hi community,
transactions is a numbered list and module has 3 line items, 2 are text and 1 is number formatted

so the ask is to find duplicate combination of customer, prod and value in the list and in case of match , keep the last item and delete the first item

here, 1 and 4 are duplicate , 3 and 6 are duplicate , but we need to keep 4 and 6 and delete 1 and 3 respectively,
any help will be appreciated
