DSO Activation failed possible errors


DSO Activation Failed Errors in SAP BI


Most of the cases we will face below errors in DSO Activation.
1) Activation of M records from Data Store object terminated.
    i) SQL Error while reading table in database.
    ii) No batch process available. Process terminated

2) Request not exist in DSO and DSO is inconsistent. You will get request number.

Now we will see the solutions for the above issue.

1) i) : a) Right click on your DSO in RSA1 and click on manage.Please check if you have any red request in request tab of DSO.
In request tab below, you will find option "Request Display: Date of Update From" change this date to one or two months back and click on refresh. you will get the old request now, now check if you have any red request.
b) If you find any red request, click on monitor tab and make the technical status to red. Now come back and make the request status red in request tab of DSO.Delete the request from request tab.
c) Activate the DSO now, it will get successful.

1) ii) : You will get this error, if you don't have enough background processes in your server.

a) check number of background processes maintained by going into tcode RSODSO_SETTINGS.
Please follow the below steps to rectify this error.
a) go to manage tab of DSO. now go to request tab and select the request and click on activate.
b) In the next screen select the request you want to activate.
c) Now click on parallel activation
  
d) In the next screen, you will get the no of parallel processes maintained for DSO activation. Make this to 1 and save it.(By default we will have 3)
e) Now click on activate, this time your DSO will get activate successfully.
for more details you can refer below thread as well.
 2) : You will get this error if someone is wrongly deleted the request from manage of DSO. wrongly means properly making the request red and deleting from manage tab. If request is deleted from manage tab but still present in back end tables then you will get this error.
The request loaded to the DSO will be stored in the following back end tables.
RSICCONT, RSMONICDP, RSODSACTUPDTYPE and RSODSACTREQ.
If we have any discrepancy between these four tables, we will get the above error.
Apart from this error we will get the request number in error log. We need to delete that request number from these four tables if it exist.
please check the note 868391 for details.

Hope this will be useful...

SAP BI BO Questions Corner(Question of the day)

Hi 

Welcome to question of day for SAPBI  BO with simple Answer

Q.14 In which scenarios u have used ABAP (ABAP team)?
Ans Basically we can use ABAP Code in multiple scenarios while we are implementing BI project
Here some scenarios I have in used in my recent project
As you know in SAP BI 7.0 Four types routines are supported like
  1.)Characterstic routine
2.) Start Routine
3.) end routine
4.) Expert routine
Characteristic routine: Is for simple routine used in project for calculation purpose at transformation level
Example you have 3 info object a.) cost price b.)net price c.) profit
You have to calculate profit info object value (formula: net price- cost price)based on other infoobjects(cost price and net price)
In this scenarios we can use is characteristic routine This can be done at report level also by using calculated key figure or formula.
The difference between Start routine and end routine is start routine perform its operation before trasformations(befor data loading ) end routine performs its operation after transformation(after data loading )
Scenarios for these start routine and end routines are


Start routine you can use in the scenario of while you want to load based on one condition like if sales > 1000 then only load otherwise no for this scenario we can use this routine
End routine we can use in situation we want to delete the records with zero sales value in this case we can use End routine(performs it operation after transformation)


Expert routine is totally different which will use in case of while our transformation not helping. In this case we can go for expert routine .Delete all our transformation and create the expert routine 
Need perfect scenario for Expert routine Click Here


For all types routines document Click here


And also we can use these abap in customer exit at reporting level


Scenarios for customer exit if suppose you want to pop up current month and year in variable(default value) then in this case you can use customer exit
Actually here istep functions we are using to generate the current the current month in customer exit
they are four types of isteps function available
istep0,istep1,istep2,istep3
istep0 is for authorization check
istep1 is for populating  default value (before variable pop up it operates)(current month)
istep2 is for generation previous month based on current mont or user input(operates after variable popup)
istep3 is validation check and to recall (not sure)

Q.13 What is aggregate awareness in SAP BO?
Ans Aggregate awareness is one type of option used in universe for improving the performance of query while retrieving data
Example you have Objects like below in three table
Table 1  year
Year
Sales
Quantity sold
Year
Qtr
Month
Sales
Quantity sold

Year
Qtr
Sales
Quantity sold




                                                                                       
                                                                                                                   

Tab1 (year)                 Tab2(year_qtr)            Tab3(year_qtr_mnt)
If you fire a query on year and sales then query don’t where to fetch the data because year object is available in three table
For this purpose we have to written the aggregate awareness function for objects in universe
Aggregate awareness for year object is
Rt click on year objectàin where section write like
@agregate_awareness(year.year,year_qtr.year,year_qtr_mnt.year)
Syntax:@agregate_awareness(table1.column,table2.column,table3,column…….)
Here table 1 is high priority and table n(last table) is low priority for query to redirect
So if you select year and sales in query the query easily goes to tab1(year) because as per aggregate awareness you have year tab1 has high preference so it directly goes to tab1
Like this you have to write aggregate awareness for all objects
For qtr
@agregate_awareness(year_qtr.qtr,year_qtr_mnt.qtr)
For month
@aggregate awareness(year_qtr_mnt.mnt)
Suppose if you mnt qtr sales objects are using in you query ,Query will directly goes to tab3 because mnt is available in tab3 only and also as per aggregate awareness function qtr ,mnt available in tab3 only
We can write this aggregate awareness function for measure objects also
Syntax @aggregate_awareness(sum(table1.column),sum(table2.column),sum(table3.column)……)
For sale
@aggregate_awareness(sum(year.sales),sum(year_qtr.sales),sum(year_qtr_mnt.sales))
qtr,mnt object are not available in tab1(year) so we have to do aggregate navigation for this
Goto toolsàaggregate navigationàselect tab1(year) rt side all object will get disply
Check for qtr,mnt for this tab1(year)
Like this we have do same aggregate navigation function for mnt also in tab2(year_qtr) because mnt is also not available in tab2(year_qtr)
Some go to toolsà aggregate navigationà select tab2(year_qtr) rt side check for mnt
If you do this aggregate navigation for those objects(mnt),if query using the same object(mnt) then query will not redirect to tab2,tab1 because we did aggregate_navigation for Query will directly go to tab3 in which mnt object is available and as per aggregate awareness for mnt it is tab3
Ex:1 query contains year,mnt sales then query will directly redirect to tab3
Ex:2 query contain qtr,quantity sold then query will directly redirect to tab2
Ex:3 query contain year,qtr,sales then query will directly redirect to tab2
All these above 3 example queries retrieving data as per aggregate awareness and aggregate navigation.

