Extracting information from second table using ID (dataset data model so measures only?)

If the entries in the Issues table are unique, i.e. it would have been a one-to-many relationship, then you can create a measure like

Created date measure = CALCULATE( SELECTEDVALUE(Issue[Created Date]), 
    TREATAS( { SELECTEDVALUE('Issue Attributes'[Issue_ID]) },Issue[Issue_ID] )
)

and put that into a visualisation with details from the Issue Attributes table

Hello there Anonymous ! Try using the TREATAS() function to apply filtering contextbetween two unrelated tables. Dont forget to use the VALUES() function the "many" side of the relationship. Something like:

Measure =
CALCULATE(
SELECTEDVALUE(Issue[Created Date]), 
TREATAS( VALUES(Issue[Issue_ID]) , 'Issue Attributes'[Issue_ID])
)

Hope this answer solves your problem!
