For Reversal Document Maintainence

Question

Hi
   For SAP NetWeaver BI, we are using the standard data source '0UC_SALES_STATS_01'  for  Billing Analysis . We are facing one issue regarding this.
The selection creteria for this data source is BUDAT(Posting Date of Invoice Doument) only .
For Example we are extracted the data for the BUDAT = 31.01.2006.  In this scenario, assume one Business Partner Number is 1000071173, Consumption is 100 Units and Bill Amount is 500 Rs(INR) for a particular month bill. Now we extract the data from R/3 to BI.After Extraction it will move from R/3 Server to BW Server and it will load into the PSA and then in ODS.
After some days,for some reason we have to reverse the bill and to reissue a corrected bill on the same posting date (i.e.31.01.2006).So for that Business Partner 1000071173,say, Consumpiton is revised to 75 Units and Bill Amount is revised to Rs 375 INR. So the previous Invoice Document is reversed (Full Reversal-Invoice and bill document both) and the new bill has been made for him with 75 units and Bill Amount Rs. 375 INR. When we extract this data again i.e BUDAT 31.01.2006 , we will get the 2 documents one for reversed and one for Corrected. After Extraction from R/3 to BI , In PSA we will get 2 more documents for him.  After transfering this two documents into ODS we will get total three documents for that Business Partner for a particular month bill. 
Doc 1. Very first time i.e (in the Extraction Date 31.01.2006 with amount Rs 500 INR )
Doc 2. Reverse Document for the Above Doc.
Doc 3. For Corrected Bill.(Invoice document with Rs 375 INR)
In our Business scenario,it is required that we have to display only the recent corrected value in any of the report.So in the time of extraction how can we overwrite or delete the previous records and to keep only the recent corrected value?

Hi There,
There shouldn't be any overwrite or deletion of previous records in BI.  In the R/3 system which is the ISU system, a reversal invoice should carry a negative consumption and bill amount.  For your example, after extraction and data loaded into BI:-
Doc 1 in BI should have 100 Units and 500 INR   (Original or yr very first invoice)
Doc 2 in BI should have -100 Units and -500 INR (Reversal Invoice)
Doc 3 in BI should have 75 Units and 375 INR.    (Rebill Invoice)
When you run a query for the respective Business Partner for that posting period, Doc 2 should offset Doc 1.  As a result you should get result from Doc 3 only, which is 75 Units and 375 INR.
