The Australian Taxation Office (ATO) is supplementing its existing SAP R/3 modules with the new Business Information Warehouse (BW) application.
It went live with SAP's Financials and Treasury modules 12 months ago; all ATO offices across the country went online with the General Ledger.
The ATO's director of personnel systems, Paul Wight-Wick said the BW module was scheduled to go live along with the Human Resources unit in the new financial year.
The ATO's existing IT system provides HR and employee self-service (ESS) functions, but its lack of integration with enterprise financial systems meant that staff were building and continually maintaining software 'bridges' and data reconciliation processes, Wight-Wick said.
The SAP modules would replace that legacy system which had limited access, he said. The additional SAP modules would allow the ATO to reduce the cost of maintaining those business processes.
About 18,000 staff members at the ATO already use ESS-type systems for functions such as maintaining contact and address details, submitting applications for leave, overtime and higher duties and the receipt of pay slips, he said.
"Currently we're in a position of maintaining several systems, which detracts from our ability to concentrate on higher value-adding tasks," he said.
The BW will be used at the back end of the HR module, Wight-Wick said. He said the warehouse would be automatically populated with data from the other SAP modules.
