• What is the cause and solution for SAP error message CNV_DMC_MD_EXTRACTOR019 - Data sheet &1, line &2: the data row contains more cells than expected ?

  The SAP error message CNV_DMC_MD_EXTRACTOR019 indicates that there is an issue with the data extraction process, specifically related to the format of the data being processed. The message states that a data row in the specified data sheet contains more cells (or columns) than expected. This typically occurs during data migration or extraction processes, such as when using the SAP Data Migration Cockpit or similar tools.
  Cause:
  
  Mismatch in Data Structure: The data row may have more columns than the target structure defined in the migration template. This can happen if the source data has additional fields that are not accounted for in the target structure.
  Incorrect File Format: The file being processed may not be in the expected format (e.g., CSV, Excel) or may have been modified incorrectly, leading to extra columns.
  Data Entry Errors: Manual data entry errors can lead to additional delimiters or separators being included in the data, resulting in more cells being detected.
  Template Changes: If the data extraction template has been modified after the data was prepared, it may lead to discrepancies in the expected number of columns.
  
  Solution:
  
  Check the Data Template: Verify that the data template you are using matches the expected structure. Ensure that the number of columns in the data sheet corresponds to the number of fields defined in the migration template.
  Review the Data File: Open the data file in a text editor or spreadsheet application to inspect the rows and columns. Look for any extra delimiters or unexpected data that may be causing the issue.
  Remove Extra Columns: If there are extra columns in the data file that are not needed, remove them to match the expected structure.
  Validate Data Format: Ensure that the data file is saved in the correct format (e.g., CSV, XLSX) and that it adheres to the expected encoding and delimiter settings.
  Test with Sample Data: If possible, create a small sample data file that adheres to the expected structure and test the extraction process with it to ensure that the issue is resolved.
