Smart SAP Assistant

• What is the cause and solution for SAP error message M+023 - Delta updating is not possible in LIS ?

  The SAP error message M+023 "Delta updating is not possible in LIS" typically occurs in the context of Logistics Information System (LIS) when there are issues related to delta updates. Delta updates are used to transfer only the changes made since the last update, rather than transferring all data again, which can be more efficient.
  Causes of the Error
  
  
  Initialization Not Completed: The delta update process requires that an initialization step has been completed successfully. If the initialization has not been done, delta updates cannot occur.
  
  
  Data Source Issues: The data source from which the delta is being extracted may not be properly configured or may have issues.
  
  
  Update Mode Issues: The update mode for the data source may not be set correctly, or it may not support delta updates.
  
  
  Missing or Incomplete Data: If there are missing records or incomplete data in the data source, it can lead to issues with delta updates.
  
  
  Technical Issues: There may be technical issues with the system, such as problems with the data transfer process or issues with the underlying database.
  
  
  Solutions
  
  
  Check Initialization: Ensure that the initialization for the delta update has been completed successfully. You can do this by checking the relevant transaction codes (like RSA7 for delta queue monitoring).
  
  
  Review Data Source Configuration: Verify that the data source is correctly configured for delta updates. Check the settings in the DataSource and ensure that it is set to allow delta updates.
  
  
  Check Update Mode: Ensure that the update mode for the data source is set to a mode that supports delta updates. You can check this in the DataSource settings.
  
  
  Monitor Delta Queue: Use transaction RSA7 to monitor the delta queue. If there are records stuck in the queue, investigate the cause and resolve any issues.
  
  
  Reinitialize Delta: If necessary, you may need to reinitialize the delta process. This involves deleting the existing delta initialization and starting the process again.
  
  
  Check for Notes and Patches: Sometimes, SAP releases notes or patches that address specific issues. Check the SAP Support Portal for any relevant notes related to your version of SAP.
  
  
  Consult Logs: Review the application logs and system logs for any additional error messages or warnings that could provide more context about the issue.
  
  
  Related Information
