MICS site attempted the SAS conversion from TS1M4 to TS1M5.  Due to some challenges encountered,  an attempt was made to revert
back to 9.4 TS1M4.  The SAS checklist was followed to restore MICS back to SAS 9.4 TS1M4.   
The first DAILY job to process since the fallback failed with a S0C4 abend in the DAY020 step.   The SASLOG contains the following:

MICS r14.1

It was determined that the MICSSDS proc was still pointing to the SAS 9.4 TS1M5 SASHELP dataset.  In reviewing the SAS conversion jobs submitted, it was determined that the 'sp.MICS.PARMS(JCLDEFC)' member was still pointing to the SAS 9.4 TS1M5 SASHELP dataset.    To resolve, the JCLDEFC member was updated to reference the SAS 9.4 TS1M4 SASHELP dataset followed by submitting the job located in 'sp.MICS.CNTL(JCLGEN0)'.   Upon completion, the PROCJOB1 job located in 'sp.MICS.CNTL' was submitted to move the updated procs to the MICS PROCLIB.    After successfully running the PROCJOB1 job, the MICSSDS proc was then inspected to verify that it is now correctly pointing to all SAS 9.4 TS1M4 datasets.
