Problems with creating badi implementation for virtual key figures

Hi,
I'm running BI 7.0 (unicode).
I have been trying to follow this blog to calculate the virtual keyfigure in my infoset - Using Virtual Key Figure and Characteris in an InfoSet
My infoset includes 1 infocube, and 3 master data infoobjects. I have created everything the blog was referring to, and activated fine. However, it seems that when the field symbols are assigned from the c_s_data structure, they do not get referenced correctly, so that no correct memory area is assigned and instead the whole c_s_data structure is assigned to the field symbol, which prevents me from referencing the right mem area correctly.
For example, in this statement
ASSIGN COMPONENT P_CHA_ZMYINFOSET___F120 OF STRUCTURE c_s_data
TO <fs_ZMYINFOSET___F120>.
the component p_cha_zmyinfoset___F120 of c_s_data supposed to be assigned to the field symbol (point to the correct place in structure c_s_data). In other words when this statement is executed, the program looks at structure c_s_data, finds the component zmyinfoset___F120 in it, and assignes the position of that component in the structure to the field symbol, so that it could be referenced in the code. However, the correct assignment does not happen.
When I debug the code and view the structure c_s_data, I can never find any component with any of the names I can find in my BEX query like ZMYINFOSET___F120. All I see are the components that are named like these: Z____5179 (C_S_DATA-Z____5179), C_S_DATA-S____5150, etc. I see the correct values, but components all have weired names like that. I thought in Infosets the components are named in the following fashion: INFOSETNAME___FXXX which you can see from your BEX query designer. Why is this happening? Why don't I see the correct names in the c_s_data structure? If instead I try to assign those components with their weired names directly, I still get incorrect assignment.
what am I doing wrong?
I was reading abap help on this statement: assign COMPONENT comp OF STRUCTURE struc
and the following I found:
With this expression for mem_area, the memory area of a component comp of a structure struc is assigned to the field symbol. While the structure struc is specified directly, a data object must be specified for comp. The evaluation depends on the data type of comp:
If the field comp has a non-text, elementary type, the content is converted to the type i and interpreted as a position of the component in the structure. if the value for comp is 0, the storage area of the entire structure is assigned to the field symbol.
From what it says above, my value for comp is always 0, so that the entire structure is always assigned to my field symbol instead of a specific position in that structure.
please let me know what is wrong here.
thanks.

Create Badi for Virtual Key Figure

Hi experts,
i have to create badi for virtual key figure in BIW for dat i m creating Badi in BI development but its asking for Access Key.
Badi name is RSR_OLAP_BADI
i want to know while creating classic Badi with Implementation Name do developer need access key or thr any othr way to develop Badi for Virtual Key Figure.
Tell me for creating virtual key figure in biw we use Badi and for dat we have to create the Badi in BIW Dev. or in R/3 Dev.
it first time dat i m creating BAdi.

Do we write variable customer exits for virtual key figures in Bex?

Hi all,
Am I thinking the right here " We write variable customer exits in CMOD for virtual key figures in BEx " or am I totally wrong. If thats the case where do we write it.
Thanks,

Type conflict with ASSIGN in BADI for Virtual Key Figures

We get the below error dump in ST22 when executing BEx queries that contain virtual key figures.
error message - 'Type conflict with ASSIGN in
program "ZCL_IM_THR_RSR_OLAP_BADI======CP".'
We have a BADI implementation that calculates few virtual key figures included in some infocubes & multiproviders. The error would arise if we execute two queries (containing common Virtual Key figures) one after the other without closing the first query.
We found a note "Note 1237689 - Virtual chars. and key figures in input-ready querys" that could be relevant to our issue and wanted to apply this note but unfortunately the note is only applicable to SAPKW70016 to SAPKW70018 and we are support pack 15.
Can you please advise what the problem could be/suggest corrections for the same.

Hi Kulmohan,
Did you fix your issue? We are facing the same issue. Could you please let me know if you have any solution for this issue,

Problem in creating new implementation for filter dependent badi

Hi Experts,
I want to use badi NOTIF_EVENT_POST.It is a filter dependent badi. It is asking filter type while implementing thro se19. Could anyone pls tel me how to create new implementation for the filter dependent badi. Existing filter type is QMART. is there any problem if i change the filter type?
Thanks in Advance!

Hi ,
NOTIF_EVENT_POST is filter dependent and filter values are based on QMART value in table TQ80. You need to specify the filter value ie : QMART value before implimentation , before that check all active implimentations for the same , if u have to impliment on same filter value , you need to deactivate the one which is implimented on same filter value .
You are not supposed to change the filter type.

Is this a candidate for virtual key figure ?

