Try using the addition NO-GAPS (or NO GAPS) in the Concatenate statement.

Reward if it helps.

I think you are mixing a few things up here. The field symbol <fs> is

now pointing at a field (that does not exist), for example WTG001.

I think the statement should be: SELECT SINGLE (lv_fname) FROM COSP INTO

<fs>

(lv_fname) is called a dynamic token and replaced at runtime by the

fieldname .

Actually, I also think the field-symbol assignment doesn't work either.

Just check the sy-subrc after the assign statement! You also need the

COSP- part of the name.

Have a look at this example:

DATA: wa_t001

TYPE t001.

DATA: tp_fieldlist TYPE string VALUE 'BUKRS'.

DATA: tp_fieldname TYPE string VALUE 'WA_T001-BUKRS'.

FIELD-SYMBOLS: <fs> TYPE ANY.

ASSIGN (tp_fieldname) TO <fs>.

IF <fs> IS ASSIGNED.

SELECT SINGLE (tp_fieldlist) FROM t001 INTO <fs>.

WRITE <fs>.

ENDIF.

Just check help on SELECT statement.
