Hi Sneha,

You could use the "regular expressions" technique for this, but it depends on the version you are on.

Hi Sneha,

When you will execute this code and you will put anything in parameter on selection screen you will get only alphabets.

REPORT z_test.

PARAMETERS: p_text(80) TYPE c DEFAULT 'R~a!m?m@o#h$a%n?4^5&j*A(G)A}N'.

DATA: w_text(80) TYPE c VALUE

'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ'.

DATA: w_len TYPE i,

w_off TYPE i.

w_len = STRLEN( p_text ).

DO w_len TIMES.

w_off = sy-index - 1.

IF w_text CS p_text+w_off(1).

ELSE.

p_text+w_off(1) = space.

ENDIF.

ENDDO.

CONDENSE p_text NO-GAPS.

WRITE : p_text.

Hi,

You can check by sy-abcde and numbers.., if anything other than these is a special character.

if v_text na sy-abcde.

if v_text na '0123456789 '.

message i000 with 'invalid text'.

endif.
