Symptoms:

Cause:

HMRC updated their servers with RIM Artefacts and Taxonomy changes which were deployed into the Live service on 11 December 2017.

Along with these RIM Artefacts and Taxonomy changes, HMRC also removed some DPL taxonomy that was used for computations for earlier periods. In effect from 11 December 2017, HMRC have stopped accepting the 2013 DPL for Accounting Periods starting after 31/12/2015 and there is no backward compatibility. Any submissions made for APs starting after 31/12/2015 using older version taxonomy will be rejected by HMRC.

Solution:

1. Where you have attached Accounts and Computations iXBRL files generated through a third party Final Accounts Production software, please contact your software provider to update or upgrade their software.
   

   Once you have upgraded your Final Accounts Production software, generate the iXBRL documents again, and attach the newly generated iXBRL files into Andica CT600 software.
   

   If your Accounts and Computations were tagged by a tagging service provider, you will need to get them to tag these correctly.
   

2. Where you are using the free basic inbuilt Accounts and Computations template within the CT600 software Version 2017, follow this advice:
