Validating Numbers

Former Member — Mon, 11 Dec 2006 06:45:16 GMT

Hi,

I have to validate a field for numbers. Its an Amount field. I am taking the input in a Character field and then moving it to an amount field in the code.

I have done the validation for entering characters and throwing error message in this case.

How do i do the validation if something like '1..00' is entered or '1.0.2.3.4.' is entered?

Quick answers will be rewarded.

Thanks,

Rashmi.

Divide the number by 1 and check if it equal to the same number and give a try..

v_var =  v_amount / 1.

if v_var = v_amount.
else.
 *give error message that it is not anumber
endif.

Hi Rashmi,

Here is one idea:

1) Take the number into temp variable l_num.

2) use FIND '.' IN l_num MATCH OFFSET off.

3) then using the offset value in 'off' take the remaining string from there oneards.

4) l_num2 = l_num+off.

5) now apply same FIND on l_num2.

6) if another '.' is found then the input was wrong like 1..0 or 1.2.

Both the condition metioned by u can be validated by this logic.

Hi Rasmi,

you can use CATCH to validate the input...

Please see the following codes:

DATA int TYPE i.

CATCH SYSTEM-EXCEPTIONS conversion_errors = 1.

MOVE 'abc' TO int.

ENDCATCH.

IF sy-subrc = 1.

MESSAGE i398(00) WITH 'Conversion Error'.

ENDIF.

Hi,

I hope the following code will be helpful.

Please do validation in character field only and move to numeric fileds.

DATA:

c_numeric TYPE char69

VALUE '12345 .67890'. " Alphanumc Group

IF lv_amount CO c_numeric.

find '.' in lv_amount MATCH LENGTH mlen.

if mlen gT 1.

Message 'Invalid amount value'.

endif.

--- define your code here.

ELSE.

Message 'Invalid amount value'.

ENDIF.
