A single Business Add-In contains all of the interfaces necessary to implement a specific task. What is difference between badi and user-exists? What is difference between enhancements and user-exists? What is the system landscape? Used for finding error records. The best part of these enhancements is that they behave like the actual code and at the same time, they are transported separately among the different landscapes.
Earlier, we have seen that we were able to add code into the source code and transfer the same to different landscapes. SAP later created a new type of enhancement framework which uses Object Oriented concepts. This new Enhancement technique, thus, was created in form of class and objects and was available for reuse.
They are object oriented based enhancement techniques that can be reused. SAP NetWeaver 7. In contrast to enhancements in the Enhancement Framework, modifications are physically part of the object they modify. This means that every single modification gets lost in an upgrade and needs to be re-inserted even in cases where the underlying SAP object has not changed at all! In all the aspects, enhancements are more powerful than modifications, even given all the modification support that transaction SPAU offers.
The reason is due to an important difference between an enhancement and a modification that stems from the conceptual difference between the two technologies. No matter if you create an enhancement point or a BAdI as an enhancement option provider, or if you implement an existing enhancement option be it implicit or explicit , what you create must fit into the structure of the Enhancement Framework in a way that enables you to collect and organize the enhancement options and their counterparts on the implementation side.
The Controls Technology Framework resides on the application server the back-end , and the Automation Controller sits on the presentation server the front-end. The integral component that optimizes the communication between the two is the Automation Queue.
I will continue to take a look at the SAP Controls Technology and how we can use it in our development. I will focus on Events and their respective handling techniques along with errors. Its user interface provides a set of generic functions e. It also confers the many benefits of controls technology to users, enabling more operations by mouse, and interaction with other controls, such as drag-and-drop.
Developers simply plug the ALV Grid Control into their applications and the tool takes care of the rest. You do not need to do any further programming to offer users these functions.
So lets get started! There is an event for each element type toolbar push button, toolbar menu, and context menu. In the relevant event handler method, you define the properties of an element such as its menu options and assign a function code to each executable function.
What is web Dynpro? Web Dynpro was created because, like every other software vendor in the Web space, SAP needed a longterm, strategic solution for the many problems faced by Web developers during the implementation of browser-based business applications.
One of the best things about building Web Dynpro applications is that their architecture is defined declaratively, rather than programmatically. This means that you use graphical tools to build units of the application — for example, screen layout, the navigation paths from one screen to another, and the data structures used to hold the business data — and then the Web Dynpro development environment ties them together to create the final application.
