Virtual Chars and Keyfiguers

Hi friends,
   how can we define virtual charecterstics and Virtual keyfigures.. in the info object creation screen there is no option to define that object as a Virtual.. then how can we define that object as virtual..
   and in what situation we can declare as virtual... can you plz give me a brief explination abt this... plz dont suggest any links... i did't got any conclusion by seeing those links..
    help ful answers will be highly appriciated...
regards
Babu

hi babu..
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 .(or)
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.
Virtual Characteristics and Virtual key figures are not part of data targets.
By Virtual Characteristics and Virtual key figures Query performance is going to impact.because these are not part of the data targets.
Ex: you have keyfigures profit,sales
You are going to create a Virtual key figures say COST = sales - profit.
so these cost is a Virtual key figures which is not part of a data target.
when you execute particular query your OLAP processor is going to pick the data by caluclating the COST.& it impacts the query performance.
You can get more information if you review the documentation for enhancement RSR00002.Go to SMOD type in RSR00002 and select the documentation radiobutton..

In SAP BW, values of key figures and characteristics do not necessarily have to be stored permanently in an InfoCube or in a master data attribute table. Virtual key figures and virtual characteristics allow the dynamic computation or derivation of values for key figures and characteristics at query execution time.
Examples 4 Virtual Characteristics
Dynamic categorization of key figure values such as age groups and price ranges, where the basis for calculating the categorical values is variable (as for the age).
2.Computation of complex compound values, combining information read from the InfoCube
with current information retrieved from other sources (e.g., master data attributes).
Virtual key figures can be used to perform complex computations on the fly that are
beyond the scope of the formulas available in the BEx Query Designer.
Examples include
1.Dynamic computation of the current age of a customer based on the current date and the birth date of the customer or the number of days on back order.
Both virtual key figures and virtual characteristics are rarely used, as they impact query performance and the degree of flexibility in defining aggregates significantly.
hope this helps..

Virtual Chars and KF

Hi Gurus,
can i use the Virtual Chars and KFs in an ODS
and then use them in the reporting and through codeing can i get them filled from the required value of an char or kf of the ODS only basing on a business logic.
If somebody can forward me the docs on them i will be happy or else any links of service.sap.com will also do please
thanks and regards
Neelu

Hi Neel
Virtual chars & KFs are just normal infoobjects. You add them to your provider without storing any information in there. Just leave them initial. The values for the virtual infoobjects will be derived during runtime of the query using the user exit of enhancement RSR00002. (go to SMOD transaction and take a look to the available documentation for RSR00002 enhancement).
Also Just have a look at the following threads

Virtual Char and Keyfigures in Queries

Hi Experts ,
I have one basic Keyfigure Constrained forecast (Fc)
for period X
and also I have one Field "Equal Numbers" (not present in cube)
If(FCx1=FCx2=FCx+3;u201DYu201D;u201DNu201D)
I have to compare the 3 respective period sales.....
the Equal number Field should be populated according to the above logic ....
"Equal Numbers" = 'Y' or 'N'
Fiscal year/period X (single,Mandatory) = 001.2007
X+1 = 002.2007
X+2 = 003.2007
X+3= 004.2007
How could I do this at Query level ?
and Pelase let me know if there is any alternative solution...for this.....
and one more thing ...
I have one more field "Minimum Sales per a month" in the selection criteria ... Which was not there in the Cube level... and the value for this is 1Metrci Tonn to infinite....
and also the field "Average coming 3 free periods "
I have whih should be restricted as below...
Average(FCx1;FCx2;FCx+3)u201D
Filter on >Minimum sales a month
How could I do the above those two at the Query level.....
In cube level I have only one basic KF Constrained forecast (Fc).....
is there any possiblity of Virtual Char/ KF .......
Could any body help me reg this...

Virtual char and keyfig

HI
wt is the ue of virtual chars an keyfiures.. how r they created.... how r they different from normal keyfig..... explain .. plzzzzzzz
<removed>

Rekha

Hi Rekha,
Virtual key figures: Will not be stored in the cube. Will be computed at run time when he query is executed. The are virtual in nature and not physical. When you view the cube's contents in listcube, you will not see it there. This is not the same as calc key figures. example: to store sales in your cube and this has o be allocated to all the group companies with a business logic, in this scenario you can code the logic in an exit and derive these virtual key figures. Another example is, when you report on no of days outstanding of your debtors. This will vary depending on when you the run the report. So, a exit can be coded to compute this run time. This is classical example of virtual key figure.
Virtual characteristics: Same as above. Here you will derive the characteristics while report is run.
Depending on the requirements, you must decide when to code for a virtual kf or cha and when to store them in the cube physically.
Virtual characteristics and Key figures are useful if you want to dynamically pouplate data from the fact table to the field.
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
Check "how to" doc for virtual characteristic/key figure details.

