Retrieving previous header data in PO line in IF_EX_ME_PROCESS_PO_CUST

[Former Member]

Hi,

How can I call method get_previous_data included in parameter re_header from method get_header, included in parameter im_item from method process_item (implementation of badi interface IF_EX_ME_PROCESS_PO_CUST)?.

It should be something similar to

call method im_item->re_header->get_previous_data ...

but the system does not allow this.

Rgds,

Jose

Hello Jose

The interface method <IF_EX_ME_PROCESS_PO_CUST>->process_item imports im_item which is of type IF_PURCHASE_ORDER_ITEM_MM.

Now you have to call method im_item->get_header:

[code]DATA:

lif_header TYPE REF TO IF_PURCHASE_ORDER_MM.

CALL METHOD im_item->get_header

RETURNING

re_header = lif_header.

• The functional call looks like:

lif_header = im_item->get_header( ).

*$Comment: Im am not sure if a cast to a class is required, e.g.:

DATA:

lo_header TYPE REF TO <class implementing IF_PURCHASE_ORDER_MM>.

lo_header ?= im_item->get_header( ).

• Finally call your required method:

DATA:

ls_header TYPE MEPOHEADER.

CALL METHOD lif_header->GET_PREVIOUS_DATA

EXPORTING

ex_data = ls_header.[/code]

Thanks Uwe, one of this days I will have to decide to dive deep into objets.

By the way, the system gives me an error message when trying to reward your points.

Best regards,

Jose