Q.12 What is line item dimension in SAP BI?
ANS When we have size of dimension table greater than 20%(SAP Recommendation) of fact table then we should make that dimension table as line item dimension
How to know the dimension table size have more than 20% of fact table:
Using table: SAP _INFOCUBE_DESIGNS
There you will get all the cubes and their dimension table size So you can easily find which does have high size
Use: By making dimension table as line item dimension then no dimension table is created for that particular table, SID will take the role of dimensions table.
Improve the performance by creating SQL quires at database level instead of at BI side to retrieve data (when you fire a query)
Disadvantage: No possibility of add new characteristic to dimension table

03/June/2012
Q.11 We have RKF in BEX that is global for local what is the option?
ANS For local we have option called SELECTION(rt click in rows/columns --> SELECTION)
02/June/2012
Q.10 If you fire a query  on info cube at first to which table that query will redirect? to fact table or dimension table?
ANS Obviously to Dimension table because Dimension table consists of characteristics while fact table consists of key figure,Initially query checks for characteristics and then go to fact table for key figures (making calculations here) 
01/June/2012
Q.9 what is the table nams of write optimized DSO?
ANS Actually write optimized DSO consists of only one table which store active data there is no specific name for this table,And also the data in this table available for Reporting,
One thing here in Write optimized DSO  no SID are created at time of data loading SID will get generate at time of reporting,It results poor performance.
And also maintain semantic key for data uniqueness,if you perform check on data uniqueness option at DSO properties level 
31/May/2012
Q.8 Types of DSO's available in SAP BI 7.X?
ANS There are 3 types of DSO's available in SAP BI 7.X
1.Standard DSO : which contains three table a.) Activation queue table(New data table)
                                                                    b.)Active data table
                                                                    c.) Change log table
When ever you load the data initially it get store in New data table,Data in this table not available for reporting
After activation only data move to Active data tale,and data is available for reporting
2.Write optimized DSO: Which contains single table .Data loaded directly to this table no activation need
This is used for when you large set of data use this WDSO before data loading in to cube,standard dso for testing purpose 
3.) Direct update DSO: For this no transformation required to load data,which is updated direclty by function module,from datasource.
30/May/2012
Q.7 What is KPI?
ANS KPI means Key performance indication in business organization which show the performance of particular division in organization,
Example : Total work force is one type KPI related HR division in organization which show the employees and their details 
29/May/2012
Q.6 What is compounding of info object in SAP BI? Explain briefly?



ANS Suppose you have two info object like ZSTORE and ZCITY
ZSTORE infoobject have values like S1,S2,S3(Store1,store2,store3)
ZCITY infobject have values like Bangalore,Hyderabad,Delhi
Hyderabad has stores s1,s2,s3 ,Bangalore has stores s1,s2……etc
Zstore infoobject definition in incomple with out object zcity
If you use ZSTORE to show sales  in you query no use with that infoobject your results like might be
S1        100
S2         300
S3         890
By this you do not know  the store1, 2,3 belongs to which city.
So here definition of info object (ZSTORE) is incomplete with out compound info object (ZCITY)
We need to add compound info object (ZCITY) to info object(ZSTORE) in compounding tab  info  object(ZSTORE) level
What happened after adding ?
Once you add the compound object to info object ,when ever you add the object(ZSTORE) to info providers automatically it compound object zcity also got added to your info provider
Now if you use this object (zstore) in query zcity object also added automatically because it is compounding info object the results looks like
Zcity/zstore     sales
Bangalore/s1     499
Bangalore/s2     435
Hyderabad/s1   458
Hyderabad/s2    599
S this is meaning full query For this we have to add the compounding info object

Q.5 What are types of info objects available in SAP BI?
ANS. They are five types of info objects available in SAP BI ,
1. Characteristics, 
2. Key figures 
3.Unit Characteristics, 
4. Time Characteristics 
5.Technical Characteristics
27/May/2012
Q.4 What is tcode used to allow special characters in SAP BW system?
 ANS. T-code:RSKC
26/May/2012
Q.3 What are the traps in SAP BO ? What are the steps to solve traps?
ANS. Generally,In SAP BO we might face 2 types of traps while construction universe on relational database.
They are one Fan trap and second one is Chasm trap
Fan trap occurs when two tables have join 1 to n happens two times simultaneously(Ex:1-->n,1--.n) the we face a fan trap.This can be solved by using alias for last table 
Chasm trap occurs when two fact tables connect with single dimension table the Chasm trap occur This can be solved by making context for these fact tables
25/May/2012
Q.2 what is the tool used to transport the universe from dev to prod?
ANS. In SAP BO 3.1 XI R3 it is import wizard the transportation procedure changed in SAP BO 4.0 with LCM(Life cycle management tool) 
24/May/2012.
Q.1 What is SAP BI?
ANS:SAP Business intelligence is a approach to integrate the data from different datasources into single data source to make reports for organization help in decision making for their organization by management.
