• What is the cause and solution for SAP error message DU021 - Only files with a record length of < 4096 bytes can be imported ?

  The SAP error message DU021 indicates that the system is unable to import a file because its record length exceeds the maximum allowed limit of 4096 bytes. This error typically occurs during data import processes, such as when using the Data Transfer Workbench (DTW) or other data import tools.
  Cause:
  The primary cause of the DU021 error is that the file being imported contains records that are longer than 4096 bytes. This can happen due to:
  
  Incorrect file formatting.
  Data fields that exceed the expected length.
  Use of delimiters or line breaks that result in longer records.
  
  Solution:
  To resolve the DU021 error, you can take the following steps:
  
  
  Check File Format: Ensure that the file you are trying to import is in the correct format (e.g., CSV, TXT) and adheres to the expected structure.
  
  
  Review Record Length: Open the file in a text editor or a spreadsheet application to check the length of each record. If any record exceeds 4096 bytes, you will need to modify it.
  
  
  Split Long Records: If you find records that are too long, consider splitting them into multiple records or truncating the data to fit within the limit.
  
  
  Adjust Data Fields: Review the data fields in your file. If certain fields are unnecessarily long, consider shortening them or removing any extraneous data.
  
  
  Use a Different Import Method: If the data is too complex or large, consider using a different method for importing the data, such as using a custom program or script that can handle larger records.
  
  
  Consult Documentation: Refer to the SAP documentation for the specific import tool you are using to ensure you are following the correct guidelines and limitations.
  
  
  Related Information:
  
  SAP Notes: Check SAP Notes for any updates or patches related to data import issues.
  Data Transfer Workbench (DTW): Familiarize yourself with the DTW tool and its limitations regarding file formats and record lengths.
  File Encoding: Ensure that the file encoding (e.g., UTF-8, ANSI) is compatible with SAP's requirements, as this can also affect record length.
  
  By following these steps, you should be able to resolve the DU021 error and successfully import your data into SAP.
