Function module to validate input value

Former Member — Wed, 19 Sep 2007 13:03:49 GMT

Hi all,

can you please provide me the name of the function module to validate input value.

I have a case where i have to validate decimal values. sometimes users may enter wrong decimal values by mistake instead of "0.23" "0..23' and it gives CONVT_NO_NUMBER runtime error so have to come up with some solutions to validate user input.

Please provide me Function module if anybody knows.

Thanks,

Try this one


data: lv_htype TYPE dd01v-datatype.

    CALL FUNCTION 'NUMERIC_CHECK'
      EXPORTING
        string_in = my_number
      IMPORTING
        htype     = lv_htype.

    IF lv_htype NE 'NUMC'.
       Raise an error here...
    ENDIF.

Hi,

Thanks for the reply but how about decimal values. i have to check on decimal values like if user inputs 0..23 instead of 0.23 it should not raise an system error. with 0.23 also it gives as CHAR.

Thanks,

The standard format checks are taken care by the SAP system itself one need not to validate them.

Ex:

parameters:

p_pack type p decimals 3.

Now, if u try to execute the program with incorrect data ( Ex :0..234 or 0.2345 ) the system itself throws an error message

Hi,

While declaring the numeric fields use the below code, this validation will be taken care by SAP itself ;

parameter : dmbtr like bsis-dmbtr.

Thanks,

Use FM CATS_NUMERIC_INPUT_CHECK

If you maintaining different floating point, assign INTERNAL as 'X'.

Hi,

Use try and catch for handling the exceptions and show exception message to user.

exception class : - CX_SY_CONVERSION_NO_NUMBER

Hi,

Use Split statement on decimal '.' .

if value are going into three variables then it's wrong input.

Example.

V1 = '0.23'

Split V1 into V2 V3 V4 .

if V4 IS INITIAL .

"CORRECT ".

ELSE.

"WRONG "

ENDIF.

Check for V1 = '0..24'

value will come in V4 variable .
