using sy-subrc you can handle the exceptions.

using try catch blocks also you can handle the exceptions.

Hi Arun

Error handling is different from excepion handling. An exception is a situation during ABAP program execution in which normal program continuation does not appear to be desirable. Exceptions can be triggered both implicitly and explicitly in the ABAP program.

Here are few useful urls.

I hope this will help. Dont forget to give points, if its worth :).

Hi,

There are different causes for ABAP errors, depending on the program.

<b>Causes include:</b>

1. Incorrect or incomplete entries in the RFC destination (transaction SM59)

2. Network problems

3. Authorization problems

4. Error in the RFC program

<b>Error Handling:</b>

Classical ABAP exceptions are raised by <b>RAISED</b> and can be handled by calling methods and function modules using the <b>EXCEPTIONS</b> clause. These exceptions cannot be handled when calling subroutines, instead they are propagated automatically to the next non-subourtinate level.

Some of the exceptions can be caught if the statement that caused the runtime error is placed in a <b>CATCH SYSTEM - EXCEPTIONS</b> block.

<b>MESSAGE</b> statements can also be used to indicate errors.

For Type E or A : can be cought directly by calling methods and function modules using the EXCEPTIONS clause and exception name <b>error_message</b>
