Just looking over the linked KIIDs/KIDs for your ETC/ETF range and wanted to highlight a few things:
Some links don’t work.
For example IE00BP3QZB59
Some link to the wrong document.
For example IE00B53HP851 links to document:
Which is the KIID for IE0005042456 which is a close relation of IE00B53HP851 but not quite accurate. Not the highest crime I do realise!
Some (actually quite a lot!) are out of date
For example IE00B3Q19T94
You link to a document dated 25/05/2018
Via the magic of the finki KIIDs API (plug plug!) I can tell you the latest document for the product was released 18/02/2019
