• What is the cause and solution for SAP error message LAW2_MESSAGES204 - File ending &1 is not supported ?

  The SAP error message LAW2_MESSAGES204, which states "File ending &1 is not supported," typically occurs when you are trying to upload or process a file with an unsupported file extension in the SAP system. This error is often encountered in scenarios involving data uploads, file imports, or data migration processes.
  Cause:
  The primary cause of this error is that the file you are attempting to upload has an extension that is not recognized or supported by the SAP application you are using. Common unsupported file types might include files with extensions like .txt, .csv, or any other non-standard format that the system does not accept for the specific operation you are performing.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check File Extension: Verify the file extension of the file you are trying to upload. Ensure that it matches the expected format required by the SAP application.
  
  
  Convert File Format: If the file format is not supported, consider converting the file to a supported format. For example, if the system expects a .csv file, ensure that your file is saved in that format.
  
  
  Refer to Documentation: Consult the SAP documentation or help files related to the specific transaction or process you are using. This documentation often lists the supported file formats and any specific requirements.
  
  
  Use SAP Tools: If you are using a specific SAP tool (like SAP Data Services, SAP S/4HANA Migration Cockpit, etc.), check the tool's guidelines for supported file types.
  
  
  Contact Support: If you are unsure about the supported file types or if the issue persists after checking the file format, consider reaching out to your SAP support team or consulting SAP Notes for further assistance.
  
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that might address this specific error or provide additional context.
  Transaction Codes: Familiarize yourself with the transaction codes related to the process you are working on, as they may have specific requirements for file uploads.
  File Naming Conventions: Ensure that the file name adheres to any naming conventions required by the SAP system, as sometimes the issue may not just be the extension but also the overall file name format.
  
  By following these steps, you should be able to identify the cause of the error and implement a solution to successfully upload your file.
