Could you please let me know if this problem has been resolved and how? 

I, too, have to post a purchase invoice for services from Ireland with VAT Reverse Charge applied and I cannot find the correct VAT code in Desktop Pro so that Boxes 1, 4, 6 and 7of my VAT return are populated as required by HMRC in Notice 700/12 , para 4.6.  This is even more important now MTD has arrived.  I phoned customer support and spoke to someone in the Philippines who couldn't get their head round the problem.  They told me to use the RC code, but using this code only populates Boxes 4 and 7 (two entries in Box 4, one +£20, one -£20 vat, resulting in a nil effect).

Please could someone tell me how to resolve this?  Thanks.
