How to enable the Delta for the data source 0CO_OM_OPA_7

Question

Hi Experts,
I have a business content data source 0CO_OM_OPA_7 and I need to activate and enable Delta for this data source.
This data source is activated (but not delta enabled) and used for full load in my system for the past three year. As this is a full load this data source is carrying more than 4 million records every day with adding 2 millions records every year. The load takes every day 4 to 5 hours for completion.
Now I need to enable the delta for this data source. To enable the delta for this data source I used the transaction RSA5 and clicked on the 'Activate DataSources' but the data source is not enabled the 'Delta'
I have also checked in the RSA6 transaction, the check box for 'Delta' is not checked for this data source.
Can anybody help in enabling the 'Delta' for this data source.
Thanks in Advance
Narendra

Hi,
DS "0CO_OM_OPA_7" won't support deltas, so load to ODS then to Cube. Else delete the overlaping request then load this you can set in InfoPackage level.
You check any Period/Month fields in 0CO_OM_OPA_7 then write simple routine in Infopackage and the set the overlaping deletion.
Use the followng code and change it for your requirement in Infopackage level.
I'm using 0CO_PC_01 DataSource, so it won't have delta so I'm using the following code in InfoPackageag and set delete overlaping req. So eveyday it will delete the old req for that period and then it will load data againg for that period (Full loads).
DATA: l_idx LIKE sy-tabix,
        zzdate LIKE sy-datum,
        zzbuper LIKE t009b-poper,
        zzbdatj LIKE t009b-bdatj,
        zzperiod(7) TYPE c.
  READ TABLE l_t_range WITH KEY
       fieldname = 'FISCPER'.
  l_idx = sy-tabix.
  zzdate = sy-datum - 1.
  CALL FUNCTION 'DATE_TO_PERIOD_CONVERT'
    EXPORTING
      i_date               = zzdate
*             I_MONMIT             = 00
      i_periv              = 'V3'
           IMPORTING
     e_buper              = zzbuper
     e_gjahr              = zzbdatj.
*           EXCEPTIONS
*             INPUT_FALSE          = 1
*             T009_NOTFOUND        = 2
*             T009B_NOTFOUND       = 3
*             OTHERS               = 4
  IF sy-subrc <> 0.
* MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
*         WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
  ENDIF.
  CONCATENATE zzbdatj zzbuper INTO zzperiod.
  l_t_range-low = zzperiod.
  l_t_range-option = 'EQ'.
  l_t_range-sign = 'I'.
  MODIFY l_t_range INDEX l_idx.
Thanks
