JQL for few subtasks are not created for parent

[Manmadha Kudupudi]

Hi,

We have one parent issuetype ex: Task

When created Task then automatically should create 5 subtasks with 2 deferent summaries. (We wrote scriptrunner code to auto create 5 subtasks )

all subtasks type same - subtask

1. subtask - summary abc
2. subtask - summary abc
3. subtask - summary abc
4. subtask - summary xyz
5. subtask - summary xyx

but some Tasks are not created subtasks 4 and 5 (4. subtask - summary xyz
5. subtask - summary xyx)

Need a JQL:

I want to know which parent tasks are not creating subtasks 4&5(Summary xyz)

Advanced Thanks,
Manmadha
