Caution is the key word! You can individually activate a business function using the switch. They represent the smallest switchable unit; that is, they can be activated as a unit. The authors describe all relevant project phases and present the most critical activities based on real-life examples. Enhancement packages are cumulative, so when component Y is upgraded with enhancement package 3, component X is also upgraded to the same version. Enhancement Package Projects Discover how to optimally approach the implementation of enhancement packages.
Best regards, Jill Hi Jill, it is not recommended to transport between systems which have different software component versions e. Documentation and Release Information If you need more information about a business function, choose the Documentation and Release Information icons. As a result, software update processes no longer refer to single systems, but instead to complete landscapes. By the way: Your feedback about our documentation is most welcome — just drop me a mail. Therefore, there is no impact on the regular business processes. Technical usages The business functions require software components that must be installed together. We have added the latest innovations delivered with Support Package 10, released in April 2018.
This targeted update and activation process is key within the delivery methodology of enhancement packages. Comprehensive Technical Description Get answers to all your questions about the architecture of enhancement packages and the use of the Switch Framework, from development basics to technical details. Stack configuration file The stack configuration file is created by the Maintenance Optimizer and is system-specific. I hope I also shed light on the equivalence level. Practical Application Take advantage of best practices, checklists, and tips and tricks from the authors, all of which make this book a useful companion you can consult time and again. It is not possible to deactivate a business function. In addition, you can leverage synergies concerning modification adjustment as well as regression testing for all software components at that time.
Note that enhancement package releases are denoted as 602 for EhP2 , 603 for EhP3 , and so on. Installing an enhancement package requires a regression test the same as the test required when implementing support packages. Switch framework: Change Business Function Status screen Name and Description Each row contains name and a description of the business function. Table An overview of important terms used in this article Dr. Furthermore learn how and where you can find the related information. A guided procedure leads you through the preparation process for updating your systems.
Landscape patterns Landscape patterns describe how systems are used in a landscape. Now you are able to describe the overall implementation sequence as well as the technical details of the installation process. An enhancement package delivers several business functions. For example, if the business function requires the activation of any other business functions, they would be listed here. Please make sure you map the Business Function to the corresponding Technical Usage. If you are not sure if you want to leverage dedicated functionality, use a Sandbox System to explore the new functionality.
Landscape-Aware Enhancement Package Implementation Scenarios The motivation to adopt new innovation within your system landscape through enhancement packages can be application-driven or technology-driven. The changes are documented in the corresponding documentation for each business function. First, I will provide an overview of the lifecycle management process for planning and implementing enhancement packages. If you want further information please have a look at the we provide: E. This is independent of any switch activation.
The maintenance project for an enhancement package installation is done on the product system level. This could lead to interdependencies of the technical systems during system maintenance and enhancement package implementation. As previous columns have discussed, enhancement packages provide collections of new or improved business functions that you can deploy modularly and on your own timetable; you can tailor your upgrade strategy based on the functionality you need. Activating a business function triggers switches, which then enables the execution of the code enhancements. The differentiating feature is a new switch framework that controls the activation. As we allow now mixed software component versions within one logical system it is important to understand their relationship. For a brief description of the System Landscape Directory and other key terms used in this article, see the table at the end of this article.
The Solution Manager Maintenance Optimizer automatically calculates all needed Support Packages and new software component versions needed for installing the previously selected Technical Usages. You will work with experts from other functional applications and the Netweaver team to compile a list of all the business functions and the corresponding technical usages that are required for your organization. From here on, you will follow the regular change management process to configure changes, test, document, and transport to the production environment. It helps guide you in the implementation process. The following terms are important to understand: Business functions The new innovations are grouped together into small bundles called business functions. The process of implementing a new business function can be broken down into four steps: identification, installation, activation, and configuration.
