raise error message in loop and exit

Former Member — Wed, 25 Jun 2008 08:22:06 GMT

Dear Friends,

I am looping on an internal table and validating data.

so if in between if i find any inconsistency, i want to throw an error and exit.

let me put it in sample code.

loop at itab1 into wa1.

perform check_data using wa1.

endloop.

form check_data using wa1.

if wa1-field1 is initial.

message 'No Data can't save' type 'E'.

i want to give this error and end loop processing

how can i give?
i can't use continue also as its not in loop endloop.
friends pls suggest.

endif.

endform.

Regards,

Simha

Hi Simha,

Hope following code can give you idea:

loop at itab1 into wa1.

perform check_data using wa1 changing lv_error.

if lv_error = 'X'.

message 'No Data can't save' type 'E'.

exit.

endif.

endloop.

form check_data using wa1 changing p_error.

if wa1-field1 is initial.

p_error = 'X'.

endif.

endform.

Thanks,

Victor.

Hi Simha,

do like this.

DATA: w_message TYPE c.

loop at itab1 into wa1.

perform check_data using wa1 CHANGING w_message.

CHECK w_message EQ 'X'.

EXIT.

endloop.

form check_data using wa1 CHANGING p_message.

Do ur validations

CHECK wa1-field1 is initial.

message 'No Data can't save' type 'E'.

MOVE 'X' TO p_message.

endform.

Another way could be issue message directly in the loop instead of doing in form and then exit.

DATA: w_message TYPE c.

loop at itab1 into wa1.

perform check_data using wa1.

CHECK wa1-field1 is initial.

message 'No Data can't save' type 'E'.

EXIT.

endloop.

form check_data using wa1.

Do ur validations

endform.

Thanks,

Vinod.

Hi,

try the following :

data:

begin of wa1,

field1 type i,

end of wa1.

data:

itab1 like standard table of wa1.

start-of-selection.

write logic for fetching the data into itab1.

loop at itab1 into wa1.

perform check_data using wa1-field1.

endloop.

form check_data using wa1-field1.

if wa1-field1 is initial.

w_flag = 'X'.

stop.

endif.

end-of-selection.

if w_flag = 'X'.

message 'No Data can't save' type 'E'.

endif.

Hi friends,

Thanks for your suggestions.

I now understand that i can't raise a Error message in form endform and only way is to pass back a flag indicating that there is an error.

I got it.

Thanks for your help.

Simha
