  The SAP error message /SAPDMC/LSMW_OBJ_070025 indicates that there is a problem with the structure of the input file used in the Legacy System Migration Workbench (LSMW) process. Specifically, the error states that a field name is used more than once in the specified file, which can lead to confusion in data processing.
  Cause:
  
  Duplicate Field Names: The input file (usually a CSV or text file) contains duplicate column headers. This can happen if the file was manually edited or generated by a system that does not enforce unique field names.
  Incorrect Mapping: The mapping configuration in LSMW may not align with the structure of the input file, leading to the system expecting unique field names.
  File Format Issues: The file may not be formatted correctly, leading to misinterpretation of the field names.
  
  Solution:
  
  
  Check the Input File:
  
  Open the input file in a text editor or spreadsheet application.
  Look for duplicate column headers and ensure that each field name is unique.
  If duplicates are found, rename them to ensure uniqueness.
  
  
  
  Review LSMW Configuration:
  
  Go to the LSMW project and check the field mapping.
  Ensure that the field names in the mapping correspond correctly to the unique field names in the input file.
  
  
  
  Recreate the Input File:
  
  If the file is too complex or difficult to edit, consider recreating it from the source data, ensuring that each field name is unique.
  
  
  
  Test the Changes:
  
  After making the necessary changes, re-upload the file and run the LSMW process again to see if the error persists.
