Hey Ann,
Create the below 2 variables as measures.
- v_Max Month =If([Month]=Max([Month]) In Report) Then 1 Else 0
- v_Amt for Max Month =[Amount] Where (([v_Max Month]=1) In ([Month]))
Voila
You'll see that for all the Months & Distribution Channels, the measure v_Amt for Max Month shows the Amount from Max Month for that Distribution Channel.
Let me know if that helps.
Thanks,
Mahboob Mohammed
