When you use the REACH statement with GRAPH_INTERNAL_FORMAT=THIN, PROC OPTGRAPH stops processing, and returns an exception:

ERROR:  An exception has been encountered.
Please contact technical support and provide them with the following traceback

To avoid the problem, do not specify the GRAPH_INTERNAL_FORMAT= option (so that the default value, GRAPH_INTERNAL_FORMAT=FULL, is used instead).

Note: The default value, GRAPH_INTERNAL_FORMAT=FULL, requires more memory, so PROC OPTGRAPH might return an out-of-memory error for large data sets.
