3254095 - Defragment information is deleted when alter table split partition runs - SAP ASE

• After reorg defrag command runs on a partition, defrag_status() returns information of defragmentation operation on the partition.
  select defrag_status(db_id(), object_id('test_partition1'), partition_id('test_partition1', 'part09'))
  go

• However, when alter table split partition command runs on another partition of the same table, information of defragmentation operation from defrag_status() on that partition is deleted.
  alter table test_partition1
  split partition partnew into (part10 VALUES <= ('2022-10-31'), partnew VALUES <=(MAX))
  go
  (22 rows affected)
  
  select defrag_status(db_id(), object_id('test_partition1'), partition_id('test_partition1', 'part09'))
