How do I merge data from 'Epic Links' and 'Test Plans'

Hello,

I am currently working on a report where I want to show information related to Xray Tests Executed/Issues Ceated per release. Therefore, I need to merge in the rows of the table data from specifics epic links and test plans from the same release.

Then, I would be able to show in the column data, information regarding the ‘tickets created’ in the epic link during the release and also the ‘xray test executed’ in the test plans. However, I was not able to merge the epic link and test plan data, they look to have different levels that does not allow me to merge them.

Please, let me know if further information is needed, thanks!