Hello BW Experts,
discount amount = sale amount * disc rate
discount amount is only for the analysis purposes, sale amount comes from the billing document, disc rate is manually maintained in a custom r/3 table (brought to BW as ODS).
Disc rate can change daily. In the Bex report discount amount should be calculated based on the month end disc rate.
wondering different methods to achive the same:
1) make the discount amount as the virtual kf and lookup the month end rate from disc rate ods
2) is it possible to declare the disc amount as the keyfigure with some sort of aggregation / cumulation ?
any suggestions appreciated..
Thanks,
BWer

Hello,
Option 1 is simple and more practical where as option 2 falls under the category of non-cumulative key figures, which is slightly complex to handle.
Option 2 also depends on number of entries in the Info cube, if the data in the Info cube is not huge then 2nd option won't cause any performance issues.
You can also look at other option of creating Global calculated key figures with exception aggregation "Last value" but for this, you need to include discount rate a part of the Info cube.
Hope this helps.

Problem with the behaviour of input ready key figure

Dear All,
I am using one input ready key figure in a globally reusable key figure structure for my planning layout. When the input ready query is executed as such, the i/p ready key figure is readily available for inputting any data (as expected), but the moment the global reference from the key figure structure is removed in the query designer (from the context menu - > Remove Reference), that i/p ready key figure structure turns out to be non input ready and hence no entering of data is then possible.
I am removing the reference from the structure for some other editing purpose but the above mentioned problem comes in between.
The only input that i can provide is that this i/p ready key figure utilizes two hidden inverse formulas, but eventhough things are fine when the reference is not removed.

Hello Durgesh,
I suspect this to be a bug. Please open a customer message so SAP support can analyze the issue (include technical names of the original query with global structure and your new query where the reference was removed; put it on component BW-PLA-IP-QD).

Marc

Problem with creating Edit page for employees , based on otn tutorial

Hi
Thank you for reading my post
I used one of oracle tutorial and create a jsf page which contain a for for departments
and a table for employeed ( I used visual and declarative development with oracle jdeveloper)
Now i want to add an edit page to my jsf project which allow me to edit an employee
to do this : I add a jsf page , I add editing form (the edit form work well , I mean which i change the data and press submit it change the data in database)
now the problem is that i want to link this two page
in a manner that when user select an employee from table and pressed edit button ,
it shows edit page with that employee as "under edit" employee
here is the link that i used to learn this stuff.
http://www.oracle.com/technology/products/jdev/viewlets/1013/jdev_overview_xp_viewlet_swf.html
Thanks

Basically you create a JSF Page Navigation diagram and drag on you customerList page and your Edit Customer page. Add an "arrow" to link the two pages and name this arrow EDIT.
Then drop a button onto the CustomerList page and the ACTION property will not have a drop down list and you select EDIT (which is the name of the arrow you created).
Simple steps available using the workshop on the right hand side of the page

J2me Gaming : Problem with Creating build(jar) for nokia phones

Hi,
I am having trouble in making a package (jar) for nokia phones. I have been tring using J2ME wireless kit, Eclipse, Nokia development Suite and IBM Device developer but havent been able to make a perfect package out of it.
I have even downloaded the plugins for Eclips but not able to configure it properly. I did every thing according to the specifications. but while building project i get the error "Problem while running the build script ....." .
Overall i want create a jar package and obufuscate that for Nokia phones.Its real urgent. Wud want someone to guide me on all the necessary.
Thanks in advance.

Hi,
yeah I can recommend - get Sun ONE Studio 5, Mobile Edition (http://wwws.sun.com/software/sundev/jde/studio_me/early_access.html). That's pretty much about it (obfuscation included, .JAR file creation in no-time).

Passing two variables to BADI implementation for virtual chars

I have a BADI that fills a virtual characteristic. This BADI gets a date variable value from the query. Can I send another variable value to the BADI? I want to add another retriction based on the state. If I don't add this restriction to the BADI, it will go thru all the records in the cube and make it slow. How can I do this?

Hi there.. if that state field is available in the badi you can use that field.. check the attributes in the BADI if that field is a part of any table or is that an importing parameter..
if <table>-<state> = 'US'.
proceed ahead..
endif.

Creating BADI for Virtual Key fig: Error: RSR_OLAP_BADI does not exist

Hi,
I am following some instructions to test the implementation of virtual key figure and came to the point to create the BADI.
Intructions on page 5:
https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/e051fda8-71a9-2a10-ac9e-8d17414a8c8c
SE19
Create Implementation; New BADI; Enhancement Spot: RSR_OLAP_BADI
At this point I get an error that RSR_OLAP_BADI does not exist.
I then chose at random APB_LAUNCHPAD but this works in the sense that it took me to the next screen
1. What does it mean by RSR_OLAP_BADI not existing?
2. I know the instructions points to choose RSR_OLAP_BADI, but why that particular program and how does one gets to know that it is the one to use for virtual key figure/char implementation?
3. When I tested with APB_LAUNCHPAD, I did not get the same screen on page 5 of the link, is it different for BI 7? Or, am I missing a point?
Thanks

