Error: dynamic SELECT command in abap Opensql

Question

Hi!
When I try to run this program, the session terminates, the work process restarts:
DATA:
  string1 TYPE STRING,
  string2 TYPE STRING,
  string3 TYPE STRING,
  lt_trkorr TYPE TABLE OF E070-TRKORR.
string1 = 'TRKORR'.
string2 = 'E070'.
string3 = 'TRKORR IN ( SELECT TRKORR FROM e071 )'.
SELECT (string1)
INTO TABLE lt_trkorr
FROM (string2)
WHERE (string3).
However, if I use the static command, it runs fine:
select trkorr
from e070
into table lt_trkorr
where TRKORR IN ( SELECT TRKORR FROM e071 ).
I'm using WAS 6.10.
Thanks and Best Regards,
Tamas

Hi, I'm having the same problem with a dynamic subquery. My query is this:
select PEBELN PEBELP into table i_resultado
from EKPO as P
where (v_wher).
v_wher has the value: EXISTS ( SELECT * FROM EKPO AS P2 WHERE PEBELN = P2EBELN AND P2~EBELP = 30 )
The same query works fine if it is static.
The dump I receive says the following:
"An exception occurred. This exception will be dealt with in more detail       
below. The exception, assigned to the class 'CX_SY_DYNAMIC_OSQL_SEMANTICS', was
not caught, which                                                            
led to a runtime error. The reason for this exception is:                    
<b>The SELECT clause was specified in an internal table at runtime.              
It contains the field name "EXISTS", but this does not occur in any of        
the database tables listed in the FROM clause</b>."
It seems not to recognize the subquery.
Any idea?