Virtual key figures and charecteristcs are populated at query execution time.
These virtual objects should be included in the modelling level itself,so that it can be used in the query while using exit in that.

Virtual chars and keyfigures

HI All,
I have created a BADI for virtual characteristics and key figures according to a business requirement but the biggest problem is the query performance. Its taking around 15 to 20 minutes to refresh a query. I have used internal tables and field symbols in the BADI but I do not know what is causing this problem.
Could anybody suggest me? How to improve the query performance? Do I need to do any changes in the code? or anything that can be done in query level? Or taking off virtual characteristics and key figures or do physical design instead of virtual characteristics and key figures? I have done all level of query performance tuning but still same problem.
have done all kinds of analysis but still I could not find the solution.
I know this is defiantly something to be done with virtual characteristics and Keyfigures.
Is there anything new that I can do tuning for code?
Points will be assigned.
Thanks,
Martin.

dear all,
I implemented badi for virtual key figures , i am unable to stop at compute method.
could any one of you suggest me why it is not stoping at compute method while executing quesry even though i kept break points.

Virtual Char and KF

Hi Friends,
Thanks for your inputs.. I need more info on this. Let me give you you my exact requirement. I have MTD Actaul and MTD Target Calculated KF. and MTD Status is also a KF which has the logic mentioned below to display the values 'Achieved', 'On the target', 'Almost on the target', and 'Behind the Target'.
( 'MTD Actual' > 'MTD Target' ) * 1 + ( 'MTD Actual' < 'MTD Target' ) * 4 + ( ( ( 0.975 * 'MTD Target' ) < 'MTD Actual' ) < 'MTD Target' ) * 2 + ( ( ( 0.90 * 'MTD Target' ) < 'MTD Actual' ) < ( 0.975 * 'MTD Target' ) ) * 3
How will I display Status of values 1, 2, 3 and 4 which appears in the above logic. Client requirement is to display text with one Status column depending on the Status Values.
Kindly help me.
Regards
Prasad

Hi Ajay
Thanks. you have cleared my doubt. Even I feel it may not be possible to display text status. Now I have CKF whose numeric values( 1, 2,3,4), and Characteristic I/o ZPSTATUS with the master data as (1,2,3,4 and respective status Texts) whose value is not filled by update rule.
Now to capture the values from CKF to ZPSTATUS What I have to do? Is there any code Ihave to write. Can you give me sapme of that CODE.
It is of great help.

Prasad

Virtual Key Figs and Virtual Chars......Perf

Hi,
Can anybody please brief me on Performance Factor will it increase or decrease when you use virtual chars and virtual key figures?
Thanks,
JB

Hi,
Perofrmance decreases with the use of virtual key figures and chars as the values of the objects are calculated at the runtime of the query.
It affects worse if the amount of data thast is going for query processing is huge.
Since using VKF is like calculating at the runtime of the queires by applying the logic needed.
It is only reccomended in the case when the users are having no issue with the performance of the queries and are ready to wait for the output.
Go for it when you have no other option.
Hope it helps
Thanks

Virtual Char error - UC_OBJECTS_NOT_CONVERTIBLE

I posted this on BI general, but thought may be this is a better place..please respond..
Hi all, I am trying to implement a virtual char and I foolowed the how to paper from SAP...My example is a very simple one where I want to test how this concept works. What I wanted to do is to be able to assign a constnt value to the characteristic 0PLANT, but I get the following runtime error when I test the report in RSRT.
UC_OBJECTS_NOT_CONVERTIBLE - Data objects in Unicode programs cannot be converted.
The statement
"MOVE src TO dst"
requires that the operands "dst" and "src" are convertible.
Since this statement is in a Unicode program, the special conversion
rules for Unicode programs apply.
In this case, these rules were violated.
here is the code I had in the method: IF_EX_RSR_OLAP_BADI~COMPUTE
method IF_EX_RSR_OLAP_BADI~COMPUTE.
field-symbols <fs_0material> type any.
field-symbols <fs_0plant> type any.
data: l_plant type /BI0/OIPLANT.
assign component p_cha_0material of structure c_s_data to <fs_0material>.
assign component p_cha_0plant of structure c_s_data to <fs_0plant>.
<fs_0plant> = l_plant.
endmethod.
I tried to search in SDN and on Service market place but could not find proper documents. Can someone help?

