ADB7127W The information about base table active versioning is not available. Check whether the base table is in a state of active versioning before applying changes.

ExplanationThe ALTER statement cannot be used to define a clone table if the base table is in a
   state of active versioning. Because the target is a data set, the information about the active
   versioning is not available. The clone table will be added by using an ALTER TABLE statement
   without dropping the base table.
System action
Processing continues.
User responseCheck whether the base table has an active versioning before applying changes. If
   active versioning is in effect, reset the versioning by running the REORG utility followed by the
   MODIFY RECOVERY utility. Then, run Compare. Alternatively, you can run Compare using the catalog
   as the target.
