Hi,

Could any post solution for given below requirement.

I have to design validation logic for a selection-screen where I need to input only Numeric values for a field so that it should give an error message if I enter Non-Numeric values.

Thanks,

G sandeep.

Hi,

Please Test the following Sample Code.

PARAMETERS: pstring TYPE string.

AT SELECTION-SCREEN.

  IF pstring CA '1234567890'.

    MESSAGE 'You enter Nomaric' TYPE 'I'.

  ENDIF.

Test following Too for Non Nomaric

PARAMETERS: pstring TYPE string.

AT SELECTION-SCREEN.

  IF pstring CN '1234567890'.

    MESSAGE 'You enter NON Nomaric' TYPE 'I'.

  ENDIF.

Hope will solve out your problem,

Kind Regards,

Hi Sandeep,

You can achieve that by either:

1. create a select-option which refer to integer data type. By default SAP will do automatic checking of the input against the data type, or

2. Create your own validation using event AT SELECTION SCREEN ON <select-option>.

LOOP at <select-option>.

IF NOT <select-option>-low CO '1234567890'.

throw the message

ENDIF.

IF NOT <select-option>-high CO '1234567890'.

throw the message

ENDIF.

ENDLOOP.

Lim...

Hi,

Define the parameter type as 'N', So when you are entering non numaric value in that selection screen it doesnt allow you

PARAMETER p_numc TYPE string.

AT SELECTION-SCREEN.

DATA: lw_out TYPE string,

lw_htype TYPE dd01v-datatype.

CALL FUNCTION 'NUMERIC_CHECK'

EXPORTING

string_in = p_numc

IMPORTING

string_out = lw_out

htype = lw_htype.

CHECK lw_htype <> 'NUMC'.

ERROR MESSAGE

hi,

Declare the parameter as N i.e numeric.

This will not allow ant non- numeric values.

Hi,

U can use the FM 'NUMERIC_CHECK'.

The import parameter is STRING_IN. If u are entering numeric values, like 0 to 9..it will display the output parameter STRING_OUT as inputed number padded with zeros and HTYPE as NUMC, which means the value entered is numeric.

If u enter any non numeric value, this will output the HTYPE value as CHAR.
