Hi,

You should use two BAdi's:

ME_GUI_PO_CUST

ME_PROCESS_PO_CUST

For sample implementation look at transaction SE18,

menu Jump to->Sample code->Display.

For ME_GUI_PO_CUST you should at least implement methods:

IF_EX_ME_GUI_PO_CUST~SUBSCRIBE,

IF_EX_ME_GUI_PO_CUST~MAP_DYNPRO_FIELDS.

For ME_PROCESS_PO_CUST you should at least implement method:

IF_EX_ME_PROCESS_PO_CUST~FIELDSELECTION_ITEM.

Example codes:

You must create your own function group with subscreen (see documentation)
in this example FM name is ZIT_MM_PO_ENH
ZIT_MM_PO_ENH_EXTRAFLDS name of the structure containg field ZZUNSPSC

method IF_EX_ME_GUI_PO_CUST~SUBSCRIBE.

data: ls_subscriber LIKE LINE OF re_subscribers.

check im_application = 'PO'.

check im_element = 'ITEM'.

clear re_subscribers[].

ls_subscriber-name = subscreen1.

ls_subscriber-dynpro = '0100'.

ls_subscriber-program = 'SAPLZIT_MM_PO_ENH'.

ls_subscriber-struct_name = 'ZIT_MM_PO_ENH_EXTRAFLDS'.

ls_subscriber-label = 'Descripton'.

ls_subscriber-position = 15.

ls_subscriber-height = 8.

APPEND ls_subscriber TO re_subscribers.

endmethod.

method IF_EX_ME_GUI_PO_CUST~MAP_DYNPRO_FIELDS.

field-symbols: <mapping> like line of ch_mapping.

loop at ch_mapping assigning <mapping>.

case <mapping>-fieldname.

when 'ZZUNSPSC'. <mapping>-metafield = '90000100'.

endcase.

endloop.

endmethod.

method IF_EX_ME_PROCESS_PO_CUST~FIELDSELECTION_ITEM.

data: ls_fieldselection like line of ch_fieldselection.

read table ch_fieldselection with key metafield = '90000100'

into ls_fieldselection.

if sy-subrc = 0.

ls_fieldselection-fieldstatus = '*'.

modify ch_fieldselection from ls_fieldselection index sy-tabix.

endif.

endmethod.

Thanks,

Nagaraju.

Hi,

Check if any screen exit is avialable for the transaction. If so you can do it with the screen exits.
