or

Inherit the report.  sale.report_saleorder and add your own changes there. Add the new fields in the report too.

Thanks

Hi Nikhil,

Thanks for your help.

I think I may have been confused in my initial question. I am not looking to update a custom field on Sales Order or the PDF Print version.

Rather, I am looking to update fields in the Sales Analysis Report. There are certain fields at the moment and I'd like to add extra fields to analysis them.

Sorry if that was a bit of a confusion.
