The principle business activities are picked up from the SIC codes entered into Client | View | Categories or from the option to 'Override SIC Codes' located against the Annual Return Date History Event (Client | View | History | View)  

The UK SIC codes database has been updated to use UK SIC 2007 codes which are applicable to Annual Returns made up on or after 1st October 2011. For returns made up before 1st October 2011 where UK SIC 2003 codes had previously been selected, these will continue to be used until a return made up on or after 1st October 2011 is generated, at which point the SIC code entered under Client | View | Categories will need to be updated.  

Where a discrepancy occurs with the SIC codes selected or a UK SIC 2003 code is required (for a return made up before 1st October 2011) an 'Override SIC Codes' option is available under the Annual Return Date History Event.

If no SIC codes have been entered, then the trade classification codes area will be left blank. There is a space underneath to manually enter a Principle activity description if required.
