Manage query - run time errors

Hi,
we have one user working at one desktop which receives error "run-time error 5" followed by "401 Automation error" when selecting the manage query wizard proceeding from the BPC Excel action pane.
We only have this at one desktop. Any ideas?
Dries

Hi,
You can check the query run time by using T code RSRT.
1. Go to T code RSRT
2. Give your query name.
3. Click on the "Execute + Debug" tab
4. Various check boxed for Debug options will appear on the screen
5. Under the "Others" node you will find the check box for "Display Statics Data"
6. Check this check box and click on continue.
7. This will execute the query and provide you selection screen if any.
8. Once the query is completely executed, click on "back" button or simply hit F3.
9. This takes you to the "Statistic Data for Query Runtime screen"
10. Here you can take the total of "Duration" column to get the total duration for query execution.
Please refer following link for details:

BI Statistic and Techincal Content

I am a bit confuse with the relationship between BI Statistic and Technical Content in BI7. Can you please confirm my understanding below:
1) In BI 7, in order to record the BI Statistic, we MUST turn on the Query, InfoProvider etc via transaction code RSDDSTAT.
2) Once this is done, system will record the statistic of that Query/InfoProvider data automatically.
Turning on the BI Statistic means nothing if we didn't didn't carry the following right? I mean we can build query to report the statistic data, correct?
3)     In order to display this statistic data via transaction code ST03, we MUST turn on the Technical Content.
4)     Schedule the Process Chain and load the data from the statistic table into Technical Content.
5)     Once this is done, we can display the statistic data via transaction code ST03.
6)     Because we have loaded the statistic data into Technical Content, then we can delete the old statistic data.
7)      Now we can build Query on top of this Techincal Content and report the Statistic data, correct?

Hi Iynn,
Your understanding is correct. for number 6) "Because we have loaded the statistic data into Technical Content, then we can delete the old statistic data ", you don't have to delete the data manually as it will be done automatically every 14 days if your system is lower than SP16 (it's now 30 days with SP16 and above). If you want to change this behavior, you can use program SAP_RSADMIN_MAINTAIN to create entry TCT_KEEP_OLAP_DM_DATA_N_DAYS in RSADMIN table with the value you desire. More info in notes 891740, 1095411.

Virtual IP - how to speed up query result?

Hello,
I have a virtual IP. When I execute a report I receive after 5 minutes a result.
Following questions:
1. How can I detect the bottleneck?
2. Is there a "standard" way to improve the query runtime?
Thanks for input.
Best regards.
Pascal Kern

Hi, STARWARS
Use tr RSRT -> Execute + Debub -> Mark "Display statistics data" -> Execute
Press F3 (back).
There you can see "Statistic Data for Query Runtime".
Analyze lines with long duration.
Hope it helps,

Difference between BBP_GET_STATUS_2 and CLEAN_REQREQ_UP reports

Could someone explain in simple way what is the difference between BBP_GET_STATUS_2 and CLEAN_REQREQ_UP reports? I have read the differences in standard documentation but it is a little confusing.
Thanks!
Regards,
Madhur

Hi
CLEAN_REQREQ_UP (Cleaner Job)
You can use this function for document types Shopping cart, (Local) Purchase Order, Confirmation, and Invoice to trigger a synchronization with the associated documents in the back-end system. The system checks whether and how the (follow-on) documents were posted in the back end, and updates the object link and references, as well as the document status.
A job (background processing) is generated for the program CLEAN_REQREQ_UP. When this is run, the system queries a database table containing the transfer information of the documents to the back end. The entries are checked with the data of the respective back-end systems. If the back-end transfer is successful, the respective entries are deleted and the prerequisites for further processing are created.
BBP_GET_STATUS2 (Status Job)
The status job was created by SAP to update the EBP system with data such as purchase requisition number, purchase order number, goods received or invoices recorded manually in R/3, etc. The report should not be run on a frequent basis at short intervals unless the order count from EBP to R/3 is not that high. Otherwise, a recommended interval for running the report is approximately every hour. Basically the schedule times depend on your business requirements.
Until this job runs, the user will not see the number of the backend document created in R/3 for a particular shopping cart in the history tab of the check status transaction.
Some more information :
Go to:
SPRO->IMG->Integration with Other SAP components->Advanced Planning and
Optimization->basic Settings for the Data Transfer->Change Transfer->
change Transfer for Transaction Data->Active Online Transfer using BTE
Here you should maintain the application 'SRMNTY' with active flag.
Once this customizing is enabled, whenever a follow-on document
(either confirmation or invoice) for an extended classic PO is created
in the backend R/3 system, the R/3 system communicates to the SRM system
by creating an entry in the table BBP_DOCUMENT_TAB for this PO.
The item level of the SRM PO has fields to store the actual quantity
and values entered for the corresponding confirmations and invoices.
After that, run the reports CLEAN_REQREQ_UP and BBP_GET_STATUS_2.
When the report CLEAN_REQREQ_UP runs this will update the
PO with statistical information. With the latest information in
BBP_PDIGP table (statistical information) the query should work fine.

Clean_reqreq_up and BBP_get_status_2

I am bit confused about the use of these two programs Clean_reqreq_up and BBP_get_status_2.
What I understand from the different forums i read is that clean_reqreq_up creates the PO in the backend (classic scenario) after the shopping cart is approved and BBP_get_status_2 updates the shopping cart with the PO number so that the SC can be processed further( for goods confirmation).
Am I right gurus? If no , please illustrate with an example as above
Thanks in advance

Explanation :
The CLEAN_REQREQ_UP and BBP_GET_STATUS2 jobs will be configured to run in each EBP client to synchronize status data between EBP and R/3.
CLEAN_REQREQ_UP (Cleaner Job)
You can use this function for document types Shopping cart, (Local) Purchase Order, Confirmation, and Invoice to trigger a synchronization with the associated documents in the back-end system.

