after the function modue

CONVERT_TO_LOCAL_CURRENCY

if sy-subrc ne 0.

******write your logic to handle.
else.
******write your logic what it should do if successful.

endif.

whether sy-subrc is 0 or not, if you want to continue with the next statement,then do as follows

CONVERT_TO_LOCAL_CURRENCY

if sy-subrc ne 0.
"no need to code anything
endif.
***you can have your next statements here and there is no need to use continue statement

Hi,

Go in debugging mode and when you reach the FM press F6, after then you will get a value for sy-subrc.

Say if it is 2, the code like:-


CALL FUNCTION 'CONVERT_TO_LOCAL_CURRENCY'.

IF sy-subrc NE 0 AND sy-subrc NE 2.
  MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
  WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
ELSEIF sy-subrc = 2.
  "no code
ENDIF.

Hope this will help you out.

hi ,

You can use CASE sy-subrc statement ...

Check any standard FM and see how error is handled in them

thanks

Hi,

The program will dump only if something incorrect is passed to the parameters of the FM.

In that case there is no way to avoid the dump.

If you want to handle the exceptions then handle them as they are coded when you call the FM via PATTERN in your editor.

hi,

This is very simple, there are two ways to do say.....

1. As this is std FM so when use call this FM there is some code under EXCEPTION just uncomment those code .....your problem will automatically will be solved.

2.If you want to add your own functionality then simply use te case or if-else to check the value of sy-subrc.

As stated by you just write

if sy-subrc ne 0

your code..
endif.

Hope this will help you.

hello,

CALL FUNCTION 'CONVERT_TO_LOCAL_CURRENCY'

EXPORTING

CLIENT = SY-MANDT

date = itab-date_of_export

foreign_amount = dl_kwert

foreign_currency = itab-waers

local_currency = c_usd

IMPORTING

local_amount = itab-value_of_goods

EXCEPTIONS " un-comment these sections

no_rate_found = 1

overflow = 2

no_factors_found = 3

no_spread_found = 4

derived_2_times = 5

OTHERS = 6.

IF sy-subrc NE 0.

MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO " this is display the system message automatically when ever exp are hit

WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.

ENDIF.

here you can use the case statement like:

case sy-subrc.

when 1.

write your code what you want to do if no rate found

when 2.

what do you want to do in case of overflow.

*similarly handle all the cases of exceptons

endcase.

hope it helps
