• What is the cause and solution for SAP error message >U104 - Error in file: The first data record must be type 0 (line &1) ?

  The SAP error message U104 indicates that there is an issue with the format of the data file being processed. Specifically, the error message states that the first data record in the file must be of type 0, but it is not. This typically occurs during data uploads or when processing files in SAP, such as during the use of the BAPIs, IDocs, or other data import methods.
  Cause:
  
  Incorrect File Format: The file being uploaded does not conform to the expected format. The first record should be of type 0, but it may be of a different type (e.g., type 1, type 2, etc.).
  Data Corruption: The file may be corrupted or improperly formatted, leading to the first record being misinterpreted.
  Misconfiguration: The configuration settings in SAP for processing the file may not match the structure of the incoming data.
  
  Solution:
  
  Check File Structure: Open the file in a text editor or spreadsheet application and verify that the first record is indeed of type 0. The structure should match the expected format defined in the SAP documentation.
  Correct the Data: If the first record is not of type 0, modify the file to ensure that the first record is correctly formatted. This may involve changing the record type or adjusting the data.
  Review Configuration: Check the configuration settings in SAP related to the data import process. Ensure that they align with the structure of the file being uploaded.
  Test with Sample Data: If possible, create a small sample file that adheres to the expected format and test the upload process with that file to confirm that the issue is with the original file.
  Consult Documentation: Refer to the relevant SAP documentation or guides for the specific data import method you are using to ensure compliance with the expected file format.
