how to read data.....and move it to internal table....
the requirement is as:
<b>Get the Participant details in an internal table IT_FINAL_PAR</b>
•     Loop through IT_PA0002 and move Personnel number (PERNR), Personnel ID Number (PERID), Last name  (NACHN), First name (VORNA), Gender Key (GESCH), Date of Birth (GBDAT) into a final internal table for Participant data IT_FINAL_PAR.
      Read the internal table IT_PA0006 to get the corresponding House Number and Street 
(STRAS), City (ORT01), Postal code (PSTLZ), State (STATE), 2nd address line (LOCAT) by comparing Personnel Number (PERNR)and move those retrieved field values to the final internal table for Participant data IT_FINAL_PAR.

Hi,
  you could try the following:
* work areas
data: W_PA0002 like line of IT_PA0002[],
      W_PA0006 like line of IT_PA0006[],
      W_FINAL_PAR like line of IT_FINAL_PAR[].
loop at IT_PA0002 into W_PA0002.
  clear W_FINAL_PAR.
* move values from IT_PA0002
  W_FINAL_PAR-PERNR = W_PA0002-PERNR.
  W_FINAL_PAR-PERID = W_PA0002-PERID.
* read address values from IT_PA0006
  read table IT_PA0006 into W_PA0006 with key pernr = W_PA0002-pernr.
  if sy-subrc = 0.
* move fields from IT_PA0006
    W_FINAL_PAR-STRAS = W_PA0006-STRAS.
  endif.
  append W_FINAL_PAR to IT_FINAL_PAR.
endloop.
