rebate income or provisions for accrued rebate income from
<DS:GLOS.3526C095AFAB52B9E10000009B38F974>subsequent settlement</> are
posted (postings of provisions for accrued income are not subject to
tax).
Therefore, the indicator "Posting without tax allowed" must be set for

However, this is not the case.

• What is the cause and solution for SAP error message MN456 - G/L account & in company code & does not allow posting w/o tax code ?

  The SAP error message MN456 indicates that a General Ledger (G/L) account in a specific company code does not allow postings without a tax code. This typically occurs when you attempt to post a transaction that requires a tax code, but the system is configured to enforce tax code requirements for that particular G/L account.
  Cause:
  
  G/L Account Configuration: The G/L account in question is set up in such a way that it mandates a tax code for postings. This is often the case for accounts that are related to sales, purchases, or any transactions that are subject to taxation.
  Company Code Settings: The company code settings may also enforce tax code requirements for certain types of transactions.
  Transaction Type: The type of transaction you are trying to post may inherently require a tax code (e.g., sales invoices, purchase invoices).
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check G/L Account Settings:
  
  Go to the G/L account master data (transaction code FS00).
  Verify the settings for the G/L account in question. Check the "Tax" tab to see if the account is set to require a tax code.
  If necessary, adjust the settings to allow postings without a tax code, but be cautious as this may have implications for tax reporting.
  
  
  
  Provide a Tax Code:
  
  When posting the transaction, ensure that you include a valid tax code that corresponds to the nature of the transaction. This is often the simplest solution if the account is meant to require a tax code.
  
  
  
  Review Company Code Configuration:
  
  Check the company code settings related to tax configuration (transaction code OBY6).
  Ensure that the tax settings align with your business requirements and that they are correctly configured.
  
  
  
  Consult with Finance Team:
  
  If you are unsure about changing G/L account settings or tax configurations, consult with your finance or accounting team to ensure compliance with tax regulations.
  
  
  
  Transaction Type Review:
  
  If the transaction type you are using does not require a tax code, consider using a different transaction type that aligns with your posting requirements.
  
  
  
  Related Information:
