• What is the cause and solution for SAP error message WS885 - Enter the posting key for special general ledger indicator & ?

  SAP Error Message:
  
  WS885 - Enter the posting key for special general ledger indicator &
  
  Cause:
  This error occurs during document posting in Financial Accounting (FI) when you are trying to post a transaction involving a Special G/L indicator (such as down payments, guarantees, bills of exchange, etc.), but the system does not find a valid posting key assigned to that special G/L indicator for the relevant account type.
  In other words, the system expects a posting key to be defined for the special G/L indicator you are using, but it is missing or not maintained in the configuration.
  
  Explanation:
  
  Special G/L transactions are used to handle special business transactions like down payments, bills of exchange, guarantees, etc.
  Each special G/L indicator must be linked to a posting key that controls the type of posting (debit/credit, field status, etc.).
  If the posting key is not maintained for the special G/L indicator and account type combination, SAP cannot determine how to post the line item, hence the error.
  
  
  Solution:
  
  
  Check the Special G/L Indicator and Posting Key Configuration:
  
  
  Go to transaction code OBYR (or navigate via IMG):
  SPRO -> Financial Accounting -> Accounts Receivable and Accounts Payable -> Special G/L Transactions -> Define Posting Keys for Special G/L Transactions
  
  
  Here, you will find the assignment of posting keys to special G/L indicators for different account types (Customer, Vendor, G/L accounts).
  
  
  
  
  Maintain the Posting Key:
  
  Identify the special G/L indicator causing the error (the message will show it as &).
  Assign the correct posting key for the relevant account type.
  Save the configuration.
  
  
  
  Verify Posting Key Settings:
  
  Ensure the posting key assigned allows the correct debit/credit posting.
  Check field status and other controls if necessary.
  
  
  
  Test the Posting Again:
  
  After maintaining the posting key, try posting the document again.
  The error should no longer appear.
  
  
  
  
  Additional Information:
  
  Special G/L indicators are used to differentiate special transactions from normal postings.
  Common special G/L indicators include:
  
  A for down payments
  B for bills of exchange
  K for guarantees
  
  
  Posting keys control the line item behavior, such as whether the line is debit or credit, whether the amount is entered, and field status.
