Customer Profile

CLP Holdings includes an electric utility business operated under CLP Power Hong Kong, which is regulated by the Scheme of Control (SoC) agreement with the Government of the Hong Kong Special Administrative Region. CLP Power Hong Kong operates power stations and transmits electricity to 2.2 million customers. CLP Holdings also includes the group’s power-related investments and services in Hong Kong and additional locations.


The CLP Holdings audit team required a more flexible and less time-consuming way to prepare data for audits and to access information from the organisation’s SAP systems.

CLP Holdings auditors download large volumes of data and perform detailed analyses to pinpoint exceptions to business and operating rules. Beginning in 2000, CLP Holdings implemented financial, human resources, work management, and customer relationship management SAP modules. The auditors found that SAP downloads were time consuming, with complex table relationships.

For example, auditors could only download data from one table at a time and were unable to display the table relationships. Additionally, auditors couldn’t save data field selections in the SAP environment and needed to repeat even identical queries for each download exercise. These limitations added time to routine inquiries, especially when there were several hundred data fields in one table and the auditors needed to download data from multiple tables.


The CLP Holdings internal audit department implemented ACL and Direct Link to streamline data downloads and analyses. Auditors now can save data field selections and share scripts and queries for repetitive download tasks. The team can apply ACL’s analytics to find exceptions, anomalies and unusual patterns, and even extract the required data from a report format.

CLP Holdings audit team use DirectLink to extract data from SAP systems faster than the basic download function. With Direct Link, auditors can also join disparate tables and simultaneously download different data sets from various SAP modules – saving time and increasing audit efficiencies.


CLP Holdings relies on ACL Audit Analytics to:

  • Extract large data volumes from SAP systems thereby increasing the efficiency of audits by approximately 60 percent
  • Join tables in SAP and download the results directly to ACL for more efficient analysis
  • Save and share data download scripts and queries for repeated use, improving team productivity
  • Pinpoint anomalies and exceptions in large data tables and extract specific information sets for further analysis
