As you can see in the tables below I am trying to show only the rows with the latest Claim transaction sequence number. I have tried many ways to no avail can someone help please.
Try something similar to my solution from this post - obviously replacing the Date with your ClaimTransactionSequence to drive the sorting.
Essentially you're creating a flag in the load script for the most recent (in your case highest valued) date / Transaction which will then allow you to use an 'if' in the table to exclude all rows without the flag.
