• What is the cause and solution for SAP error message AC111 - Target and source transaction types cannot be identical ?

  The SAP error message AC111, which states "Target and source transaction types cannot be identical," typically occurs in the context of asset accounting when you are trying to perform a transaction that involves transferring or posting assets. This error indicates that the system has detected that the source and target transaction types you are trying to use are the same, which is not allowed.
  Cause:
  The primary cause of this error is that the transaction types specified for the source and target are identical. In asset accounting, different transaction types are used to differentiate between various types of transactions (e.g., acquisition, transfer, retirement). The system requires that the source and target transaction types be different to ensure proper accounting treatment and to maintain the integrity of asset records.
  Solution:
  To resolve this error, you should:
  
  
  Check Transaction Types: Review the transaction types you are using for both the source and target. Ensure that they are not the same. For example, if you are trying to transfer an asset, the source transaction type might be "Acquisition" and the target should be a different type, such as "Transfer."
  
  
  Modify the Transaction: If you find that you have mistakenly selected the same transaction type for both source and target, change one of them to a different, appropriate transaction type.
  
  
  Consult Documentation: Refer to SAP documentation or your organization's asset accounting guidelines to understand the correct transaction types to use for your specific scenario.
  
  
  Test the Changes: After making the necessary adjustments, try to execute the transaction again to see if the error persists.
  
  
  Related Information:
  
  Transaction Types: In SAP, transaction types are defined in the configuration settings for asset accounting. They determine how transactions are processed and how they affect the asset's value and accounting records.

  SAP Notes: Check for any relevant SAP Notes that might provide additional insights or updates related to this error message.
  
  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 Asset Accounting for further assistance.
