I have two types of issues - 'Contract' and 'Sys HLR'.
'Sys HLR' are always children of 'Contract'
I would like to have a query of all 'Contract' issues which don't have a linked (child issue) of 'Sys HLR'.
I saw an option of issueFunction not in parentsOf ("issuetype = ABC") and tried to apply it like that:.
Type = 'Contract' and issueFunction not in parentsOf ("issuetype = 'Sys HLR'")
But it did not work.
How should I write it?
