  Certainly! Here's a detailed explanation for the SAP error message:
  
  SAP Error Message:
  WS_TOOL879 Function &1: &2 parameter &3 not available in system
  
  Meaning / Cause:
  This error occurs when a function module or a tool (function &1) is called or used with a parameter (&3) that does not exist or is not available in the current SAP system. Essentially, the system is trying to access a parameter that is either obsolete, incorrectly specified, or not implemented in the version of the system you are working on.
  
  &1 = Name of the function or tool being called.
  &2 = Specific function or method within the tool.
  &3 = The parameter that is missing or not recognized.
  
  This often happens when:
  
  Custom code or a third-party add-on calls a function with parameters that are not supported in the current SAP release.
  There is a mismatch between the documentation or code and the actual SAP system version.
  The function module or method has been changed or updated, and the parameter has been removed or renamed.
  Transport or upgrade inconsistencies.
  
  
  Solution / How to Fix:
  
  
  Check the Function Module or Tool Documentation:
  
  Verify the correct parameters for the function &1 and method &2 in the SAP system you are using.
  Use transaction SE37 (Function Builder) or SE80 to look up the function module and check its interface parameters.
  
  
  
  Review the Calling Code:
  
  Identify where the function &1 with method &2 is called.
  Check if the parameter &3 is being passed correctly.
  Remove or correct the parameter if it is not valid.
  
  
  
  Check SAP Notes and Support Packages:
  
  Search for SAP Notes related to WS_TOOL879 or the specific function &1.
  Sometimes SAP releases corrections or clarifications about changes in function module interfaces.
  
  
  
  System Version Compatibility:
  
  Ensure that the custom code or add-on is compatible with your SAP system version.
  If the parameter was available in an older version but removed in the current one, update the code accordingly.
  
  
  
  Debugging:
  
  Use the debugger to trace the call to the function &1 and see exactly where the parameter &3 is being referenced.
  This can help identify if the parameter is hardcoded or dynamically passed.
  
  
  
  Consult SAP Support:
  
  If the issue persists and is blocking critical functionality, raise a support ticket with SAP, providing the full error message and context.
