Benefits of QA platform for SAP NetWeaver BW Accelerator
Customers who are productive with SAP NetWeaver BW Accelerator understand the value proposition it brings to their whole SAP NetWeaver BW landscape like performance, reduced TCO, consistent response times etc. In order to completely realize and tap all the benefits of SAP NetWeaver BW Accelerator, it is equally important to clearly comprehend the need for a quality assurance system (QA) for SAP NetWeaver BW Accelerator. In this blog, we will focus on the value proposition of QA system for SAP NetWeaver BW Accelerator and get answers of some questions like why it is so important to have a QA system for SAP NetWeaver BW Accelerator.
One of the important reasons to have QA system for SAP NetWeaver BW Accelerator is to ensure functional correctness. It means all the reports which are based out of indexed data in SAP NetWeaver BW Accelerator should functionally display correct results in QA environment to make sure that the end users of the productive environment are not furnished with wrong information. If for some reasons the output of QA environment is not correct, it would still be possible to correct the data marts or the reports before it is transported to the production environment for live usage. As the intention behind business intelligence reports is to facilitate key decision making by providing realistic picture of the business it is of paramount importance to bring forth the functionally correct results to the decision makers.
In addition to ensuring the factually correct results, it is equally important to display the results in fast and consistent manner to the end user of the productive environment. To ensure a consistency in behavior and data the QA system for SAP NetWeaver BW Accelerator helps in checking it beforehand so that the expectations of the end user of the productive environment are fulfilled in terms of performance, consistency and correctness of the data. A typical issue which could arise if a customer does not have a QA platform for SAP NetWeaver BW Accelerator is that they might lose out on the one of the key benefits which is reduction in change-run and roll-up times. This lesser-known capability can help customers reap additional benefit and ROI from their SAP NetWeaver BW Accelerator implementation.
Consider the following SAP NetWeaver BW scenario where no SAP NetWeaver BW Accelerator is available in the QA landscape: To ensure that queries in SAP NetWeaver BW QA system are performing reasonably well, the customer might choose to create aggregates in the QA system which needs to go through the standard SAP transport mechanism thus leading to some quantity of redundant data in the production system as well. As SAP NetWeaver BW Accelerator is attached to the production system and also there are aggregates existing in the production system, now if there are any change-runs or roll-ups are scheduled for any kind of change in the master data, this will lead to a considerable loss of time because aggregates need to be updated separately.
SAP NetWeaver BW Accelerator provides all software updates Revisions. As a best practice, customers tend to avoid any changes to a Productive landscape without some assurance of the impact of the updated functionality in their environment. In addition to mitigating risk through a robust change management process, customers can test OS patching and associated new releases beforehand instead of doing this in the productive SAP NetWeaver BW Accelerator installation. Moreover, SAP NetWeaver BW Accelerator provides significant additional value when it comes to the integration test of newly developed BW applications — particularly if the applications were written with SAP NetWeaver BW Accelerator in mind and without which the performance would not be acceptable. Adhering to the time-tested practice of having a QA system will help to ensure uninterrupted service and higher end user satisfaction in the productive environment.
Future direction of SAP NetWeaver BW Accelertor:
The evolution of SAP NetWeaver BW Accelerator from an engine to gradually more like an application on top of the engine strongly suggests that QA system is a must to test the scenarios before making it live in a productive environment. The roadmap of SAP NetWeaver BW Accelerator suggests that the new scenarios like ‘SAP BusinessObjects Explorer, accelerated version for SAP NetWeaver BW’ are benefiting from innovations like built-in analytical capabilities (calculation engine, aggregation engine) and a modeling environment, which provides more flexibility. At the same time there is an increasing need for these applications to be tested extensively before using these scenarios in a productive environment.
As an additional benefit, it is also possible that a QA system for SAP NetWeaver BW Accelerator can be attached to more than one SAP BW system unlike a production environment for SAP NetWeaver BW Accelerator which can legally be attached to only one SAP BW system. So customers could flexibly have QA system for SAP NetWeaver BW Accelerator and attach it to a Sandbox, Dev and QA systems of SAP BW.
It is imperative to realize that the technologies employed by SAP NetWeaver BW Accelerator are vastly different than the core SAP NetWeaver BW environment and related aggregate capabilities. As the QA landscape is needed for critical tasks like final migration tests, evaluating data quality and consistency, it is crucial to use the same code and database in the quality landscape as in the production landscape. Ultimately to ensure data consistency as well as consistency of behavior, a QA environment for SAP NetWeaver BW Accelerator is a must with every productive SAP NetWeaver BW Accelerator customer.
In terms of pricing, customers of SAP already realize that there is no additional licensing cost for the blades used in the QA environment for SAP NetWeaver BW Accelerator. This eventually makes the QA system for SAP NetWeaver BW Accelerator lot cheaper as customers have to just pay for the cost of the hardware and not the software licenses.
