If there are errors or severe error messages during JCL checking, CA JCLCheck does not produce a graph. This is a safety measure that safeguards against the documentation of errors and other significant problems in the graph.
When simulating condition code checking or restarting, CA JCLCheck only graphs those steps simulated to execute. It does not graph the skipped steps and issues a warning message.
You can allocate a SYSGRAPH DD statement that allows use of the GRAPH option with a TSO CLIST or the CA JCLCheck ISPF Interface.
