VAT Tax not being applied to Freight

I am creating a PQuote and adding Freight cost but it has to have Tax added. I have been in to Config Settings “freight_included_in_tax” and set its value to 1. But it is not adding the tax to the PQuote. It is PQuote/PO Worksheet 73.
Any clues please, thanks Denis

Thank you for reaching out about this. I have actually already escalated a ticket for this. It seems this config setting is not working properly. I will send you an update as soon as I have heard back from engineering.

It looks like that config setting only adds the freight to the pretax field. That field only shows up once you convert the PQuote to a PO. This seems to be working correctly. How exactly did you want to add the tax to a PQuote?

I followed what you suggested and converted the PQuote to a PO but the Tax is still incorrect. Tax is only being applied to the line items.
For the UK, freight or postage costs have to have VAT applied. Therefore for for this order VAT has to be applied to the line items and also the freight costs giving a net invoice value of £52.10 and VAT of £10.42, total gross invoice value of £62.52.
I hope this helps, Denis
