Loop at table with unspecified type but with where-condition

Question

Hi,
Doing a loop over an internal table with unspecified type and in addition using a condtion may be done as follows: Thereby the
condition would be "... WHERE parentid EQ i_nodeid" if the type of <it_htab> would be static. However dynamic specification of a component through bracketed character-type data objects is not possible.
FIELD-SYMBOLS: <it_htab> TYPE STANDARD TABLE,
                                <wa_htab> TYPE ANY,
                                <parentid> TYPE rsparent.
  ASSIGN me->ref_htab->* TO <it_htab>.
  LOOP AT <it_htab> ASSIGNING <wa_htab>.
    ASSIGN COMPONENT 'PARENTID' OF STRUCTURE <wa_htab> TO <parentid>.
    CHECK <parentid> EQ i_nodeid.
  ENDLOOP.
Since you have to loop over the whole table and to check within the loop whether the condition is fullfilled, this is rather bad for performance.
Questions: Are there any tricks to do this better?
Best Regards and Thank you,
Ingo

only if you have the upcoming 7.0 EhP2 (Kernel 7.02 or 7.20) the following dynamic where works:
DATA cond_syntax TYPE string.
cond_syntax = `parentid = i_nodeid`.
LOOP AT <it_htab> ASSIGNING <wa_htab>
                       WHERE (cond_syntax).
in older releases you would have to use program generation to achieve a dynamic where... .
