Hello!

Obviously many concepts of OpenERP will fail if the amount of data becomes large (some million records)
for this we will mateialized views (typically account_move_lines, stock_moves, SO/PO lines, timesheet lines etc)

another way to go could be to integrate OLAP concepts like
http://packages.python.org/cubes/ (have not analyzed details)
which are made exactly for analysis of data

Title:
  SQL query in invoice analysis is too complex

Status in OpenERP Addons (modules):
  New

Bug description:
  On our modest database containing (66000 invoice lines, 1200 products,
  3 partners), the Invoice Analysis takes so long to execute that the
  client times out.

  As it turns out,  "explain select * from account_invoice_report"
  estimates the cost to 1009607118.61, which is really huge.

  I tried to backport the latest report from the trunk, which is a bit
  better but still far to costly to be usable. explain estimates the
  cost to 734148039.28 - an order faster than v6, but still far from
  usable.

  This query has far to many refinements in my opinion, and it should be
  drastically simplified by dropping or optimizing costly computations.
  Features like currency rate conversion, delay to pay, residual amount
  seem to be complex beyond reason - but a finer analysis is needed to
  confirm this.
