2lis_11_vaitm vs 2lis_11_vahdr

Question

Hi gurus,
I need to enhance 2lis_11_vaitm with VDATU field (sold-to party's Requested Delivery Date.) Actually this extractor contain field with same name and different meaning (Update date for statistics update).
The reason is we've done it with badi&z-field but there are a lot of data and primitive calculation show us that we'll spend extra hours and extra load to our erp enhancing our 2lis_11_vaitm.
So i wonder is there any way to change standart field in item extractor? or maybe some way to cheat it?
PS They way described below is found on sap site -
DataSources 2LIS_11_VAITM and 2LIS_11_VASCL. In 2LIS_11_VAHDR however,
the field VDATU contains the sold-to party's Requested Delivery Date.
If you need a field that can take over the Update Date for Statistics
Update function, proceed as described in SAP Note 719603.

Answer 1

Gurus please be so kind to check my abap tuning and guess if something can be done extra.
WAS
+loop at c_t_data assigning <l_s_data>.
select single vdatu into (<l_s_data>-zvdatu)
from vbak where vbeln=<l_s_data>-vbeln.
endloop.+
NOW
DATA: BEGIN OF wa_vbak,
           vbeln LIKE vbak-vbeln,
           vdatu LIKE vbak-vdatu,
        END OF wa_vbak.
DATA: it_vbak LIKE TABLE OF wa_vbak,
           l_vbak like line of wa_vbak.
select vbeln vdatu from vbak
for all entries in c_t_data
where vbeln=c_t_data-vbeln
into table it_vbak.
sort it_vbak by vbeln descending.
loop at c_T_data assigning <l_s_data>/
read table it_vbak with table key vbeln=<l_s_data>-vbeln into l_vbak.
<l-s-data>-zvdatu=l-vbak-vdatu.
endloop.
