Reading masterdata of attribute in BI 7.0

Question

Hello Gurus
I have the following situation:
I am creating a transformation from an ODS to the Cube. I have an InfoObject in the cube which should be populated based on the value of another InfoObject in the ODS (which is a navigation attribute of another characteristic present in the ODS).
What should be the best approach for this
Thanks

Hope I can help you.
The scenrio is simplied based on CVS file, our real scenrio are logistical data model which date are  from shipping item, order itme data.
We have a infoobject named material which has a attribute material type. its data like this:
Material     Material_Type
MAT001     ZDIE
MAT002     ZIFG
MAT003     ZDIE
MAT004     ZIFG
We hava a another DSO named delivery ODS which data like below:
Material     DeliveryDoc     DeliveryItem     DeliveryDate
MAT001     12345678     1     20070501
MAT002     12345679     1     20070502
MAT003     12000000     1     20070503
MAT004     12000001     1     20070504
We have a another DSO named invoice ODS which data like below:
Material     InvoiceDoc     InvoiceItem     Billingdate     ReferedDeliveryDoc     ReferedDeliveryItem
MAT001     30000000     1     20080101     12345678     1
MAT002     30000001     1     20080102     12345679     1
MAT003     30000002     1     20080103     12000000     1
MAT004     30000003     1     20080104     12000001     1
Our business requirements is:
1. Need to create the third DSO which will merge data from the above two DSOs.
2. the third DSO name "Deliveried sales order info DSO" which has the following model:
   Material     InvoiceDoc     InvoiceItem   DeliveryDoc  DeliveryItem  Act_Goods_Issue_DATE
3. The Act_Goods_Issue_DATE will be filled from delivery ODS or invoice ODS, the rule is if material type is "ZDIE" which means it is a non-physical product (service product), the Act_Goods_Issue_DATE should be filled from Billingdate of invoice ODS. if the material type is "ZIFG" that means it is a physical product. the the Act_Goods_Issue_DATE should be filled from the DeliveryDate of delivery ODS.
Implement mothod:
1. We create a transformation from delivery ODS to "Deliveried sales order info DSO", most infoobjects were mapped directly.
2. we create a transformation from invoice ODS to "Deliveried sales order info DSO".  we create a start routine for Act_Goods_Issue_DATE. the main code is like below.
$$ begin of global - insert your declaration only below this line  -
    DATA: G_MATERIAL TYPE TABLE OF /BIC/PIO_MATG.
    DATA: G_DSO_DELI TYPE TABLE OF /BIC/AZ_ODS200. 
$$ end of global - insert your declaration only before this line   -
$$ begin of routine - insert your code only below this line        -
... "insert your code here
*--  fill table "MONITOR" with values of structure "MONITOR_REC"
*-   to make monitor entries
... "to cancel the update process
   raise exception type CX_RSROUT_ABORT.
Get material master date into the internal table G_MATERIAL
SELECT * INTO TABLE G_MATERIAL
      FROM /BIC/PIO_MATG
       FOR ALL ENTRIES IN SOURCE_PACKAGE
     WHERE /BIC/IO_MATG = SOURCE_PACKAGE-/BIC/IO_MATG.
    SORT G_MATERIAL BY /BIC/IO_MATG.
Get delivery DSO active table data into the internal table G_DSO_DELI
    SELECT * INTO TABLE G_DSO_DELI
      FROM /BIC/AZ_ODS200
        FOR ALL ENTRIES IN SOURCE_PACKAGE
      WHERE /BIC/ZDOC002 = SOURCE_PACKAGE-/BIC/ZDOC001
      AND /BIC/ZITEM02 = SOURCE_PACKAGE-/BIC/ZITEM0001.
    SORT G_DSO_DELI BY /BIC/ZDOC002 /BIC/ZITEM02.
$$ end of routine - insert your code only before this line         -
3. Then add the fields Material,Billingdate,ReferedDeliveryDoc,and ReferedDeliveryItem as input for the infoobject Act_Goods_Issue_DATE and write transfer routine like below:
$$ begin of routine - insert your code only below this line        -
    ... "insert your code here
*--  fill table "MONITOR" with values of structure "MONITOR_REC"
*-   to make monitor entries
    ... "to cancel the update process
   raise exception type CX_RSROUT_ABORT.
    ... "to skip a record"
   raise exception type CX_RSROUT_SKIP_RECORD.
   result value of the routine
   DATA : W_MATERIAL TYPE /BIC/PIO_MATG.
    DATA : W_DELIVERY TYPE /BIC/AZ_ODS200.
    READ TABLE G_MATERIAL INTO W_MATERIAL WITH KEY /BIC/IO_MATG =
    SOURCE_FIELDS-/BIC/IO_MATG
    BINARY SEARCH.
    IF SY-SUBRC EQ 0.
      IF W_MATERIAL-/BIC/IO_MATTY = 'ZDIE'.    // if the material is a service product.
        RESULT =  SOURCE_FIELDS-/BIC/ZDATE01.
      ELSE.
if  the material is a non service product, then search internal table G_DSO_DELI to get DeliveryDate.
        READ TABLE G_DSO_DELI INTO W_DELIVERY WITH KEY
               /BIC/ZDOC002 = SOURCE_FIELDS-/BIC/ZDOC001
               /BIC/ZITEM02 = SOURCE_FIELDS-/BIC/ZITEM0001
               BINARY SEARCH.
        IF SY-SUBRC EQ 0.
Assign  DeliveryDate "/BIC/ZDATE02" to result.
          RESULT =  W_DELIVERY-/BIC/ZDATE02.
        ENDIF.
      ENDIF.
    ENDIF.
$$ end of routine - insert your code only before this line         -
