• What is the cause and solution for SAP error message KD321 - Settlement of parallel ledgers requires unique currency types ?

  The SAP error message KD321, which states "Settlement of parallel ledgers requires unique currency types," typically occurs in the context of controlling (CO) when you are trying to settle costs or revenues across different ledgers that have conflicting currency settings. This error is related to the configuration of parallel ledgers in SAP, particularly when dealing with multiple currencies.
  Cause:
  
  
  Parallel Ledger Configuration: The error arises when you have multiple parallel ledgers configured in your SAP system, and these ledgers are set up with different currency types. For example, one ledger might be using a local currency while another uses a group currency or a different foreign currency.
  
  
  Settlement Process: During the settlement process, SAP requires that the currency types for the ledgers involved in the settlement be unique. If they are not, the system cannot determine how to handle the currency conversion or allocation.
  
  
  Master Data Issues: There may be inconsistencies in the master data settings for cost centers, internal orders, or other controlling objects that are being settled.
  
  
  Solution:
  
  
  Check Ledger Configuration: Review the configuration of your parallel ledgers in the SAP system. Ensure that each ledger has a unique currency type assigned. You can do this by navigating to the configuration settings for Financial Accounting (FI) and Controlling (CO).
  
  
  Review Cost Objects: Check the cost objects (like cost centers, internal orders, etc.) involved in the settlement. Ensure that they are assigned to the correct ledgers and that their currency settings are consistent.
  
  
  Adjust Currency Settings: If necessary, adjust the currency settings for the ledgers or the cost objects to ensure that they align correctly. This may involve changing the currency type in the master data or reconfiguring the ledgers.
  
  
  Consult Documentation: Refer to SAP documentation or notes related to parallel ledgers and currency settings for more detailed guidance on how to configure these settings correctly.
  
  
  Testing: After making changes, perform a test settlement to ensure that the error does not reoccur.
  
  
  Related Information:
  
  Transaction Codes: You may need to use transaction codes like OB22 (for defining currency types) or OKB9 (for configuring parallel ledgers) to access the relevant settings.
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional troubleshooting steps.
  User Roles: Ensure that you have the necessary authorizations to make changes to ledger configurations and master data.
  
  If the issue persists after following these steps, it may be beneficial to consult with your SAP support team or a consultant who specializes in SAP CO module configurations.
