After APPLY a maintenance of the R18, i must do the Compare , create object and a bind plan and packages, but the job ssid0000 (compare object) generate a file DB2?DDL which is different from the one of another environment, even if the table PTI.PTMGB_APTABLE_0100 is different (this table was changed) : it means the job should generate the right DDL to drop and recreate the table with a new column.
thank you for help
