You can specify condition of where clause using intenal table using option "FOR ALL ENTRIES IN <itab>". 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.
