ABAP Dump Analysis 
If an unhandled exception occurs while an ABAP program is executed the ABAP runtime environment triggers an ABAP runtime error. The execution of the program is terminated and a detailed error log (short dump) is created and saved in the affected ABAP system.
You can access the saved short dump in the following ways:
In a runtime error occurs in a dialog process, the system immediately displays a screen with the short dump. For further checks you can then branch directly to the ABAP Debugger. For more information, see Displaying a Short Dump Directly
Using tools of the ABAP Dump Analysis (ST22) you can display information about the runtime error that occurred again and investigate the short dump, save it locally, or print it.
You can access the internal Administration of the short dump that has been saved. For example, you can avoid the short dump being deleted automatically.
