Hi @radimdrinka,
Sorry for the delayed answer!
You need to import custom field changes and then use issue change history measures. To get the timestamp when the value has been changed first to some particular value, you can use this calculation:
TimestampToDate(
([Transition Field].[Team],
[Team].[KS],
[Measures].[Transition to first timestamp])
)
To see if the value was changed from KS, you can use this calculation:
(
[Measures].[Transitions from],
[Transition Field].[Team],
[Team].[KS]
)
best,
