Runtime error using range table in select query

Question

I have to select tcodes from table tstc, based on the entries in ust12,
the entries in ust12-von and ust12-bis, these contains wild charcters also,  and i have to selct all the tcodes  from von to bis.
so ia m preparing a range table for the entries in ust12, and querying table tstc, then i am getting a runtime error with following description.
'If the problem occurred because an excessively large table was used
in an IN itab construct, you can use FOR ALL ENTRIES instead.'
but how can i use FOR ALL ENTRIES here, because if von = A* and bis = AB*,then i ahve to read all the entries from AAAA till ABZZ (may be something like this),
is there any way to write this query, with out runtime error.
there are total 15000 entries in ust12, i am preparing range table for 3000 entries each and querying tstc.
Thanks in advance
Best Regards

Hi,
first write a select on ust12 based on ust12-von and ust12-bis.
eg: select von bis from ust12 into table gt_ust12
                           where von LIKE 'A%'
                               and bis LIKE 'AB%'.
now write another select for tstc for all entries in gt_ust12...
Hope it helps
