Implementation BAPI ME_GUI_PO_CUST

[Former Member]

Hi all,

i implemented BAPI ME_GUI_PO_CUST to add an additional screen to purchase order

I copied the biggest part from the great example from SAP.

It is nearly working but i do not understand this code line:

<b> mmpur_dynamic_cast l_item im_model.</b>

What does it effect and what does it mean?

Thanks a lot.

The object im_model may include a header object as well as an item object.

The paramter im_name tells you which screen is processed.

Now you have to cast the "neutral" im_model to l_item or l_header.

See example:

DATA: l_header TYPE REF TO if_purchase_order_mm,

l_item TYPE REF TO if_purchase_order_item_mm,

ls_mepoheader TYPE mepoheader,

ls_mepoitem TYPE mepoitem.

CASE im_name.

WHEN 'SCREEN_ITEM'

mmpur_dynamic_cast l_item im_model.

ls_mepoitem = l_item->get_data( ).

...

WHEN 'SCREEN_HEADER'.

mmpur_dynamic_cast l_header im_model.

ls_mepoheader = l_header->get_data( ).

...

HI All,

If any one of you could possible tell me that whether or not

we can get the item data in the header tab.

it is as if i want to call the following code

WHEN 'SCREEN_HEADER'.

mmpur_dynamic_cast l_item im_model.

ls_mepoitem = l_item->get_data( ).

I tried this code but was not successful.

Could you tell me if it is possible??

Thanks in Advance,
