If you have specified incorrect parameters for your function, this error message
will appear. For example, the Cognos Transformer-specific share function requires
the first parameter to be a child category of the second parameter. Reversing the
order of the child and parent categories within this function causes an error in the
predefined syntax.
Procedure
For more information about the syntax of supported Cognos Transformer
functions, see "Functions" on page 357.
