Running MICS with mixed levels of SAS
The SAS libraries used by MICS were updated to a newer version but the SASHELP dataset being used was still referencing old version.
Ensure that all SAS datasets used by MICS are converted to the new release. MICS cannot run with mixed levels of SAS.
Follow the conversion checklist Converting MICS to a New SAS version when upgrading from an older to a newer version of SAS (for example, 9.4.0M0 to 9.4.0M8).
Refer to Updating MICS for SAS System Changes when changing the SAS System Library names, typically associated with application of SAS System maintenance.
