• What is the cause and solution for SAP error message CMCB_MSG090 - Incorrect first line ?

  The SAP error message CMCB_MSG090 "Incorrect first line" typically occurs in the context of data import or file processing within SAP systems, particularly when dealing with file formats or data uploads. This error indicates that the first line of the input file does not conform to the expected format or structure.
  Cause:
  
  File Format Issues: The first line of the file may not match the expected header format. For example, if the system expects a specific delimiter (like a comma or tab) or specific column names, any deviation can trigger this error.
  Encoding Problems: The file may be saved in an incorrect encoding format (e.g., UTF-8 vs. ANSI), which can lead to misinterpretation of the first line.
  Empty or Corrupted File: If the file is empty or corrupted, the system may not be able to read the first line correctly.

  Solution:
  
  Check File Format: Ensure that the first line of the file matches the expected format. This includes checking for the correct delimiter and ensuring that the column names are spelled correctly and in the right order.
  Verify Encoding: Make sure the file is saved in the correct encoding format. If necessary, convert the file to the required encoding (e.g., UTF-8).
  Inspect the File: Open the file in a text editor to check for any hidden characters, extra spaces, or formatting issues that might not be visible in other applications.
  Test with Sample Data: Create a small sample file that adheres to the expected format and test it to see if the error persists. This can help isolate whether the issue is with the specific file or the system configuration.
