    Hey community_pinki ,

     

    when you have a many to many relationship a lookup will not give you a clear answer.

    It's like I ask you "It's January, what year is it?". 

     

    But you can for example do a MAX of the URL:

    ImageURL Column =
VAR vCastID = Creator_Data[CastID]
RETURN
    CALCULATE(
        MAX( Creator_ImageTable[Image URL] ),
        Creator_ImageTable[CastID] = vCastID
    )

     

    If you need any help please let me know.
    If I answered your question I would be happy if you could mark my post as a solution ✔️ and give it a thumbs up 👍
     
    Best regards
