Need help in module Pool programming.

Dear gurus

I'm stuck in a step of Module Pool program

Steps i used for enhancement in XK01.

1) i appended a structure in table LFA1 having two fields A and B.

2) then i went to IMG-> Logistic -> Business Partner-> Vendor -> Adoption of Customer's Own Master Data Fields -> Prepare Modification-Free Enhancement of Vendor Master Record ( Here i created my screen group Z1 without Function Code.

3) then i created below module pool program. of screen 9999 and in layout i added to fields to display A and B which i appended.

PROGRAM  ZSNAK_XK01.

TABLES: lfa1.
module status_9999 output.

endmodule.                 " status_9999  OUTPUT

module user_command_9999 input.

endmodule.

4) After this i wen to IMG-> Logistic -> Business Partner-> Vendor -> Adoption of Customer's Own Master Data Fields ->

Business Add-In: Processing of Master Data Enhancements ( Here i created my implementation on method CHECK_ADD_ON_ACTIVE and added this code

if i_screen_group eq 'Z1'.
e_add_on_active = 'X'.
endif.

5) then i went to IMG-> Logistic -> Business Partner-> Vendor -> Adoption of Customer's Own Master Data Fields ->

Business Add-In: Customer Subscreens. and created my implementation on method GET_TAXI_SCREEN where i have written this code.

e_screen = '9999'.
  e_program = 'ZSNAK_XK01'.
  e_headerscreen_layout = ''.

After activation when i execute t-code XK01 i see my button there after INFORMATION BUTTON when i click on it i get following error.

Incorrect screen type: Screen is incorrectly defined or used.

The attribute screen type with the values 'Normal Screen' and

'Subscreen' determines the use of the screen. If a normal screen is used

as subscreen or vice versa, an error occurs.

The screen "ZSNAK_XK01" 9999 has, in this respect, an inappropriate screen

type.

Please guide me

Regards

Saad Nisar.

I think you have defined the screen 9999 as normal screen. go to attributes tab of the screen and make it as "subscreen' (radio button) and activate
