  The SAP error message RW661 indicates a mismatch between the ledger group specified in a transaction and the target ledger group that the system expects. This typically occurs in the context of financial postings or when working with multiple ledgers in SAP S/4HANA or SAP ERP systems.
  Cause:
  The error arises when:
  
  Inconsistent Ledger Group Assignment: The ledger group assigned to the document or transaction does not match the ledger group defined in the target settings (e.g., in the configuration of the financial document).
  Configuration Issues: There may be a configuration issue in the financial accounting settings, particularly in the ledger settings or in the document type settings.
  Posting to Incorrect Ledger: The user may be attempting to post to a ledger that is not allowed for the specific transaction type or document type.
  
  Solution:
  To resolve the RW661 error, you can take the following steps:
  
  
  Check Ledger Group Assignment:
  
  Verify the ledger group assigned to the transaction. Ensure that it matches the expected target ledger group.

  Financial Accounting (FI) > General Ledger Accounting > Ledger > Define Ledger Groups.
  
  
  Ensure that the ledger groups are correctly defined and that the necessary settings are in place.
