Hi ,
  Thanks for your help and responce.
  I already coded one small program using   commands . but its not working properly in perticular case.
   Here is the Code.
   From EKKO table the fucntion module fetching the data properly.
  SELECT SINGLE *  FROM EKKO
           INTO W_EKKO
                WHERE EBELN EQ P_EBELN.
        IF SY-SUBRC NE  0.                     
        CALL FUNCTION '/PBS/SELECT_INTO_TABLE'  
         EXPORTING                            
         ARCHIV    'CMM'                      
         OPTION   ''                           
         TABNAME    = 'EKKO'                  
         SCHL1_NAME = 'EBELN'                 
         SCHL1_VON  = P_EBELN                 
         SCHL1_BIS  = P_EBELN                 
     TABLES                                   
         I_TABELLE  = TAB20                   
     EXCEPTIONS  EOF    = 4                   
                 OTHERS = 2.                   
       LOOP AT TAB20 WHERE ( EBELN EQ P_EBELN ).  
           MOVE-CORRESPONDING TAB20 TO W_EKKO .     
           EXIT.                                  
        ENDLOOP.                                   
     ENDIF.                                     
<b><u>But when I use the function module to fetch from EKPO, its considering only EBELN , but not considering the EBELP .</u></b>
Its fetching all the line items related to this EBELN.
SELECT * UP TO 1 ROWS
     INTO CORRESPONDING FIELDS                    
         OF TABLE TAB23
  FROM EKPO
WHERE  EBELN EQ W_EKKO-EBELN                 
AND EBELP EQ P_EBELP.
ENDSELECT.                                                       
if sy-subrc ne 0.
CALL FUNCTION '/PBS/SELECT_INTO_TABLE'              
     EXPORTING                                
         ARCHIV         = 'CMM'              
         OPTION         = ''                 
         TABNAME         = 'EKPO'            
         SCHL1_NAME  = 'EBELN'               
         SCHL1_VON    = W_EKKO-EBELN        
         SCHL1_BIS       = W_EKKO-EBELN       
         SCHL2_NAME = 'EBELP'                 
         SCHL2_VON    = P_EBELP               
         SCHL2_BIS     = P_EBELP              
     TABLES                                   
         I_TABELLE  = TAB23                   
     EXCEPTIONS  EOF    = 4                   
                 OTHERS = 2.                  
    LOOP AT TAB23 WHERE ( EBELN EQ W_EKKO-EBELN AND  
     EBELP EQ P_EBELP ).                           
    MOVE TAB23-ebelp TO W_EKPO-ebelp.              
  ENDLOOP  .                                      
endif.
<u>Please check my code and give me some inputs.
  Is there any pre-conditions are needed.</u>
