• What is the cause and solution for SAP error message R8349 - ALE pointers can only be assigned if DataSource uses ALE delta ?

  The SAP error message R8349, which states "ALE pointers can only be assigned if DataSource uses ALE delta," typically occurs in the context of data extraction from SAP systems using the Application Link Enabling (ALE) technology. This error indicates that there is an issue with the configuration of the DataSource in relation to the delta mechanism.
  Cause:
  
  DataSource Configuration: The DataSource you are trying to use does not support ALE delta. ALE delta is a mechanism that allows for the extraction of only the changed data since the last extraction, which is essential for efficient data transfer.
  Incorrect Delta Setup: The DataSource may not be properly set up to handle delta loads, or it may be configured for full loads only.
  Incompatibility: The DataSource might not be compatible with the ALE delta mechanism, which is required for the assignment of ALE pointers.
  
  Solution:
  
  
  Check DataSource Settings:
  
  Go to the DataSource in the SAP system (transaction code RSA1 for Data Warehousing Workbench).
  Verify that the DataSource is configured to support delta extraction. This can usually be found in the settings of the DataSource.
  Ensure that the DataSource is set up for ALE delta if you intend to use it in that manner.
  
  
  
  Use a Different DataSource:
  
  If the current DataSource does not support ALE delta, consider using a different DataSource that does. You can check the SAP documentation or consult with your SAP Basis or BW team for alternatives.
  
  
  
  Adjust Delta Configuration:
  
  If the DataSource is supposed to support delta but is not functioning correctly, you may need to reconfigure the delta settings. This could involve setting up the delta queue or ensuring that the necessary delta initialization has been performed.
  
  
  
  Consult SAP Notes:
  
  Check for any relevant SAP Notes that might address this specific error. SAP frequently updates its knowledge base with solutions for common issues.
  
  
  
  Testing:
  
  After making changes, test the DataSource to ensure that it can now handle delta loads without generating the error.
  
  
  
  Related Information:
  
  ALE and IDocs: ALE is often used in conjunction with IDocs (Intermediate Documents) for data transfer between SAP systems. Understanding how these components work together can help in troubleshooting.
  Delta Mechanism: Familiarize yourself with how the delta mechanism works in SAP BW and how it can be configured for different types of DataSources.
  SAP Documentation: Refer to the official SAP documentation for detailed information on configuring DataSources and understanding the delta process.
  
  If the issue persists after following these steps, it may be beneficial to engage with SAP support or consult with a technical expert who specializes in SAP data extraction and ALE configurations.
