Hi @CountingPeople ,
Do you mean that the top 5 accounts in mid-October will not appear in mid-November. Re-sort them?
Or the account that appeared in mid-October will also appear in the follow-up:
_rank <=5,MAX('Table'[Amount]) ,BLANK())
Can you share sample data and sample output in table format? Or a sample pbix after removing sensitive data. We can better understand the problem and help you.
