BW report integration in Portal/PC-UI based on a BP at runtime

Question

Hello,
we have created a BW report "Customer Overview" and want this report to be called from the Account BSP iView (within the context): The selected Business Partner should be automatically transferred to the report, the BW report should receive the BP ID at runtime.
There is the similar standard overview called "Fact Sheet", but we decided to not use it, but instead our own report. We are on CRM 4.0, Netweaver Portal (EP6.0), BW 3.5 and Business Package for mySAP CRM (not the Business Productivity Pack).
We have tried to use the same method "factsheet" for linking to our BW web template using the button "Fact Sheet" in the Account BSP iView. We created therefor a new iView (based on com.sap.pct.crm.bwreport.BWContainer), filled the required parameter and placed it on our own fact sheet page. The resulting test URL of the new iView looks fine:
http://[host]:[port]/sap/bw/BEx?cmd=ldoc&sap-language=EN
&TEMPLATE_ID=TPCRM1001&FILTER_IOBJNM_1=0BPARTNER
The object link from the 'Fact Sheet' button to our fact sheet page works, however the BP id is not passed or the BW template does not process it.
How is the business partner ID transferred at runtime from Account BSP?
What have to be done on the BW report in order to receive / require the parameter FILTER_IOBJNM_1 (i.e. BP ID) and display the overview for this particular customer?
Further questions:
Is this right way to achieve the display of BW data of a particular business partner?
Is there another way to do this?
Thanks for any information on how to integrate BW report that requires a BP ID in the portal...
Regards,
Erik

Hi Gregor,
thanks for your reference to your very good blog. I have read it and understood that I could write a model access class which build the URL including the correct account ID (i.e. object key) as filter value and then use this class to customize PCUI (i.e. tab or button).
But from the Business Package documentation (p.132) I thought that I could use a "standard" method to achieve BW report integration which requires a business partner ID at runtime. I.e. using the BW Report Wrapper iView (com.sap.pct.crm.bwreport.BWContainer) without writing code. Is my understanding correct?
So I tried to use the standard event ACC_FACT_SHEET and toolbar button FACTSHEET to navigate (object navigation) to my custom created page which included this BW Report Wrapper iView (custom).
My problem is to understand how the event is transferring the object key (by clicking the button 'Fact Sheet') so the BW Wrapper iView can generate the correct URL including the correct parameter 'filter_value'.
When I look into the Event definition of ACC_FACT_SHEET, I see that for 'Field->CRM Object ID' the value OBJECT_KEY is defined. However, the BW wrapper iView is not including the parameter 'filter_value'.
Can anyone tell me if my understanding of the BW Report Wrapper iView is correct, and how it is possible to transfer the object_key of the selected account to it?
Thanks and kind regards,
Erik
