I am not geting all the records in TCRT for a perticular sequnce number ?

Question

Hi All,
I  not geting all the recotrds in TCRT table  what ever the records i can see in transaction : PC_PARESULT for a perticular employee of perticular sequence neumber.
My code is like this : for the cumyr = '2008' i am geting values but cumyr = '2007' i am not geting values . But actually records exist for that condition as i see through PA_PCRESULT.
cd-key-pernr = pernr-pernr.
  rp-imp-c2-cu.
  SORT rgdir BY paydt DESCENDING.
  LOOP AT rgdir.
CHECK: rgdir-paydt BETWEEN p_detryr_low AND
                               p_detryr_high,
    rx-key-pernr = cd-key-pernr.
    UNPACK rgdir-seqnr TO rx-key-seqno.
    rp-imp-c2-ru.
    EXIT.
  ENDLOOP.
IF sy-subrc = 0.
  LOOP AT tcrt WHERE lgart = '/303' AND
                         ctype = 'Y' AND
                         taxau = 'FED' AND
                         cumyr = '2008'.
    v_betrg 1= v_betrg + tcrt-betrg.
  ENDLOOP.
LOOP AT tcrt WHERE lgart = '/303' AND
                         ctype = 'Y' AND
                         taxau = 'FED' AND
                         cumyr = '2007'.
    v_betrg 2 = v_betrg + tcrt-betrg.
  ENDLOOP.
     Thanks ,

You may not expressly be using all the RAM in your machine but OS X will, whether you know it or not.
Each time you read a file from disk, whatever was read is cached by the system; when the file or program is no longer in use, the memory is marked free for the system to recover for other purposes but as long as it remains in memory the next time you need to access that disk information it's simply read from memory.
The more RAM, the more disk data is kept around and the faster your machine will operate until that memory needs to be recovered or you reboot (or otherwise flush the disk cache.)
