Differences between FB01 and FBB1

Updated Sep 12, 2023

Within SAP's Financial Accounting module, two important transaction codes, FB01 and FBB1, serve distinct purposes. This article will explain what each of these T-codes is and highlight the key differences between them.

What is T-code FB01?

T-code FB01 is a transaction code in SAP that stands for Post Document. The t-code FB01 is used to post regular financial accounting documents within the SAP system. These documents typically involve recording various financial transactions, such as invoices, payments, or journal entries.

What is T-code FBB1?

T-code FBB1 serves a different purpose in SAP. It is used for "Post Foreign Currency Valuation" and is part of the FIGL (Financial General Ledger) package. This t-code is specifically designed for foreign currency valuation entries. Its primary function is to calculate and post valuation adjustments for assets and liabilities denominated in foreign currencies to account for exchange rate fluctuations.


Key Differences between FB01 and FBB1

  • T-code FB01 deals with regular financial accounting transactions, such as invoices and journal entries, whereas T-code FBB1 is exclusively used for foreign currency valuation entries, which involve assessing and adjusting the values of assets and liabilities denominated in foreign currencies.
  • T-code FB01 can be used to post financial documents at any time, as needed, whereas T-code FBB1 is typically used for month-end foreign currency valuations to ensure that financial statements accurately reflect the impact of exchange rate fluctuations.
  • T-code FB01 is available for use by the general finance user community to handle routine financial transactions, whereas T-code FBB1 is often restricted to users in the corporate finance department, specifically for month-end foreign currency valuation purposes. 
  • T-code FB01 allows the posting of transactions to various accounts, including clearing accounts, whereas T-code FBB1 is primarily concerned with accounts related to foreign currency assets and liabilities. It is used to post adjustments that account for exchange rate changes.
