How can I add a field to a report to be used in Report Rules?

I am trying to create a Report Rule for ORDER_QUOTATION_REP but the field I want to use is not available. MARKET_CODE is available on the SALES QUOTATIONS screen but not in the ORDER_QUOTATION_REP view. How can I add this field? Should I use IFS Developer Studio? Are there other ways to add fields?

Thanks,
