  In the DB2 Object Comparison Tool, when comparing source
  source PBG/PBR table space, or partitioned table space with
  target segmented or simple table space which contains multiple
  tables, Compare generates the following warning message in the
  report indicating changing the table space type could fail when
  the table space has more than one table.
  
  (W)If the segmented tablespace has more than one table,
  changing the segmented table space to a >table space type<
  tablespace will fail.
  
  However, Compare still ends successfully with return code 0,
  and generates the APPLY job. Running the APPLY job could
  result in an error in some cases.
  
  For example, on DB2 10, when comparing target multiple-table
  segmented or simple table space with source PBG table space,
  DB2 Object Compare generates an 'ALTER TABLESPACE >tsname<
  MAXPARTITIONS nn' statement in the APPLY job which will result
  in a SQLCODE=-650/SQLCODEN650 error:
  
  DSNT408I SQLCODE = -650,
  ERROR:  THE ALTER STATEMENT CANNOT BE  EXECUTED,
  REASON 10
  

Problem conclusion

• Problem has been resolved. Here is the summary of the Compare
  behavior when comparing source PBG/PBR or partitioned table
  space which can only have 1 table with target simple or
  segmented table space which contains more than 1 table with:
  
  1. On DB2 10 New Function Node (NFM), DB2 supports changing
  segmented or simple table space which has only one table to a
  PBG table space using ALTER. To be consistent with the DB2
  behavior, In this case, compare will generate an ALTER statement
  in the APPLY job. However, if the target table space contains
  multiple tables, to prevent a run-time error during
  running APPLY, Compare will issue an error message
  ADB7156E and end with return code 8.  The APPLY job
  will not be generated.
  
  ADB7156E The >segmented/simple< tablespace has more than
  one table, changing the tablespace to a >table space type<
  tablespace will fail. Number of tables is: >table number<.
  
  2. For the other cases, converting segmented or simple table
  space to PBG/PBR or partitioned table space needs to be
  accomplished by a DROP/CREATE of the table space.  Under
  these conditions, Compare will generate DROP/CREATE statements
  in the APPLY job to implement the changes. When the target
  simple or segmented table space contains multiple tables,
  Compare will generate a warning message ADB7157W and end with
  return code 4.  Compare will generate the APPLY job and user
  could update to keep only the table that is needed.
  
  ADB7157W The >segmented/simple< tablespace has more than one
  table, changing the tablespace to a >table space type<
  tablespace may fail. Number of tables is: >table number<.
