Design of Testing Results of Reduction and Migration of Write Off Transaction Data in POTS Segment Using Integration Testing on SAP Application: Study Case : PT. Telkom Indonesia Tbk

PT Telkom Indonesia is the largest telecommunication provider in Indonesia. There are many transactions carried out to provide services, one of these transactions is Write Off and WS. The number of transactions carried out by Telkom Indonesia and interrelated, Telkom Indonesia requires an Enterprise Resource Planning application, namely SAP, which can help integrate all business processes with each transaction made by Telkom Indonesia. Telkom Indonesia has an increase in customers every year. Most customer increases occur in POTS segmentation, so the data stored on the database server is getting bigger. Larger data can cause performance degradation in the system to load data on the database server and also cause several problems such as the risk of failure when the data backup is getting bigger, the data restoration process is very long so it can affect operational activities. Therefore, data reduction is done on the server and replacing the server to the new device to get more optimal performance. Data on a new device that have been reduced and migrated must be tested against related transactions in SAP to see if the data is consistent. Testing is done using System Integration Testing to make sure data being migrated is consistent.
