Check out below code. It will help you.

data: str(100) type c.

data: str_n type string.

data: str_c type string.

data: str_d type string.

data: str_p type string.

data: len1 type i.

data: ofst1 type i.

str = '#ABCD%123'.

len1 = strlen( str ).

do.

if ofst1 = len1.

exit.

endif.

if str+ofst1(1) co sy-abcde .

concatenate str_c str+ofst1(1) into str_c.

elseif str+ofst1(1) co '0123456789' .

concatenate str_p str+ofst1(1) into str_p.

else.

concatenate str_d str+ofst1(1) into str_d.

endif.

ofst1 = ofst1 + 1.

enddo.

data p_field type p decimals 2.

CATCH SYSTEM-EXCEPTIONS conversion_errors = 1. 
MOVE str to p_field.

If lstr CA Sy-abcde.

-> dont do any calculation.

else.

-> do your calculation.

endif.

Alternatively you can use FM: CATS_NUMERIC_INPUT_CHECK for the same or even: NUMERIC_CHECK

Hi,

One simple way is this.

If var CO `0123456789`.

this contains only numerics

else.

endif.
