  SAP Error Message:
  W3_TOOL077 No documentation exists for the function &
  
  Cause:
  This warning message occurs when you try to access the documentation for a particular function module or function in SAP, but no documentation has been created or maintained for that function. The placeholder "&" in the message is replaced by the name of the function for which documentation is missing.
  In other words, the system is informing you that the function module or function you are trying to get help or documentation for does not have any associated documentation in the SAP system.
  
  When does it occur?
  
  When you use transaction SE37 (Function Builder) or SE80 (Object Navigator) and try to display the documentation of a function module.
  When you try to access the documentation via the function module interface or from within ABAP code or tools that link to function documentation.
  When you use tools or reports that attempt to extract or display function documentation.
