Errors similar to the following will be generated if PROC REPORT code contains a computed variable or a variable that does not exist in the data set, and the output is directed to the SASREPORT destination:

ERROR:  BRIDGE FAILURE CALLING UNKNOWN.
ERROR:  SUBSYSTEM 156 NOT INSTALLED.
ERROR: Unable to load transient module (Bridge failure).
NOTE: The SAS System stopped processing this step because of errors.
ERROR:  BRIDGE FAILURE CALLING UNKNOWN.
ERROR:  SUBSYSTEM 156 NOT INSTALLED.

ERROR:  Read Access Violation In Task [ Submit )
Exception occurred at (66412582)
Task Traceback

To circumvent the problem, remove the computed or non-existent variable, or direct the output to another destination, such as HTML, PDF, or RTF.

Please see the Full Code tab for an example of code that will replicate the problem, and an example of a workaround.
