Prior to Integrated Enterprise Resource Planning (ERP) systems, accounting programs have been referred to as transaction processing systems. For these systems, the only concern was tracking financial data and accounting transactions. Companies using such systems had to come up with methods of recording and storing other data relevant to business activities, such as fixed assets, inventory, and billing (customer accounts). The use of these subsystems within a transaction processing system resulted in major problems and inefficiencies.

Which of the following issues was the LEAST concerning for managers from an internal control perspective?

		Efficiency - Duplication of effort in the different subsystems meant less work overall could be done.
		Redundancy - When creating new records, the same data had to be captured and stored by more than one system or subsystem, meaning a higher likelihood of inconsistent data.
		Update Discrepancies - Updates to existing data needed to occur in multiple places, resulting in a high likelihood of discrepancies between subsystems.
		Integration Failures - Some companies integrated subsystems using automatic exports/imports, but these were subject to failures from inconsistent data and improperly mapped imports.
