• What is the cause and solution for SAP error message RSDA047 - Data loss confirmed ?

  The SAP error message RSDA047 ("Data loss confirmed") typically occurs in the context of Data Warehousing, particularly when dealing with Data Transfer Processes (DTP) or when loading data into InfoProviders. This error indicates that there is a discrepancy between the data being loaded and the data structure of the target InfoProvider, which can lead to data loss.
  Causes:
  
  Data Structure Mismatch: The structure of the source data does not match the structure of the target InfoProvider. This can happen if fields are missing, or if there are incompatible data types.
  Data Type Issues: If the data types in the source and target do not match (e.g., trying to load a string into a numeric field), it can lead to data loss.
  Missing Key Fields: If key fields required for the target InfoProvider are not present in the source data, it can lead to data loss.
  Transformation Rules: If there are transformation rules that are not correctly defined, they may lead to data being dropped or not loaded correctly.
  Data Quality Issues: If the source data contains invalid or corrupt records, it may cause the DTP to fail or lead to data loss.
  
  Solutions:
  
  Check Data Structure: Ensure that the structure of the source data matches the target InfoProvider. This includes checking for missing fields and ensuring that data types are compatible.
  Review Transformation Rules: Verify the transformation rules defined in the DTP. Make sure that all necessary fields are being mapped correctly and that there are no rules that could lead to data being dropped.
  Data Quality Checks: Perform data quality checks on the source data to identify and correct any invalid or corrupt records before loading.
  Adjust DTP Settings: In the DTP settings, you can adjust the options for handling errors and data loss. For example, you can choose to log errors instead of stopping the process.
  Test with Sample Data: Before running the full data load, test the DTP with a smaller sample of data to identify any potential issues without affecting the entire dataset.
