Parent link - search one for one project type

Question

Hello! I want to set a project with ET key as a Parent link for Epic with TXL key. TXL is a different project and I wonder if project in ET can be parent for TXL Epics. Because when I search for a ET project's name, there is no such option. I can see only PBMP projects available for Parent link. Could someone help find out why parent link list doesn't show all projects in Jira? Should I set this in Parent Link configuration (even if it's locked field)? Appreciate any help!

This space is for you to change the hierarchy globally.

If you just need to add an Issue Type to your project, follow this page: Add, edit, and delete an issue type

Let me know if you have questions

I found settings where I need to add 'Project' issue type to hierarchy level. When I clicked Save it showed me this message. Does it mean that existing Parent links may be broken even though I am not removing any issue types from hierarchy or is this just warning sign in case I remove any of issue types?

The hierarchy is defined by Jira's global interface.

Click the admin gear icon > Click 'Issue type Hierarchy' and adjust the hierarchy for Jira. Note that changing the hierarchy will affect the Issue Type structure in all other projects where he may be involved