Hi,
thanks for the guidance.
Yes, I tried to implement exactly as in the article.
Yes, I defined the filter for the Infoprovider, as ZV*
Are you suggesting that at this point, if in the method if_ex_rsr_olap_badi~define, I change the value of
"ZV_ZIPER" to my DSO or Cube, I should now see the virtual key figure in my query?
Based on this understanding, I modified the method as follows, (my cube name is 2LIS_11_VASCL):
method IF_EX_RSR_OLAP_BADI~DEFINE.
DATA: l_s_chanm TYPE rrke_s_chanm,
l_kyfnm TYPE rsd_kyfnm.
FIELD-SYMBOLS:
<l_s_chanm> TYPE rrke_s_chanm.
Insert Code
CASE i_s_rkb1d-infocube.
CASE i_s_rkb1d-2LIS_11_VASCL.
 WHEN '2LIS_11_VASCL'.
 l_s_chanm-chanm = 'ZVAR_SHPR'.
 l_s_chanm-mode = rrke_c_mode-read.
 APPEND l_s_chanm TO c_t_chanm.
 l_s_chanm-chanm = 'ZVARDT'.
 l_s_chanm-mode = rrke_c_mode-read.
 APPEND l_s_chanm TO c_t_chanm.
 APPEND 'ZV_20DV' TO c_t_kyfnm.
ENDCASE.
endmethod. "if_ex_rsr_olap_badi~define
After activation, I checked the query and still I am not seeing the virtual key figure in the query for selection.
Any more ideas?
Thanks

Virtual key figure BADI - does not change value

I wrote a badi for virtual key figure according to guidelines from an SDN doc on how to create virtual chars and kf's.
However, the value of the key figure is not changed at all. Below is my code. Please see what I'm doing wrong
method IF_EX_RSR_OLAP_BADI~DEFINE.
 APPEND 'ZRANKS' TO c_t_kyfnm.
endmethod.
method IF_EX_RSR_OLAP_BADI~COMPUTE.
if P_KYF_ZRANKS > 0.
 assign component p_kyf_zranks of structure c_s_data
 to <fs_ranks>.
 <fs_ranks> = '1.0'.
endif.
endmethod.

There is something you need to do which I have not seen described in any of the documention here.
You need to copy the source code for the INITIALIZE method directly from the code given in the example class CL_EXM_IM_RSR_OLAP_BAPI. That is where the P_KYF<object> and P_CHA<object> attributes are assigned their values. If you do not copy this code into your own implementation, these attributes have no value in the COMPUTE method and your code will probably not work.

BW : Virtual key figures

Hii experts ,
What are virtual key figures .
Plz explain .
Thanks & regards ,
Madhavi S Bichakal

Dear Madhavi,
Virtual Key figure
virtual key figures are key figures within an InfoProvider that are not filled with data. Instead the key figure value is determined at runtime of the query using custom ABAP coding .
this keyfigure is not populated with the data by using update rules. but this virtual keyfigures will detemine the value only at the runtime of the query.
nomally when we store the key figure value in the cube as we do it for a normnal keyfigure it gives us the fact(Fixed truth ) information but by using virtual keyfigures we can show the present truth in the report.
for example :- let say we have a transaction on 01/01/2007 for material M100 @ price of 100 and on 02/01/2007 the price of material M100 has changed to 200.
when we store price as a normal keyfigure in the cube it will give fact i.e, 100
but if we design the price as a virtual keyfigure it will give out present truth as 200.
Virtual characteristics and Key figures are useful if you want to dynamically pouplate data from the fact table to the field which doesn't have any data in the fact table and also used to build an internal security model before the data gets passed to DATA_PROVIDER.
You can get more information if you review the documentation for enhancement RSR00002.Go to SMOD type in RSR00002 and select the documentation radiobutton..

Virtual Key Figures - How are they triggered?

HI,
I am trying to implement the Virtual Key Figure user-exit. I have created all the necessary coding and activated the user-exit.
My cube contains data but the VKF in question has not been populated with any data because I have set the update rules to "NO UPDATE", so the VKF is completly empty.
I've defined my query to use the VKF, but when I execute it, the user-exit is not triggered.
How does BW determine if a query should call the user-exit? I though it was to do with creating the variables in ZXRSTOP in line with the cube/kf name as I have done (DATA: g_pos_0IC_C03_zfcstwk TYPE i.).

hi Peter,
try to check with RSRT, put in your query technical name,
and click 'technical information', check info on 'virtual char/keyfigures', it should have 'Y' and a list of virtual char/kf. and also check 'execute+debug', mark checkbox 'display sql', after that check the sql statement if your virtual kf is in select statement.
try in RSRT menu 'environment'->delete old abaps.
if you want the virtual kf only run for certain query,
you can restrict in ZXRSRZZZ, using
if I_S_RKB1D-compid = 'your query technical name'.
... your logic for virtual kf ...
endif.
hope this helps.
