Diagnosis

• You assigned more than one output stream in a stage
formula (only one output stream is permitted in a stage formula).
Or

• You assigned an input stream for which no output stream
exists in a different stage formula.

Procedure


• If you assigned more than one output stream, delete the
entry for the stream.
Or

• Before you use an input stream in a stage formula, assign
it as an output stream in a different stage formula.
