Hello @Oksana_Dovha
It seems that you reached out to us directly.
I’m posting a possible solution here in case other eazyBI users face a similar problem.
For this use case, the import of the inherited field dimension might be useful.
Here is a documentation that explains how to Import the inherited field dimension: JavaScript calculated custom fields
And here is a community post about a similar use-case - Calculating Total user stories based on epics fields - #2 by janis.plume
Best wishes,
