• What is the cause and solution for SAP error message AU138 - Account &2 is not a reconciliation account ?

  The SAP error message AU138 indicates that the account specified (denoted as &2 in the message) is not a reconciliation account. This typically occurs in the context of financial transactions where a reconciliation account is expected, such as in the integration between the General Ledger (G/L) and sub-ledgers (like Accounts Receivable or Accounts Payable).
  Cause:
  
  Account Type: The account you are trying to use is not set up as a reconciliation account in the system. Reconciliation accounts are specific G/L accounts that are linked to sub-ledger accounts.
  Configuration Issues: The account may not have been properly configured in the system to serve as a reconciliation account.
  Transaction Type: The transaction you are attempting to execute may require a reconciliation account, but the account you are using does not meet this requirement.
  
  Solution:
  
  
  Check Account Configuration:
  
  Go to the account master data in SAP (transaction code FS00).
  Verify that the account in question is set up as a reconciliation account. This can be checked in the account's settings under the "Control Data" tab.
  Ensure that the account type is appropriate for the reconciliation account (e.g., it should be a G/L account linked to a sub-ledger).
  
  
  
  Change Account Type:
  
  If the account is not a reconciliation account and needs to be, you may need to change its configuration. This typically involves:
  
  Creating a new G/L account as a reconciliation account.
  Assigning the new account to the appropriate sub-ledger (e.g., customer or vendor).
  
  
  
  
  
  Review Transaction:
  
  Ensure that the transaction you are trying to execute is appropriate for the account type you are using. If it requires a reconciliation account, you will need to use the correct account.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or consult with your SAP administrator for specific configuration steps and best practices related to reconciliation accounts.
  
  
  
  Related Information:
  
  Reconciliation Accounts: These are special G/L accounts that aggregate the balances of sub-ledger accounts. For example, in Accounts Receivable, the reconciliation account will summarize all customer transactions.
  Sub-ledger Integration: Understanding how sub-ledgers (like AR and AP) integrate with the G/L is crucial for proper financial reporting and transaction processing.
  SAP Transactions: Familiarize yourself with relevant SAP transactions such as FS00 (G/L Account Master Record), FBL1N (Vendor Line Item Display), and FBL5N (Customer Line Item Display) for managing accounts.
  
  If you continue to face issues after checking the above points, it may be beneficial to involve your SAP support team or a consultant who specializes in SAP Financials.
