• What is the cause and solution for SAP error message WS_TOOL086 - Syntax error in generated ST &1 ?

  The SAP error message:
  WS_TOOL086 Syntax error in generated ST &1
  typically occurs during the generation or activation of ABAP code, especially when working with Web Services or proxy generation tools in SAP.
  
  Cause
  
  The error indicates that the system has generated ABAP code (source code) with a syntax error.
  The placeholder &1 usually contains the name of the generated program, function module, or object where the syntax error was detected.
  This often happens during:
  
  Proxy generation (e.g., via transaction SPROXY),
  Web Service generation or consumption,
  When the generated code contains invalid ABAP statements due to:
  
  Incorrect metadata,
  Incompatible or missing data types,
  Issues in the WSDL or service definition,
  System inconsistencies or missing OSS notes,
  Custom modifications or enhancements that introduce errors.
  
  
  
  
  
  
  Solution
  
  
  Check the generated code:
  
  Go to the ABAP Editor (SE38 or SE80).
  Open the generated object mentioned in the error message (&1).
  Look for syntax errors highlighted by the editor.
  Fix the syntax errors manually if possible.
  
  
  
  Regenerate the proxy or service:
  
  Sometimes, regenerating the proxy or service after correcting metadata or WSDL issues can resolve the problem.
  Use transaction SPROXY or the relevant Web Service tools.
  
  
  
  Check the WSDL or service metadata:
  
  Validate the WSDL or service definition for inconsistencies or unsupported constructs.
  Correct any issues in the external service or metadata source.
  
  
  
  Apply relevant SAP Notes:
  
  Search for OSS Notes related to WS_TOOL086 or proxy generation errors.
  SAP often releases notes fixing known issues in proxy generation or Web Service tools.
  
  
  
  Check system consistency:
  
  Run standard SAP consistency checks.
  Ensure all required support packages and kernel patches are applied.
  
  
  
  Debug generation process:
  
  If the problem persists, debug the proxy generation or Web Service generation process to identify where the invalid code is created.
