What does the following code means?

overflow ?

catch system-exceptions conversion_errors = 1.

xkomv-kawrt = arbfeld_dec.

endcatch.

When do we use CATCH-ENDCATCH statement?

If a specific statement is expected to error out or throw a exception and you want to handle the error rather than throwing the error / exception to the user, you use the TRY / CATCH block.

You write the statement which is likely to throw the exception in the TRY block and catch the exception in the CATCH block where you specify the action to be taken when the exception is thrown.

In this case you are catching all the system exceptions and when the exception is raised the field xkomv-kawrt is being assigned some value in the variable, arbfeld_dec.

Thanks Ravi..

In my current case, a strange thing is occuring.

The value of arbfeld_dec is 1 but after the assignment xkomv-kawrt = arbfeld_dec, the value of xkomv-kawrt becomes 10 and not 1.

CAn you explain this phenomenon?
