Adding custom fields to XD01 transaction

Question

Hi All,
I need to add custom fields to the Customer create transaction (XD01). Can anyone tell me the feasibility of having screen-exits or BADIs to acheive the same? I have searched for screen exits but could found none, and regarding BADI's i found these CUSTOMER_ADD_DATA, CUSTOMER_ADD_DATA_CS and CUSTOMER_ADD_DATA_BI. Unfortunately there is no default code assigned to these BADI's. Please tell me how we can acheive the requirement. we dont have any include too in the KNA1 table hence i feel going with APPEND structure.
Thank You

Hello Mahesh B
In short…
The Number field determines the display order of the Tabs on your new screen.  The i_taxi_fcode parameter is the text you entered, or will enter, in the Function Code field on the Label Tab Pages.
In long…
In the IMG activity “Prepare Modification-Free Enhancement in Customer Master Record”, you add a Screen Grp code (e.g. “Z1”) and a description. Then you select Z1 and double-click the Label Tab Pages folder on the left. 
Now, add one or more records in this Label Tab Pages screen.  Each record you add will cause a Tab to be displayed on your new Z1 screen (once you implement the screen with a program as described in earlier posts). 
The fields of the Label Tab Pages records are:
- NUMBER, which determines the order that the Tabs will be displayed;
- FUNCTION CODE, this is passed to the BAdI as i_taxi_fcode;
- DESCRIPTION, which becomes the Label displayed on the Tab; and
- ICON, which, if entered, will display beside the Label on the Tab.
Example records:
10, Z1_TR1, Tab1description, <blank icon field>
20, Z1_TR2, Tab2description, <Some Icon>
I prefixed my FUNTION CODEs with the screen group (e.g. Z1_TR1 and Z1_TR2).
More than one BAdI can be implemented in the system at the same time, so you should use the Screen Grp (e.g. Z1) and/or the Tab FUNCTION CODE (i_taxi_fcode - e.g. Z1_TR1) to determine when to execute your custom code. 
Below is an example implementation of the get_taxi_screen method in the customer_add_data_cs BAdI. 
If a user were to click on the second Tab of the Z1 screen group, the ‘Z1_TR2’ case would be executed and screen 200 would display on this Tab screen.  If the user clicked back to the first tab, the ‘Z1_TR1’ case would be executed and screen 100 would display on this Tab.
method if_ex_customer_add_data_cs~get_taxi_screen .
  case flt_val.
    when 'Z1'.
      case i_taxi_fcode.
        when 'Z1_TR1'.
          e_screen  = '0100'.
          e_program = 'Z_PROGRAM_NAME'.
          e_headerscreen_layout = ' '.
        when 'Z1_TR2'.
          e_screen  = '0200'.
          e_program = ‘Z_PROGRAM_NAME'.
          e_headerscreen_layout = ' '.
      endcase.
  endcase.
endmethod.
Hope this helps.
