Hi,
Something like this, via creating reference and de-referencing it to field-symbol:
DATA if_table_name TYPE string VALUE 'T100' .
DATA it_cond TYPE STANDARD TABLE OF string .
DATA it_from TYPE STANDARD TABLE OF string .
DATA rf_into TYPE REF TO data .
FIELD-SYMBOLS: <fs_into> TYPE any .
CREATE DATA rf_into TYPE (if_table_name) .
ASSIGN rf_into->* TO <fs_into> .
APPEND if_table_name TO it_from .
APPEND 'SPRSL = SY-LANGU AND' TO it_cond .
APPEND 'ARBGB = ''00'' AND' TO it_cond .
APPEND 'MSGNR = ''001''' TO it_cond .
SELECT SINGLE * FROM (it_from) INTO <fs_into>
WHERE (it_cond) .
Also, check outSELECT, Dynamic Token Specificationin ABAP Docu. The type specification for creating data reference can come from RTTI.
I'm sure you'd have found it yourself, had you searched a bit more
cheers
