How to prevent Creation an specific issue type under Epic ?

[GabrielJ]

Currently, I did not found a method to restrict creation of a specific Issue Type ("Theme") under Epic.

I tried to use the following without success:

Only if the following boolean expression is true: %{Issue type}= "Theme" IMPLIES %{Parent's Epic Link} = NULL Message to show when validation fails: "".

I apologize. My mistake, it works fine.

Sorry again, I thought it was fixed but not. My original question is still pending

Hi @gabyj,

You should use field Epic Link instead of Parent's Epic Link.

Use the following boolean expression:

%{00014} = "Theme" IMPLIES %{nnnnn} = nul

replacing nnnnn with field code for Epic Link.
