• What is the cause and solution for SAP error message W3_TOOL121 - Conversion Error. Incorrect Display. Watch Long Text. ?

  SAP Error Message:
  
  W3_TOOL121 Conversion Error. Incorrect Display. Watch Long Text.
  
  Cause:
  This error typically occurs when there is a problem with the conversion or display of long text fields in SAP, especially in Web Dynpro or SAP GUI environments. The system encounters difficulties converting or rendering the long text content properly, which can be due to:
  
  Incorrect or missing text object or text ID references.
  Issues with the text encoding or character set.
  Problems in the underlying function modules or classes responsible for fetching or displaying long texts.
  Incompatibility or bugs in the UI component (e.g., Web Dynpro component or SAP GUI version).
  Corrupted or inconsistent long text entries in the database.
  
  
  Solution:
  
  
  Check Text Object and Text ID:
  
  Verify that the correct text object and text ID are used when fetching the long text.
  Ensure that the long text exists for the given object and ID.
  
  
  
  Review Code or Configuration:
  
  If custom code or enhancements are involved, debug the part where the long text is retrieved and displayed.
  Use standard SAP function modules like READ_TEXT or classes like CL_TEXT_DOCUMENT properly.
  Make sure the parameters passed to these functions are correct.
  
  
  
  Check Character Encoding:
  
  Ensure that the system and UI components handle the character encoding correctly.
  Sometimes, switching the GUI or browser encoding settings can help.
  
  
  
  Update or Patch SAP Components:
  
  Check for SAP Notes related to this error message.
  Apply relevant patches or support packages if the issue is due to a known bug.
  
  
  
  Test in Different Environments:
  
  Try displaying the long text in SAP GUI vs. Web Dynpro to isolate if the problem is UI-specific.
  If the problem occurs only in Web Dynpro, check the UI element properties and data binding.
  
  
  
  Database Consistency:
  
  Run consistency checks on the long text tables (e.g., STXH, STXL).
  Repair or re-import texts if corruption is detected.
