DATA number TYPE i.
DATA is_convertible TYPE abap_bool.

TRY.

    number = tested_string.

    is_convertible = abap_true.

  CATCH cx_sy_conversion_no_number.

    is_convertible = abap_false.

ENDTRY.

Why a function module at all?

Read this

https://help.sap.com/doc/abapdocu_latest_index_htm/latest/en-US/index.htm?file=abenconversion_rules.htm

and this

https://help.sap.com/doc/abapdocu_latest_index_htm/latest/en-US/index.htm?file=abaptry.htm

and combine.

Hi Haya,

you can check if the character variable contains only numeric characters values with CO

if l_char co '0123456789'.
   ....

endif.
