You can specify condition of where clause using intenal table using option "FOR ALL ENTRIES IN ". When you apply this option please make sure that the internal table has at least one row. If internal table has no entry, system will ignore this option.

Example

DATA: itab TYPE TABLE OF vbak WITH HEADER LINE,
      itab2 TYPE TABLE OF vbap WITH HEADER LINE.
SELECT * INTO TABLE itab FROM vbak
         WHERE vbeln BETWEEN ’1000000000’ AND ’4999999999’.
IF NOT itab[] is initial.
  SELECT * INTO TABLE itab2 FROM vbap
           FOR ALL ENTRIES IN itab
           WHERE vbeln = itab-vbeln 
             AND matnr LIKE ’F%’.
ENDIF.
