• What is the cause and solution for SAP error message RSAN_RT602 - Wrong file format in &1. Loss of information in line &2, (&3->&4) ?

  The SAP error message RSAN_RT602 indicates that there is a problem with the format of a file being processed in the context of SAP BW (Business Warehouse) or SAP BI (Business Intelligence). This error typically arises when the system encounters unexpected data formats or structures in the input file, which can lead to data loss or corruption.
  Cause:
  
  
  Incorrect File Format: The file being processed does not match the expected format. This could be due to:
  
  A mismatch in delimiters (e.g., using commas instead of tabs).
  Incorrect data types in specific columns (e.g., text in a numeric field).
  Missing headers or additional unexpected rows.
  
  
  
  Corrupted File: The file may be corrupted or improperly generated, leading to unreadable content.
  
  
  Data Encoding Issues: The file may be encoded in a format that SAP cannot interpret correctly (e.g., UTF-16 instead of UTF-8).
  
  
  Line Breaks or Special Characters: Unexpected line breaks or special characters in the data can also cause this error.
  
  
  Solution:
  
  
  Check File Format: Ensure that the file adheres to the expected format. Verify:
  
  The correct delimiter is used.
