AX批处理任务不会根据依赖性运行 / AX Batch task does not run according to dependencies

We have a batch job, during runtime, it will create several batch tasks, among these task, some of them should run first and some of them will run concurrently, task dependencies are added during runtime.

We did a lot of testing, but occasionally when this happen, we have no idea what has cause it even though the job looks entirely alright, after spending some time on it, we raised a support call with MS Support, this issue has been reported before and it can be found at Partner Source support knowledge base.

Search for KB 2731538 or the subject line "Batch framework does not respect task dependencies in Microsoft Dynamics AX 2009 Service Pack 1", you'll need to download and apply the hotfix.
