Hi,
  Use trx SE19 to implement your BADI: create an ZME_PROCESS_PO_CUST using ME_PROCESS_PO_CUST as definition.
Now in Interface Tabs you can see the METHODs you can use as "user-exit", in particular there's PROCESS_ITEM to manage items data.
You have to write your code into this method.
This method has IM_ITEM like parameter in its interface, and it's like the type IF_PURCHASE_ORDER_ITEM_MM.
This type has the method IF_LONGTEXTS_MM~SET_TEXT, you can try to use it to set your text in item.
This is code for example:
DATA: TLINE TYPE MMPUR_T_TEXTLINES.
CALL METHOD IM_ITEM->IF_LONGTEXTS_MM~SET_TEXT
EXPORTING
IM_TDID = <YOUR ID>
IM_TEXTLINES = TLINE.
So you should read the text you want to copy and pass it to TLINE.
You can use the METHOD PROCESS_HEADER to read the text you need. This METHOD has IM_HEADER as parameter and it's like the type IF_PURCHASE_ORDER_MM, this type has the method IF_LONGTEXTS_MM~GET_TEXT to read header logn text.
Anyway while you're in implementation of the BADI go to:
GoTo->Sample Code
Here you can try an example how to implement the method you need to use.
