NOTE: This applies to Sage 200 Summer and Winter 2017 Enhancements.
You will get the following message 'Parsing Error : element ‘{http://www.govtalk.gov.uk/CM/envelope} Gateway Timestamp’ has a value which does not match the fixed value defined in the DTD/schema'.

You may still receive an email from the HMRC to say the submission was successful.
To prevent this error we recommend that you apply the hotfix before submitting your online VAT return. You can download and install the hotfix from here.
If you receive the error before applying the hotfix this will not change retrospectively.
This update to the Internet Submissions Component will take precedence over any future versions via updates to Sage 200. To utilise the version supplied in an updated version of Sage 200, this component will need removal via the steps below.
Removal of the component cannot be performed by an un-install. This needs to be performed by a manual change to the GAC.
NOTE: We recommend that the above processes are done with no other users in the system and no local instances of Sage 200 running.
