  The SAP error message AC055, which states "Transaction type & is not defined," typically occurs in the context of Asset Accounting (FI-AA) when a transaction type that is being used in a transaction is not defined in the system. This can happen during various processes, such as posting asset transactions or running reports.
  Cause:

  Check Configuration:
  
  Go to the configuration settings in SAP for Asset Accounting.
  Navigate to Financial Accounting (New) > Asset Accounting > Transaction Types.
