Everything I have read online seems to indicate it is impossible to create a Parent / Child relationship in JIra software (server) without using a plug-in or roadmaps. However, we have an existing project where there is very definitely a set up that an issue type of 'deliverable' then has children that are Epics. The epics then have user stories that are linked as issues in the Epic. Please see attachment (**edited to include this info, as failed to load the first time**).
I am being asked to replicate this structure for another project, however can not figure out how it was done. Also, whenever I use the parent link on another screen, the only projects that appear in the drop down are related to the original 'deliverable' ticket types from the project that created this ticket structure.
The person who set this up is long gone. We do not have, nor have we ever had, roadmaps or a plug in to manage ticket structure.
Does anyone know how I can:
Thanks for any assistance offered.
