• What is the cause and solution for SAP error message LTR2_ES_CHECK063 - Incremental transformation uses preselection table settings 'SINGLE' ?

  The SAP error message LTR2_ES_CHECK063 indicates that there is an issue with the settings of the preselection table for an incremental transformation in SAP Data Warehousing. Specifically, it points out that the preselection table settings are set to 'SINGLE', which may not be appropriate for the incremental transformation process.
  Cause:
  The error typically arises when the system is configured to use a preselection table that is not compatible with the requirements of the incremental data load. The 'SINGLE' setting implies that only one record is being processed at a time, which can lead to inefficiencies or errors when trying to handle multiple records or when the transformation logic expects a different configuration.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Preselection Table Settings:
  
  Go to the DataSource settings in the SAP BW system.
  Verify the preselection table settings for the DataSource that is causing the error.
  Change the preselection table settings from 'SINGLE' to a more appropriate setting, such as 'MULTI', if your transformation logic supports it.
  
  
  
  Review Transformation Logic:
  
  Ensure that the transformation logic is designed to handle the type of preselection you are using. If it is designed for 'MULTI', then the preselection should be set accordingly.
  
  
  
  Test the Transformation:
  
  After making the changes, test the transformation to ensure that it runs without errors. Monitor the data load process to confirm that the incremental load is functioning as expected.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or notes related to the specific DataSource and transformation settings for additional guidance and best practices.
  
  
  
  Seek Help from SAP Support:
  
  If the issue persists after making the necessary adjustments, consider reaching out to SAP support for further assistance. They may provide insights specific to your system configuration.
  
  
  
  Related Information:
  
  Incremental Load: This refers to the process of loading only the data that has changed since the last load, rather than reloading the entire dataset. Proper configuration is crucial for performance and data integrity.
  Preselection Table: This is a temporary storage area that holds data before it is processed in the transformation. The settings here can significantly impact the efficiency of data loading.
  SAP BW/4HANA: If you are using SAP BW/4HANA, ensure that you are following the latest guidelines and best practices for data modeling and transformation.
  
  By addressing the preselection table settings and ensuring compatibility with your transformation logic, you should be able to resolve the error and successfully perform incremental transformations.
