In accounting, a "journal" is a chronological record of financial transactions.

The phrase “consolidation, journals, business-critical reporting, and analysis.” is in the actual report referring to multiple spreadsheets (p60). But the Register has reported that as referring to the main spreadsheet. There's no way a top-level consolidated spreadsheet would also be journal entries for low level accounting.
And I note the report is by Deloitte who I trust about as far as I can throw them, although the organisation in question undoubtedly messed up here, Deloitte are angling for a nice juicy government ERP implenmentation lasting years and costing tens of millions
