Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• DB2 Administration Tool for z/OS reports problem with ALTER on
  TEMPORAL TABLE because an un-needed DROP VERSIONING statement is
  generated. Similar problem exists in DB2 Object Compare Tool for
  z/OS, and the history table should be treated as a dependent
  object (like indexes) and therefore be compared.
  .
  Example of extraneous statement:
    DDL    ALTER TABLE MFSMFX4.ABC DROP VERSIONING
  .
