  The SAP error message B1066, which states "Messages have been created during processing (last was displayed)," typically indicates that there are messages or warnings generated during the execution of a transaction or process in SAP. This message is often seen in the context of batch processing, background jobs, or when executing certain transactions that may generate multiple messages.
  Cause:
  
  Multiple Messages: The system has generated multiple messages (info, warning, or error) during the processing of a transaction. The last message is displayed, but there may be others that were generated earlier.
  Batch Processing: If you are running a batch job or a mass transaction, it may produce several messages based on the data being processed.

  Data Issues: The data being processed may have inconsistencies or issues that trigger messages.

  Check Message Log: Review the message log to see all messages generated during the processing. You can usually find this in the transaction where the error occurred or by using transaction codes like SLG1 (Application Log) or SM21 (System Log).
  Analyze Messages: Look at the details of the messages to understand their nature (info, warning, error) and take appropriate action based on their content.
  Correct Data Issues: If the messages indicate data issues, correct the data and reprocess the transaction.
  Adjust Configuration: If the messages are due to configuration settings, consult with your SAP Basis or functional team to adjust the settings as necessary.
  Re-run the Process: After addressing the issues, re-run the transaction or batch job to see if the messages persist.
