Function module to validate numeric values

[Former Member]

Hi all.

Can some one please tell me Is there any Function Module to validate only numeric values?

Like in year variable, it can never contain alphanumeric values or special symbols?

Is there any function module to check, wheather the variable contains only numeric values, no alphanumeric value or special symbol?

If there is no as such function module then what is the alternative approach we can take?

Plz help me .

Function Module NUMERIC_CHECK for Editing and checking numeric fields ( i.e. Num validations)

Check using the Function Module "NUMERIC_CHECK".

CALL FUNCTION 'NUMERIC_CHECK'

EXPORTING

STRING_IN = X

IMPORTING

STRING_OUT = X

HTYPE = H_TYPE.

if h_type = 'CHAR'.

WRITE:/ 'Not Numeric'.

else.

write:/ 'Numeric'.

ENDIF.
