Duplicates are loadnig into the ods

Question

Hi guys,
im going through one issue related to line item ods for AR.
coming from 0fi_ar_4 datasource.
In  BW, the segemnt filed ( which is profit center field in the "bfod_a" table) is considered as key in the line item ods.
due to some user changes to this field in the r/3 ( p03/100) system, we are getting two records as duplicates.
like
  docno  lineitem segment  amount.
   111      1            blank       10000   -
first time
later end user changes the segment feild value
   111      1            66             10000    secound time
since segment is key in ods, both are  updating
but we require the latest one.and i cannot remove from key part .
the reason for the segment( profit center) as key field, is like
for every company code, dcoument no , we can have more  line items each line item can have different amount
so  to distinguish the each line item amount , segment( profit center in r/3 ) is taken as key.
but with segment( profit cener in r/3) as key, we are getting duplicates.
so we require a field which has dependendy on profit center field and able to distinguish the line items for same
document number.
or any techinical code in r/3 which i can apply.
plzzz help on this
if you have any questions on this please call on this no : [phone].

As mentioned above, letting users load the data is not a best practise. But if you still need to achieve this...
In the settings of the ODS, check if the automatic activation is turned on ? If Yes, then simultaneous loading can sure cause problems (lock issues). So go ahead and turn this off !
Once the users are done loading the data into ODS, then activate these requests. You can choose to do so all at once (without condensing them into single request is what I would advice).
Hope this helps.
