Checkpoint restart

[luie]

benny.lbs' case happens to us too and restart only works for 1 level down the top sequence. When one of the grandchildren fails, all the jobs under the level 2 that finished successfully prior to the abort runs again when restarted. All our sequences have these properties:
-'Add checkpoints..' is enabled.
-'Automatically handle activities that fail..' is enabled.
-All job activities have 'Reset if required then run' option.
-'Do not checkpoint run' for each job activity is disabled.
-All the routine activites return 0 on success.
-We do not have exception handler.
It seems that DataStage treats the level 2 abort as the point of failure ?!?
