bank ledger are both updated.
