• What is the cause and solution for SAP error message FINS_ACDOC_CUST309 - Ledger group &1 requires a mapping assignment to ledger &2 ?

  The SAP error message FINS_ACDOC_CUST309 indicates that there is a missing mapping assignment between a ledger group and a specific ledger in the system. This typically occurs in the context of Financial Accounting (FI) and Controlling (CO) when working with the Universal Journal (ACDOCA) in SAP S/4HANA.
  Cause:
  The error arises when:
  
  A ledger group is configured in the system, but there is no corresponding mapping to the actual ledger.
  The system requires a mapping to determine how to post transactions to the correct ledger based on the ledger group specified.
  
  Solution:
  To resolve this error, you need to create or update the mapping assignment between the ledger group and the ledger. Here are the steps to do this:
  
  
  Access the Customizing Transaction:
  
  Go to transaction code SPRO (SAP Project Reference Object).
  Navigate to Financial Accounting (New) > General Ledger Accounting (New) > Master Data > Ledger > Define Ledger Group.
  
  
  
  Define Mapping:
  
  In the configuration, look for the option to define the mapping for ledger groups.
  Ensure that the ledger group specified in the error message has a corresponding mapping to the ledger mentioned in the error.
  
  
  
  Create or Update Mapping:
  
  If the mapping does not exist, create a new entry that links the ledger group to the appropriate ledger.
  If the mapping exists but is incorrect, update it to ensure it points to the correct ledger.
  
  
  
  Save Changes:
  
  After making the necessary changes, save your configuration.
  
  
  
  Test the Configuration:
  
  After saving, perform a test transaction that previously triggered the error to ensure that the issue is resolved.
