To begin, we must keep in mind every SAP implementation is different. That is because every business is different in the details related to their individual business processes and/or master data. Even with in the same company or entity, there can be slight or major differences in a business process or master data based on an enterprise slice. Some parts of the organization perform business one way, while another performs business another. While this is a challenge during implementations, SAP has delivered many different enhancement options. These may be leveraged by the design and development teams to meet the needs of the organization. Enhancement options are always preferable to core modifications when possible.

A large enterprise’s networked computing environment is likely to connect many geographically distributed computers to the main database. These computers are likely to use different hardware and/or operating system platforms. An IDoc (for intermediate document) encapsulates data so that it can be exchanged between different systems without conversion from one format to another. IDocs are used for for electronic data interchange (EDI) between application programs written for the popular SAP business system or between an SAP application and an external program. IDocs serve as the vehicle for data transfer in SAP’s Application Link Enabling (ALE) system.
The ALV Grid Control solves this problem. Its user interface provides a set of generic functions (e.g., sorting, filtering) for handling tabular data. 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. How you “plug” the control into an application is the first thing I will show you in this month’s blog. So lets get started!
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.
Let’s review some of the technical aspects of controls technology:
-The SAP Control Framework
-The Automation Queue, and the issues surrounding “flushing” it
-Event handling
-Error handling
Including Controls Technology controls on the front-end establishes a client/server relationship between the application server and the controls on the presentation server.
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.
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!
SAP NetWeaver 7.0 (formerly 2004s) offers the new Enhancement Framework that not only is intended to unify the modification and classic enhancement techniques, but also offers you almost the same flexibility as modifications without the limitations of modifications.
