• What is the cause and solution for SAP error message MCEX149 - Entries still exist in system &1 in the table MC12_PUFFER -> ?

  The SAP error message MCEX149 indicates that there are still entries in the table MC12_PUFFER that are preventing the completion of a certain process, typically related to the Material Management (MM) or Production Planning (PP) modules. This error often arises during the execution of a transaction that requires the clearing or deletion of temporary data, but the system finds that there are still entries present in the specified table.
  Cause:
  The primary cause of this error is that the system is trying to perform an operation (like deleting or archiving) that requires the MC12_PUFFER table to be empty, but there are still entries in that table. This can happen due to:
  
  Incomplete or failed previous processes that did not clear the buffer.
  Data inconsistencies or issues in the system that prevent the buffer from being cleared.
  Ongoing processes that are still using the data in the buffer.
  
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Check the Entries in the Table:
  
  Use transaction code SE11 (Data Dictionary) or SE16 (Data Browser) to view the contents of the MC12_PUFFER table.
  Identify the entries that are causing the issue.
  
  
  
  Clear the Buffer:
  
  If the entries are no longer needed, you can manually delete them from the MC12_PUFFER table. However, be cautious with this approach, as it may affect ongoing processes.
  You can also use transaction code MC12 to process the data in the buffer, which may help in clearing it.
  
  
  
  Check for Ongoing Processes:
  
  Ensure that there are no ongoing processes that are using the data in the buffer. If there are, you may need to wait for those processes to complete.
  
  
  
  Run Consistency Checks:
  
  If you suspect data inconsistencies, you can run consistency checks or use transaction codes like MCEX to check for errors in the related processes.
