• What is the cause and solution for SAP error message LTR2_ES_CHECK064 - Incremental transformation will use preselection table settings 'SINGLE' ?

  The SAP error message LTR2_ES_CHECK064 indicates that during an incremental transformation process, the system is defaulting to use the preselection table settings as 'SINGLE'. This typically occurs in the context of SAP Data Warehousing or SAP BW (Business Warehouse) when dealing with data extraction and transformation processes.
  Cause:
  The error message is generally triggered due to the following reasons:
  
  
  Preselection Table Settings: The system is configured to use a preselection table that is set to 'SINGLE', which may not be optimal for the current transformation process. This can happen if the settings are not properly configured for the data source or if the transformation logic is not aligned with the expected data flow.
  
  
  Data Source Configuration: The data source from which the data is being extracted may not be set up correctly, leading to the system defaulting to a less efficient mode of operation.
  
  
  Transformation Logic: The transformation rules defined in the process may not be compatible with the expected data handling, causing the system to revert to a basic setting.
  
  
  Solution:
  To resolve this issue, you can take the following steps:
  
  
  Check Preselection Table Settings:
  
  Navigate to the transformation settings in the SAP BW system.
  Review the preselection table settings and ensure they are configured correctly. If 'SINGLE' is not appropriate, consider changing it to 'MULTI' or another suitable option based on your data requirements.
  
  
  
  Review Data Source Configuration:
  
  Ensure that the data source is correctly configured and that all necessary fields and settings are properly defined.
  Check for any inconsistencies or missing configurations that could lead to the defaulting behavior.
  
  
  
  Examine Transformation Logic:
  
  Review the transformation rules and logic to ensure they align with the data extraction and loading requirements.
  Make adjustments as necessary to ensure that the transformation can utilize the preselection table effectively.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or notes related to the specific version of SAP BW you are using. There may be specific guidelines or updates that address this issue.
  
  
  
  Testing:
  
  After making changes, perform a test run of the transformation to ensure that the error does not reoccur and that the data is being processed as expected.
