Update Routine ... Help me Please--VERY URGENT

Question

Hi All ,
I Moving data from Cube to ODS . Let me explain abt the records in the cube .
There are 6 key figures in the cube as well as dimensions, UNIQKEY TRANSACTION is One Dimension and ARTICLE is another dimension which is having an Navigational attribute called CORE ELEMENT.
I am showing the data with those two dimension and the key figures which are to be used in the routine.
Charc----
Key Figures
UNIQKEY-ARTICLE-Coreelement--
billqty     
in base unit
A00N----1006330--1--
10.5
A00M -
1006320----2--
2.5
A00P-----1006330--1--
10.5  
A00P-----1006320--2--
2.5
A00Q-----1006320--2--
2.5
A00Q-----1006340--3--
10.5
Now Lets see what the core element numbers mean,
core element 1 means -- fuel .
Core elemnet other 1 -- food .   
I need to move these data into ODS Which will have an extra field called No of items in the transaction --ITEMS.For this i need to write  a routine .
The Logic is ...
1.if Materail is of type 1(Means if the core element - 1)
I need to Populate the No of items in tnx = 1 .--ITEMS.
2.If Material is of type(Means if the core element)2or 3 I need to populate the billing quantity to the no of transcations.--ITEMS
3. If the Uniqkey tanscation contains two line items as  suppose that you have 20 litres of fuel and 2 cans of coke, then No of Items in the transaction should be 3 and Billing Quantity in BUoM 22
billing quantity in BUoM = 20 litres for the first line item and 2 for the second line item...
then as the first line item is fuel, field No OF Items in the Transcation should be 1 (replacing the 20) + 2 = 3
so the final result in the ODS should be billing quantity in BUoM = 22 and The Items in the Transcation= 3
So the ODS Data should look like this.
UNIQKEY--billqty--
ITEMS
in base unit 
A00N--10.5--
1
A00M--2.5--
2.5
A00P--13--
3.5
A00Q--13--
12.5  
NOTE : IN the ODS only the UNIQKEY IS THE KEY FIELD and the rest are DATA FIELDS.
I Posted this one before also. But didnt get proper responses.
I am Pasting the piece of code which I have written . This code will work for the first two records in the cube , But it is failing for the UNIQKEY Transcation having Line items.
PROGRAM UPDATE_ROUTINE.
$$ begin of global - insert your declaration only below this line  -
TABLES: /BI0/PMATERIAL.
DATA: TITEMS LIKE /BIC/AZPOCODS00-/BIC/ZTITEMS,
       CORE_ELEMENT like /BI0/PMATERIAL-RPA_WGH1.
$$ end of global - insert your declaration only before this line   -
FORM compute_data_field
  TABLES   MONITOR STRUCTURE RSMONITOR "user defined monitoring
  USING    COMM_STRUCTURE LIKE /BIC/CS8ZPOCTUS04
           RECORD_NO LIKE SY-TABIX
           RECORD_ALL LIKE SY-TABIX
           SOURCE_SYSTEM LIKE RSUPDSIMULH-LOGSYS
  CHANGING RESULT LIKE /BIC/AZPOCODS00-/BIC/ZTITEMS
           RETURNCODE LIKE SY-SUBRC "Do not use!
           ABORT LIKE SY-SUBRC. "set ABORT <> 0 to cancel update
$$ begin of routine - insert your code only below this line        -
fill the internal table "MONITOR", to make monitor entries
check not COMM_STRUCTURE-material is initial.
  select SINGLE RPA_WGH1
        INTO CORE_ELEMENT
        from /BI0/PMATERIAL
        where
        material = COMM_STRUCTURE-material
        and  OBJVERS <>'D'.
   IF CORE_ELEMENT EQ '1'.
   TITEMS = '1'.
     CALL FUNCTION 'CONVERSION_EXIT_ALPHA_OUTPUT'
       EXPORTING
         input         = titems
      IMPORTING
        OUTPUT        = titems
   ELSE.
   TITEMS = COMM_STRUCTURE-BILL_QTY.
   ENDIF.
result value of the routine
  RESULT = TITEMS..
if abort is not equal zero, the update process will be canceled
  ABORT = 0.
$$ end of routine - insert your code only before this line         -
PLease give me ideas on how to acheive this . As I am not Aware of ABAP very well.. PLease try to give me the code. I hope one of you may got the same requirement before.
Its very urgent and I need to deliver it today itself.
Thanks in advance , you can mail me to [email protected]. If anybody intersted to discuss this Issue they can reach at [phone].

Answer 1

Hi ,
While I am moving the data from cube to ods . I need to create the update rules with cube -- 8cube . WHen i am doing this the billqty is a key figure in cube so that is not a problem but the ITEMS is not there in the cube ,SO for that I need to write a routine to populate that one.
Its strange but the user what to analyse with the UNIQKEY transaction. And these objects will be added as navigational attributes to the Characteristic. as it acts as another dimension.
He wants to laod these from ODS to Master data -Characteristic.
to say for each transcation hpw many items are getting sold.
