Answer 1

Hi Sayeda,
1). Open any Standard Webdynpro Component to enhance.
2) If you want to Enhance a method or design a layout on the View, then select the View and then select the View -> Enhance from the menu bar.
3) Give the Enhancement Name and Description and save it.
4) After saving you can see that the view would be in inactive state and in the status bar you can see a message like u201CEnhancement implementation XXXXXXXXXX createdu201D. (Where XXXXXXXXXX is the name you had given earlier)
If you navigate to method tab, you can see Pre-Exit, Post-Exit, & Overwrite Exit.
a)Pre-Exit u2013 If you write code in this method, it will execute before the standard method executes.
b)Post-Exit u2013 If you write code in this method, it will execute after the standard method executes.
c) Overwrite Exit u2013 If you write code in this method, the standard method will be overwritten by this method and only the overwrite exits will work.
6) Just click on the create button on anyone of the method based on requirement and write your code and activate it and execute the application.
