How to create such a hierarchy in Structure?

Question

Hello!
In our new project, we decided to use Epic how a container for collect issues by the link. Epic is a big module of a system. Now our hierarchy looks like:

M – Epic
A – Story
BE-A, BE-B – Tasks

Story and Tasks have an epic link. This is very helpful in working with the backlog.
Tasks have a "block" link. This allows us to use the "Extend transformation".
But this leads to the appearance of duplicates.

What's wrong? How can I save Epic link and remove duplicates?
Help me, please! I can't think about it anymore. I want to sleep :)

PS: Structure v 4.0.0

Hi Alexandr,

If the only difference between BE-A and BE-C is that BE-A links to Story A, then there is still a way to realize what you need. For that you would have to Insert stories and tasks, then extend by linked issues, then filter to Remove Inserter/Extender duplicates, this will remove BE-A from the root. Then, group by Epic. This should create a hierarchy you describe.

Please, let me know if this works for you.

Regards,
Egor

@Egor Tasa [ALM Works], thank you for the fast answer!

If I understand you correctly, all the ways assume that I'm hide all Tasks from level under Epics.

Sorry, but I didn't specify one point. Not every Task must be under the Stories.
For example, Task BE-C can under Epic M:

* BE-C has epic link to Epic M
* BE-C hasn't links to any Stories

The correct example of the hierarchy in the question was to look like this:

M1
– BE-A
– BE-C
– A
– – BE-A
M2
– BE-D

I want hide BE-A under Epic M1, but show under Story A.

Sorry for my English. I hope you understand, what I need)
