What's the difference between class-based exceptions and classic exception?

[Former Member]

Hi buddies,

I was learning the new class-based exception handling, a question suddently jumped in my brain:what's the difference between the new concept and the old exception concept EXCEPTIONS

*\ conversion_error = 1

*\ file_open_error = 2

*\ file_read_error = 3

*\ invalid_type = 4

*\ no_batch = 5

*\ unknown_error = 6

*\ invalid_table_width = 7

*\ gui_refuse_filetransfer = 8

*\ customer_error = 9

*\ OTHERS = 10.

?

In class base exceptions you do not need to capture the return-code at once and after each call, cause sy-subrc might be overriden. Instead you can catch the exception at a central point in the try statement coding the error handling only once.

hi,

Go through this PDF, it will answer all your queries as to why the new class based exception is better.

Classic exceptions are usually mapped to a SY-SUBRC as soon as they occur.

Class based exceptions create an object representing the exception occurred. This object then can have attributes containing further information specifying the exception. (just an example...)
