As Simple As SY-ABCDE!

1. In a character string where you want to check whether a string contains any alphabets, try using this one!


    e.g. TRANSLATE lv_var TO UPPERCASE.

           IF lv_test CA sy-abcde.                            "Contains Any A to Z

           .........


SY-ABCDE only checks for CAPITALS A-Z, hence the need to translate the variable to uppercase first.


2. To check whether a char datatype variable contains only numeric characters or not, use this:


    e.g. IF lv_var CN '1234567890.'               "Doesn't contain 0 to 9 and decimal point (.)           .........


You might as well use sy-abcde to check if user has keyed in other than numerics characters, but it is safer to use the latter (1234567890.) because there is possibility that user might key in symbols as well.
