• What is the cause and solution for SAP error message W8200 - Internal error in HTML generation: Line length exceeded (&) ?

  SAP Error Message:
  
  W8200 Internal error in HTML generation: Line length exceeded (&)
  
  Cause:
  This error occurs during the generation of HTML output in SAP when a line exceeds the maximum allowed length. SAP's HTML generation engine has a limit on the length of a single line in the generated HTML code. If this limit is exceeded, the system raises this internal error.
  Common scenarios causing this include:
  
  Very long strings or URLs without breaks.
  Large amounts of data concatenated into a single line.
  Custom code or standard SAP programs generating HTML output with very long lines.
  Long text fields or data dumps being output directly into HTML without proper formatting or line breaks.
  
  
  Solution:
  To resolve this error, consider the following approaches:
  
  
  Check and Modify the Code Generating HTML:
  
  Identify the program or report generating the HTML output.
  Insert line breaks or split long strings into smaller chunks before output.
  Use appropriate formatting functions to ensure no single line exceeds the length limit.
  
  
  
  Use SAP Standard Functions for HTML Generation:
  
  Instead of manual string concatenation, use SAP's standard classes or function modules designed for HTML output, which handle line length internally.
  
  
  
  Adjust Long Text Handling:
  
  If the error is caused by long text fields, process the text to insert line breaks or wrap text properly before output.
  
  
  
  Check for OSS Notes:
  
  Search SAP OSS Notes for any patches or corrections related to this error message or HTML generation issues in your SAP version.
  
  
  
  Debugging:
  
  Use the debugger to trace where the HTML generation fails.
  Look for variables or strings that are unusually long and adjust accordingly.
  
  
  
  
  Related Information:
  
  
  SAP Note References:
  
  Sometimes SAP releases notes addressing internal errors in HTML generation. Check the SAP Support Portal with keywords like "W8200 Internal error in HTML generation" or "Line length exceeded".
  
  
  HTML Line Length Limits:
  
  The internal SAP HTML generator has a line length limit (often around 255 or 512 characters). Exceeding this causes the error.
  
  
  Common Modules Involved:  
  
  Classes like CL_GUI_HTML_VIEWER or function modules related to HTML output.
  Custom reports or ALV outputs that export to HTML.
  
  
  
  Workaround:
  
  If immediate fix is not possible, try exporting data in a different format (e.g., Excel, PDF) instead of HTML.
  
  
  
  Summary:
  The error "W8200 Internal error in HTML generation: Line length exceeded (&)" is caused by generating an HTML line longer than SAP's internal limit. Fix it by splitting long lines, inserting line breaks, or using SAP's standard HTML output methods. Check for SAP Notes and debug the code generating the HTML output for long strings.
