  SAP Message: W3_TOOL023 - Blank line(s) inserted
  
  Cause:
  This message typically occurs during the processing of ABAP code or when using SAP development tools (such as the ABAP Editor or Code Inspector). It indicates that the system has automatically inserted one or more blank lines into the source code.
  The insertion of blank lines can happen for several reasons, including:
  
  Formatting adjustments: The SAP tool or editor is trying to improve the readability or structure of the code by inserting blank lines.
  Syntax or parsing requirements: Certain statements or constructs require separation by blank lines for correct parsing or to meet syntax rules.
  Code generation or transformation: When code is generated or transformed (e.g., during code templates, refactoring, or code cleanup), blank lines may be inserted automatically.
  Line length or continuation handling: To handle long lines or continuation lines, blank lines might be inserted.
  
  This message is generally informational and not an error that stops processing.
  
  Solution:
  
  Review the inserted blank lines: Check the source code around the indicated location to understand why blank lines were inserted.
  Accept the formatting: Usually, this message is harmless and can be ignored if the inserted blank lines do not affect program logic.
  Manual adjustment: If the blank lines are undesirable, you can manually remove them in the ABAP Editor, but be cautious not to break syntax or readability.
  Check code templates or generation logic: If the blank lines are inserted during code generation or templates, review the template or generation logic to control formatting.
  Use SAP recommended formatting: Follow SAP's recommended code formatting guidelines to minimize such automatic insertions.
