Transition Author of Custom Field

I have a cascading select custom field, “Root Cause Selection”. The import from Jira is set up as:

I would like to have a report that lists the Transition Author and the date the selection was made. I have been able to get everything but the Transition Author.

Where the measure RootCause is:
Both Project and Status listed are aggregates I use often.

(
  [Project].[NonQA Projects],
  [Issue Type].[Defect],
  [Status].[PreTestReadyDefects],
  [Measures].[Issue Root Cause Selection]
)

Date set is:

TimestampToDate(
  (
    [Measures].[Transition to last timestamp],
    [Transition Field].[Root cause selection]
  )
)

and Set by is:
[Transition Author].[User].Name


I have tried:
1: Using the Transition Author dimension in the Rows
This causes the report to time out
2: Variations of the above measure (i.e. CurrentMember, CurrentHierarchyMember, etc) with and without listing [Transition field].[Root Cause Selection]
Naming the transition field causes the column output to go blank.


Please tell me what I am missing, OR if it’s just not possible, I would love some validation on that so I can stop trying :slight_smile:

THANK YOU eazyBI support team!!

Looks like the Transition Author (displayed here as “Set By”) can only be displayed when set in a row under the target custom field (at least for this custom field).
