Delta update for 0FI_AR_4 DataSource

Question

Hi Experts,
We have a couple of reports (Infoprovider ODS) which are based on the 0FI_AR_4 DataSource. We have enhanced the Datasource and added 7 to 8 fields from SD and FI region. For enabling delta current mapping is: UPDMOD (R/3) field mapped to 0RECORDMODE (BW).
One of the enhanced FI field is Collection Specialist. If this Collection Specialist Master record is changed for a particular Customer, all the newly generated  Accounting Document shows the current Collection specialist but the already existing Accounting Document in BW are not getting converted to the current Collection Specialist.
Enhancement Code for 2 fields:
1. SELECT SINGLE KLIMK FROM KNKK INTO V_KLIMK
         WHERE KUNNR = l_s_dtfiar_3-KUNNR AND KKBER = l_s_dtfiar_3-KKBER.
     IF SY-SUBRC = 0.
         l_s_dtfiar_3-ZZKLIMK = V_KLIMK.
     ENDIF.
2. CLEAR: WA_UDMBPSEGMENTS.
    SELECT * FROM UDMBPSEGMENTS INTO WA_UDMBPSEGMENTS
                               WHERE PARTNER = l_s_dtfiar_3-KUNNR.
    ENDSELECT.
    IF SY-SUBRC = 0.
        SELECT * FROM UDM_SGMT_COMP INTO TABLE IT_COMP_CODE
                               WHERE COLL_SEGMENT = WA_UDMBPSEGMENTS-COLL_SEGMENT.
        LOOP AT IT_COMP_CODE.
          IF IT_COMP_CODE-COMP_CODE = l_s_dtfiar_3-BUKRS.
            l_s_dtfiar_3-ZZCOLL_SPECL = WA_UDMBPSEGMENTS-COLL_SPECIALIST.
          ENDIF.
        ENDLOOP.
     ENDIF.
     CLEAR   : IT_COMP_CODE
Please suggest what can be done to resolve the issue.
Thanks,
Vivek

Hi,
I hope you have written the codes in R/3 side.And whenever the Collection Specialist Master record is changed for a particular Customer, all the newly generated Accounting Document show the current Collection specialist but the already existing Accounting Document in BW will not converted to the current Collection Specialist since the data in BW is old data and no logic is written to convert the same.
Try to incorporate the logic to convert in BW also.
I could suggest is whenever there is change in Collection Specialist Master record , try to trigger a delat record generation that updates the old accounting doc withnew master in the delta load.
