Can some one help us with the differences between change impact analyser in SAP TAO and change impact testing in
HP quality center.
Please share some process documents regarding the same.
The Business Process Change Analyser in Solution Manager compares a technical BOM (TBOM) that is maintained within a solution, or project, against a transport order that is maintained within a managed system. The TBOM is a listing of all technical objects, for example tables, programs etc, that are used by the managed system. BPCA checks the contents of the transport order against the TBOM. BPCA then highlights the objects in the TBOM that will be impacted when you import the transport order into production. From the BPCA you can directly create a Test Plan and select the test cases that will test the objects that will change.
SAP TAO inspects transactions to determine the technical information required to generate an automated test. TAO then creates scripting for HP Quick Test Pro test cases and can create business components in HP Quality Center that can be used to compose business process tests.
HP Change Impact Testing allows you to import changes from the SAP correction and transport system, analyse and identify the impact of changes, assess their risk and recommend which business processes to test.
There are some good presentations about BPCA and TAO and this one could give you the back ground info to the SAP solution: https://websmp104.sap-ag.de/~sapidb/011000358700000988132011E
Hope this helps,
I'm not sure about the impact testing but the BPCA analyzes all the changes performed when you jump into a satellite system and perform any kind of action. It can collect a log of each action performed when in the satellite system, or just a change in the states.
So it can be used basically as a control of the changes performed by the users in a project at every step in which they access the satellite system.
Kind regards, Fabricius
