There was a bug which meant that Transfer Request Responses were not getting removed confusing the staff into resubmitting them. The fix is simply to change the status to '2'
Example tickets:
https://advancedretail.freshdesk.com/a/tickets/136963
select whse_no, * from vw_branchwarehouse where branch_name like '%?%' select * from transfer_request_response_hdr where sending_whse_no = ? and status = 1 update transfer_request_response_hdr set status = 2 where guid in ('?')
