  The SAP error message "42801 &1 with &2 results in an empty file extension" typically indicates an issue related to file handling, particularly when the system is trying to generate or process a file but encounters a problem with the file extension.

  Check File Name Configuration: Review the configuration settings related to file generation in the relevant transaction or program. Ensure that the file name is being constructed correctly and includes a valid extension.
  Validate Input Data: Ensure that the data being processed contains all necessary fields, including those that may contribute to the file name and extension.
  Modify Program Logic: If you have access to the ABAP code, check the logic that generates the file name. Ensure that it correctly appends a valid extension based on the file type being created.
  Test with Different Data: If possible, test the process with different sets of data to see if the issue persists. This can help identify if the problem is data-specific.
