Few days back, I was developing an application where I had to reproduce some functionality of “Pattern”. I had to display a screen which took the name of the function module which the developer is intending to call in her program, And then include that function module at right place in the report. Since this thing already exists, I thought to run the “Pattern” screen in debugging mode and see how the developers have done it before. But alas! I was unable to run it in debugging mode using conventional way of doing it. Someone* helped me with this. Following are the steps to do it: 1. Go to Customizing of local layout->Create Shortcut as shown below. 2. Set the type to “System Command” and Command to “/h” as shown below and then click Next: 3. Set the working directory to your desktop and click on Finish. A message window will pop up saying that the shortcut was successfully saved. But nevertheless check your desktop for the new icon. Now we are ready for the game. Click on pattern button. Fill in the entries which you want. Now drag that icon which we just made onto this pattern screen and then click on green check button. Bingo!! I am in debugging mode now. *Thanks Debasish for helping me.
