Archive for the ‘UI’ Category
Sometimes when I try to login to the SAP system, the GUI pop up the error message “Error: Service ‘?’ unknown”. I confused by this error message but don’t know how to fix this.
I got some time today and fortunately found the route of the problem.
Transaction Code: VFBS.
Function Module: SCREEN_SEQUENCE_CONTROL
Function: SCREEN_SEQUENCE_CONTROL
Function group: V00F
Summary
Determination of the next screen from the function code
If you develop the custom screen, you always need to deal with the search help. Some search help comes from the DDIC definition. In some case the search help value comes from program dynamically. Below code example shows how you can populate search help.
In the screen flow logic:
In the ABAP dynpro programming, we always deals with OK_CODE which contains the function code user triggers. For each screen, there is a default UI element with type OK. The element is used to pass function code to the program for further processing.
The PAI event of screen is triggered by choosing an button in the GUI status or press certain key. The corresponding function code is placed in the system field SY-UCOMM and placed in the OK_CODE field as long as the function code is not empty.
The GUI status consists of a menu bar, a standard toolbar, an application toolbar, and a function key setting. When you define a dialog status in the Menu Painter, every function code is assigned to a menu entry in a menu bar and/or to a freely-assignable function key on the keyboard.
There are many web applications delivered by SAP for solution manager. These applications can be easily integrated into the Enterprise portal and provide web base access for all the business users. I summaries these applications into below three categories according the technologies it uses.
ITS based web applications
The ITS (Internet Transaction Server) is the essential link between SAP systems and the Internet. It is the first generation web technologies of SAP.ITS translate the dialog protocol of SAPGUI and translate it into the internet protocol like HTTP.
Introduction
SAP WebGUI has another name called ‘SAP GUI for HTML’. This UI technology is based on integrated ITS and present all the data in the browser.
The SAP WebGUI generates HTML pages for every SAP screen. This means you do not have to create any templates. There are some technical restrictions due to the browser, however, and certain transactions may not function in the SAP GUI for HTML. This must be decided for each case. The use of controls can result in this restriction.
With patchlevel 11 SAP GUI for Windows SAP GUI for Windows 7.10 fully supports the new “SAP Signature Design” (this is also available as part of the 7.10 Compilation 3 DVD). The screenshot below gives you an impression how the new design looks like:
