Filtering Epic to a specific Board by adding a label

[Ibo]

Hi Jira Community,

I've a question regarding filtering Epics in Jira to a specific Board by adding a label to an Epic.

Starting what we've:

We've 1 Project and within the Project we've 1 "Epic Board" and 3 "Team Boards" as follows

• Board 1: Contains all Epics
• Board 2: Contains Epics of Team A
• Board 3: Contains Epics of Team B
• Board 4: Contains Epics of Team C

We gather all Epics in our Board 1. Later then, we assign each Epic to one of the Board 2 - 4. To assign an Epic to one of the Board 2 - 4, we add the specific Epic number to the filter which is connected to one of the Board 2 - 4.

This works fine, but we would like to assign an Epic automatically to one of the specific Board 2 - 4 by adding a specific Label to the Epic.

What I try to do:

To assign an Epic automatically to one of the particularly Board, I've created 2 filters as follows:

Filter 1 Team A
project = PKEY AND labels in (TeamA) ORDER BY RANK ASC

Filter2 Team A
issuefunction in linkedIssueOfAllRecursive("project = PKEY AND labels in (TeamA)") ORDER BY RANK ASC

"Filter 2 Team A" is connected to Board 2. If I click on search of "Filter2 Team A", not all of the expectable 30 Epics are shown, only 10 Epics of them. The other 20 is not shown. What is noticeable is, that 20 Epics which are not shown, were created last days. Even curious is, that in "Filter 1 Team A" all expectable 30 Epics are shown. I don't know why.

My questions to you

• Do you know, why not all 30 Epics are shown in "Filter2 Team A"?
• Is there a better solution for my approach? 

Thank you very much in advance for supporting!
