Create data type string with restriction

[Former Member]

Hello,

There is a way to build string with restriction of length ,I know that basically string don't have

any restriction but i need to create data somehow type string with restriction of length like 10 , 20 ,100 etc

when i try to do create data lv_data type ('string') length 8.

i get dump since you cannot limit the string length but there is some workaround ?

Thanks,

Joy

a string with a length is a char(length).

You can try this

DATA weird_string TYPE REF TO DATA.
FIELD-SYMBOLS <fs_string> TYPE STRING.
CREATE DATA weird_string TYPE c LENGTH 8.
ASSIGN weird_string->* TO <fs_string>.
*Now <fs_string> is a limited (8 char) string ... weird !!

Create an object class to emulate a limited length string, in SE24.

Hello,

Why don't you try in this manner

PARAMETERS : p_name TYPE string.
DATA : len TYPE i.
len = strlen( p_name ).
IF len gt 8.
 MESSAGE 'String length exceeds 8 characters' TYPE 'E'.
ELSE.
...
(Your business logic...)
....
ENDIF.

Here in the above example, we are restricting the string length to 8 characters.
