Description

This function specifies whether an elementary symbol is set to active or inactive.

By default, this function checks whether the necessary user authorization is available so that an elementary symbol can be displayed as active in the faceplate.

You can find the function in the stdlib_hook_project.ctl under wincc_oa_path/Stdlib_3.20/scripts/libs/

  if(sUser=="")
  sUser = getUserName();
  return hasUserAuthorization(sDpe, sUser);
  //if you don't want to use permission check
  //return true;
