Establishing checkpoints

[aluthra48]

Hello,
I have a sequence job A that calls B that calls C that calls a parallel job D. The "Do not checkpoint run" is checked on B and C only.
Now if D aborts, I expect the abort status to bubble up to C, B and A, and checkpoint should be established only at A. The question is, is that assumption correct, and if not, and C, B and A log only warning messages, no checkpoints will be set at A. Therefore how do I go about enabling the checkpoint at A to be set?
Thanks for your help.

Look at the log. Checkpoints occur when an activity completes successfully. Therefore, if A completed successfully, it will be checkpointed. On the next run of the sequence (after D fails), A will be skipped. B and C will not be skipped, because this is what "do not checkpoint run" means.