Ok I am past the error message and can actually execute it throught RSRT, but I dont see the virtual chars being filled in the output result. I can see through debug mode that the Virtual char in this case ZMRPDATE getting a value and also c_s_data being filled with that value, but finally when it outputs the result in RSRT it shows nothing. Is there any step that I am missing??
METHOD IF_EX_RSR_OLAP_BADI~COMPUTE .
field-symbols <fs_zmrpdate> type any.
field-symbols <fs_0material> type any.
field-symbols <fs_0plant> type any.
field-symbols <fs_zberw2> type any.
data: l_plant(4) type c.
      l_plant = 'ABCD'.
if p_cha_0plant is not initial.
assign component p_cha_0material of structure c_s_data to <fs_0material>.
assign component p_cha_0plant of structure c_s_data to <fs_0plant>.
assign component p_cha_zmrpdate of structure c_s_data to <fs_zmrpdate>.
assign component p_kyf_zberw2 of structure c_s_data to <fs_zberw2>.
endif.
select single /bic/zmrpdate from /bic/azpur_mdp00 into (<fs_zmrpdate>)
           where
                material = <fs_0material> and
                plant    = <fs_0plant>.
<fs_0plant> = l_plant.
<fs_0material> = l_plant.
******<fs_zmrpdate> = sy-datum.
<fs_zberw2> = '999'.
Write afte the above step I could see that the C_S_DATA has changed, but the output result in RSRT will not the fields filled, they are still blank!!!!!!!!!!!!!!!!

Urgent!!Virtual Char & KF using customer exit!!

Hi
Anyone explain me in easier way the steps for Virtual char & KF & where we use it??H to use it with the help of customer exit & why??
Pls xplain me .
thnx
raj.

Hi,
A virtual characteristic / key figure can be used to derive values at
query run time
The virtual characteristic / key figure must be added to the cube as a
characteristic or key figure but not filled in update rules or transfer
rules
Useful for determining values that are not known or determined until
query runtime
You will find the Doumentation and Example in SMOD for Virtual Characterstics and Keyfigures.

Virtual chars/key figs

Hi BW gurus--
Let me know the Purpose of Virtual chars and key figs.
also how to handle and how to create the same.
Regards,
Rambo.

Hi Rambo,
virual chars/key figs are normally created infoobjects. They will be added to a provider, but there is no value posted to them in the provider. They will stay initial. In the relevant user exit (enhancement rsr000001) you have to implement the coding to populate the values during runtime of your query.
You can use them
a) to show movements without having any data posted to your provider (e.g. you can set a flag identifying a sales order for 'in time', 'due' or 'late' if you compare the run date of the query with the desired delivery date of the customer. Of course for order without having the status 'delivered'.)
b) to create flexible classifications (e.g. sales orders amounts: 0 - 100 = class A, 101 - 1000 = class B.... if you want to change the classification based on the amounts you have to use virtual infoobjects)
Hope this helps!

Virtual Char to fetch Navigational Attr of a Navigational Attr

Hi,
As per the Data volume I can delete data from my cube to include a Transitive Attribute to get the Navigational Attribute of a Navigational Attribute Information in Report.
Other option I am considering is Virtual Charu2026.can any one please update me with the logic that I need to use.
0CUST_SALES --> 0CUST_SALES__0PLANT --> 0PLANT__0PLANTCAT
0CUST_SALES__0PLANT is a Nav Attribute of 0CUST_SALES
0PLANT__0PLANTCAT is a Nav Attribute of 0PLANT
In my cube I had 0CUST_SALES and 0CUST_SALES__0PLANT information available and my requirement is to have a Virtual Char similar to 0PLANTCAT which have to populated at query runu2026
Thanks

right click on the particular infoobject and say change (do it in sand box first please and get you supervisor approval because it is a lot of work to do). Know check the navigational arritbute flag, acitvate it. but please note that it will change in all the queries whereever this infoobject is used. Can anybody eloborate this process in detail step by step.
Sharat.
