Accessing private data

[Former Member]

Hi to all.

I use an implementation of badi ME_PROCESS_PO_CUST to find changes of subcontracting purchase orders.

In that i use the mathod as IF_EX_ME_PROCESS_PO_CUST~POST.

Here i use the importing parameter im_ebeln for finding the purchase order number.

And i want purchase order item also.

For that i find the sorted internal table as

{O:294*\CLASS=CL_PO_HEADER_HANDLE_MM}-MY_BADI_QUEUE from me_header object.

But my problem is how to access that internal table data.

Please guide me.

Thanks in advance.

You cannot access that internal table because it is a private attribute.

But you can get the purchase order items by calling the GET_ITEMS method.     There are lots of variations but it should look something like this:

    DATA: lo_po_handler TYPE REF TO cl_po_header_handle_mm,

               lt_poitem_obj TYPE purchase_order_items.

    lo_po_handler ?= im_header.

    CALL METHOD lo_po_handler->if_purchase_order_mm~get_items
    RECEIVING
      re_items = lt_poitem_obj.

Hope that helps.

Its working but i have one doubt by using of method lo_po_handler->if_purchase_order_mm~get_items i can find one standard table.

In that table i have one item field but it is showing {O:656*\CLASS=CL_PO_ITEM_HANDLE_MM}.

Plz guide me from this object how can i found item number.plz guide me.

To get to the item number, you need to loop at the table returned by the GET_ITEMS method, and call another method, GET_DATA.

Something like this:

DATA: ls_poitem_obj TYPE purchase_order_item,

           lo_po_item_handler TYPE REF TO cl_po_item_handle_mm,

           ls_poitem TYPE mepoitem.

LOOP AT lt_poitem_obj INTO ls_poitem_obj.

     lcl_po_item_handler ?= lw_poitem_obj-item.
    CALL METHOD lcl_po_item_handler->if_purchase_order_item_mm~get_data
    RECEIVING
      re_data = ls_poitem.

ENDLOOP.

Structure LS_POITEM should contain the item number, field EBELP.

Use the objects provided in the BAdI, that could look like :

INCLUDE mm_messages_mac.
 DATA: lt_items TYPE purchase_order_items,
       lo_item TYPE purchase_order_item,
       lt_accountings TYPE purchase_order_accountings,
       lo_accountings TYPE purchase_order_accounting. 
       " etc.
 DATA: new_header TYPE mepoheader,
       old_header TYPE mepoheader,
       new_item TYPE mepoitem,
       old_item TYPE mepoitem,
       new_accounting TYPE mepoaccounting.
       " etc.
 *------------------------------------------------------------------
 CHECK me->trtyp NE 'A'.
 mmpur_context mmcnt_context_badi.
 *------------------------------------------------------------------
 * Header
 new_header = im_header->get_data( ).
 old_header = im_header->get_persistent_data( ).
 *------------------------------------------------------------------
 * Items
 lt_items = im_header->get_items( ).
 LOOP AT lt_items INTO lo_item.
   new_item = lo_item-item->get_data( ).
   old_item = lo_item-item->get_persistent_data( ).
   " accounting
   lt_accountings = lo_item-item->get_accountings( ).
   LOOP AT lt_accountings INTO lo_accountings.
     " etc.

Then compare old and new values item per item, also available for accounting GET_ACCOUNTINGS, delivery schedule GET_SCHEDULES and conditions GET_CONDITIONS.
