The modules/datasets most important to us are those which support Budget to Actuals analysis (Journal Entries,  Business Plan/Budget, Cost Center and Organization hierarchy) and those pertaining to the Procure-to-Payment cycle (requisitions, POs, Invoices, Payments, Vendors). 

The ability to monitor revenue and expenses as they pertain to the fiscal budget as the fiscal year progresses.

The ability to measure the duration within the procure-to-pay cycle.

We would hope for a denormalized set of tables which can be queried simply with dimensional context without the need for 'transforming' data and having to resolve dimensional data via multiple joins to the worktags/custom worktags.
