we have additional levels of hierarchy in our jira ,
and logged hourse for stories and sub tasks
is it possible to show the sum of looged hourse on project level ?
Unfortunately this currently is not available, but is something we are looking at adding very soon. Once the work log field is available on lookup issues (see https://support.atlassian.com/jira-software-cloud/docs/automation-actions/#Automationactions-Lookupissues for the current list of available fields), then you will be able to do what you are wanting.
