Exclude parent Work item if the child Work item summary has specific Text

Hello Team,
I am trying to generate a JRS report to Exclude parent Work item if the child Work item summary has specific Text.
So It Should List only a Parent Work item whose Children Summary does not contain Specific text say "ABC 100"
Please help with query . How can it be solved?
Whether JRS is feasible or RPE? If JRS how the Query should go. If RPE any template available?
Appreciate for Quick help.
Thanks,
