catch system-exceptions arithmetic_errors = 5. what this statement does

[Former Member]

loop at rt_fieldcat assigning <ls_fieldcat>

where not do_sum is initial

and not no_out eq 'X'

and tabname eq r_tabname

and tech is initial.

catch system-exceptions arithmetic_errors = 5.

assign component <ls_fieldcat>-fieldname

of structure rt_outtab to <sum>.

assign local copy of <sum> to <sumcopy>.

clear <sumcopy>.

in the above code, the statement

"catch system-exceptions arithmetic_errors = 5".

what it is use of this statement

Hi

catch system-exceptions arithmetic_errors = 5.

.................

endcatch.

if the code in the catch and endcatch block raises any arithmetic exceptions then it will make the sy-subrc value as 5 and avoids the dump(run time error)

rgds,

Hi jagan,

You can catch catchable runtime errors in the processing block enclosed between the CATCH and ENDCATCH statements.

syntax :

CATCH SYSTEM-EXCEPTIONS except1 = rc1 ... exceptn = rcn.

rc ... rcn must be numeric literals.

You can include a CATCH ... ENDCATCH block anywhere where an IF ... ENDIF block can be included - that is, local to an event, not cross-event

If a runtime error is caught, the current processing block is interrupted, and the system jumps from the ABAP statement where the error occurred to the appropriate ENDCATCH statement - regardless of how many control structure levels (IF, DO, LOOP, SELECT, CATCH!, etc, ...) must be skipped.

You cannot be certain of the content of the fields affected by a statement where an error occurred, after ENDCATCH.

Example :

DATA I TYPE I.

*CONVERSION_ERRORS contains CONVT_NO_NUMBER *

CATCH SYSTEM-EXCEPTIONS CONVERSION_ERRORS = 1.

MOVE 'abc' TO I. " <- Error: CONVT_NO_NUMBER

ENDCATCH.

IF SY-SUBRC = 1.

...

ENDIF.
