Customer Creation - Want to pass custom field data to KNA1(Customer Master)

Question

Hi,
I have created BAPI for customer creation which uses standard program RFBIDE00 for customer creation.
I have appended new custom field(ZZATTR1) in the table KNA1 and its currosponding stucture used in the standard program BKNA1.
Import parameters of my BAPI is one structure which is having this custom field, on executing this BAPI it creates the customer but data which I give through this field is not getting transfered in the table KNA1.
This sstandard progaram uses file to containing customer information, In the BAPI I on the data from the structure to the file and further it gets submitted to the program.
My requirement is to pass the data of teh custom field which I have created, How to achieve this ?
Pls Suggest.
Regards
Vishal

Hi Vishal,
When implementing a customer exit (i.e. field, user etc) have you ever wanted to be able to read additional
field values available in the main SAP program but not available in your exit. Now with the use of
field-symbols you can have access to any field available in the main SAP program. The code below
demonstrates how this is done within a field exit on BSTNR which can be tested using transaction
ME21. Information on creating field exits can be found here. 
FUNCTION field_exit_bstnr.
""Local interface:
*"  IMPORTING
*"     REFERENCE(INPUT)
*"  EXPORTING
*"     REFERENCE(OUTPUT)
create field symbol
  FIELD-SYMBOLS: <status>.
Assign value of variable from calling prog to field symbol
  ASSIGN ('(SAPMM06E)RM06E-BSART') TO <status>.
Display value retrieved in message
Note: Messages of type i and w are not allowed
  IF sy-subrc = 0.
    MESSAGE e003(zr) WITH <status> 'kkk'.
  ENDIF.
ENDFUNCTION.
Rewords some point if it is helpful.
