  WEBI_CHECKS024 Serv, Def. &1, Function &2, Param. &3, Type &4: wrong optionality
  Explanation / 
  Cause:

  Common scenarios causing this error:
  
  Custom functions or user-defined functions with incorrect parameter definitions.
  Upgrading or patching WebI or the BI platform where function definitions have changed but reports or universes still use
