Customer Screen add for ME21N

Hello !

i am using ME_GUI_PO_CUST to create customer screen on step by step some docu, but i do not know how to create screen 0001, because when i was trying to create screen 001 or 0100 on function group MEPOBADIEX,, system was asking development key to modify standard source.

is it correct ?

in method of Subscribe ,,

i defined as below;

  • the dynpro number to use

ls_subscriber-dynpro = '0001'.

  • the program where the dynpro can be found

ls_subscriber-program = 'SAPLMEPOBADIEX'.

  • each subscreen needs his own DDIC-Structure

ls_subscriber-struct_name = 'CI_EKKODB'.

where can i create screen 0001 ?

Thank you & Best Regards;

See SAP Note 496083 - FAQ: Customer enhancements (User Exits) in purchasing

You have this question and answer:

I implemented the 'ME_GUI_PO_CUST' Business Add-In to display customerspecific
tab titles in the EnjoySAP purchase order. They are only shown in
display mode (ME23N) however, not in create or change. Why?
You may have forgotten to assign a field status to the user-defined fields
on these tabs. As a result, the system automatically interprets the field
status as 'hidden' in create and change modes. However if a tab contains
only hidden fields, then the entire tab is set to hidden. In display mode,
fields without a field status are automatically set to display. That is why
the tab is displayed in this case.
To assign a field status to the user-defined fields, use the methods
provided for this purpose in the Business Add-In 'ME_PROCESS_PO_CUST'
(compare sample source code in the FIELDSELECTION_ITEM method).

The question is to write a code as this in method FIELDSELECTION_HEADER (or ITEM) in BADI 'ME_PROCESS_PO_CUST'

  data: l_persistent type mmpur_bool,
        l_changeable type mmpur_bool,
        l_header type mepoheader.

  l_persistent = im_header->is_persistent( ).
  l_changeable = im_header->is_changeable( ).
  l_header = im_header->get_data( ).

  if condition.
    if condition.
      if l_changeable = 'X'.
        <fs>-fieldstatus = '.'. " READY FOR INPUT
        <fs>-fieldstatus = '*'. " view
      <fs>-fieldstatus = '-'.    "SUPRESS IT
     <fs>-fieldstatus = '-'.   "suprress it

I hope this helps you