How to fill the application cache by scheduling a Bex report

Hi Experts,
I have a Query which take about 4 minutes to execute for the first time and when the same query is executed for the 2nd time it takes about just few seconds.
I tried using the broadcasting setting in portal to fill the OLAP cache for this query and executed it manually before executing the query in the morning, The Fill OLAP cache has run successfully but apparently the query executing for the first time takes the same time as it was taking earlier. There is not difference even after introducing the fill OLAP cache setting for this query.
On further analysis I see from the from the "Statistic Data for Query Runtime" that DBTRANS & DBSEL entries are available when the report was executed for the first time, this means the cache is getting filled only when the report is executed for the first time but not through the fill OLAP cache from Portal.
Can any one please let me know is there any other option available to execute the query before any user executes it, so that the entire report is available in the cache and the user doesn't have any complaints of performance. The report is executed only in Analyzer we do not have any web report.
Please provide your valuable input to over come this performance issue.
Thanks

Hi sam
You can broadcaste the report... and fill the cache...
Before setting up the broadcasting settings -- you need to enable the cache property for that particular query or info provider.
you can enable cache using the RSRCACHE or RSRT transaction ...
Check the below LInk
[Performance Optimization of Long Running Queries Using OLAP Cache|http://www.sdn.sap.com/irj/scn/index?rid=/library/uuid/f048c590-31a4-2c10-8599-bd01fabb93d4]

Hello, i have an issue
is it possible to chech how many incomming calls go to the trigger?
i mean, in script
if more than 5 calls during 10 seconds ,so send sms or email
is it possible?
thank you

Not natively for a JTAPI trigger; however, you could use the Get Reporting Statistic step to query the calls currently relavent to a CSQ. A script and the steps within it cannot normally see "outside" of that instance of the application with the exception of the Get Reporting Statistics step.
It is possible to use sessions to overcome this though. You could create a second session and add a known session mapping ID to it. The variables held in that session could contain variables, likely arrays in this case, that could hold this information. Each time the script is called, it can query this session for the data and act upon it. The script could also update the variables for the next script that executes. The same could happen when you send an Email (note: requires premium licensing or IP IVR): you could clear/reset the values.
You will need to handle what happens if the session has expired and been purged from memory due to inactivity. This shouldn't be a problem in your scenario because it would suggest inactivity, not high activity. You could reinitalize the session at that point.

Hi Prabha,
Aggregate Definition :
An aggregate is a materialized, aggregated view of the data in an InfoCube. In an aggregate, the dataset of an InfoCube is saved redundantly and persistently in a consolidated form on the database.
Use
Aggregates allow quick access to InfoCube data during reporting. Similar to database indexes, they serve to improve performance.
An aggregate is made up of the characteristics and navigation attributes that belong to an InfoCube. Characteristics that are not used in the aggregate are compressed.
Each component of an aggregate has to be assigned to a selection type. A selection type indicates the degree of detail to which the data in the underlying InfoCube is aggregated. You can choose one of the following selection types:
All characteristic values ("*"): The data is grouped by all values of the
characteristic or navigation attributes .
Hierarchy level (H): The data is grouped by the hierarchy level node. You can
also store values on the hierarchy levels of an external hierarchy .
Fixed value (F): The data is filtered by a single value .
For each InfoCube, you can set whether the aggregates of the InfoCube are compressed automatically when it is filled with data or after the roll up of data packages (requests).
1. You are in the Data Warehousing Workbench in the Modeling functional
area. In the InfoProvider tree, navigate to the required InfoCube.
2. In the context menu of the InfoCube, choose Manage.
3. In the lower part of the screen, select the Roll Up tab page.
4. Under the Aggregates group header, set the corresponding indicator in
the Compress After Roll Up field.
Standard Aggregation : This means how the key figure is going to be summarized normally for a specific set of characteristics .
Eg : Quantity across all the purchase items for a purchase Order
Exceptional Aggregation : You define how the aggregation should happen basing on a particular characteristic ( Usually time characteristic ) .
Eg : head count ( No of Employees ) in a organisation ..--> this should not be summarized on a daily basis..instead this should give a final value at the end of the month .
Aggregation is basically for keyfigures .
take a look at this doc, you will find all your answer:

Question1: how we will see the based on aggreagate what querys are running
I think "aggreegate maintance screen ---proposal -
query proposal" i am right ,if it is worng pls correct me?
Answer 1:
There are two tools that are used to analyze which aggregate is suitable for which navigation step.
You optimize the start screen of a query with the query Monitor (transaction RSRT) if you execute the function Execute + Debug.
With the trace tool (transaction RSRTRACE) you can draw several navigation steps, and process them again using the function DB Debugging (exact path: Transaction RSRTRACE > Goto > User Logs or All Logs > double-click on the log you want > DB Debugging).
Refer The OSS note 99010
Question 2: When i am creating a aggregate what charteristics we choose i mean based on report/some thing else?
Answer 2:
By refering the Statistical data and comparing the Proposed Aggregates we can create the aggregates.
The above RSRT and RSTRACE will be more useful tools to plan an Aggregate.

Creating query on Bex - Quaterly comparison for statistical & Actual

Hi All,
I would like to create a query for 'Quarterly comparison for statistical & Actual periods'.
My Key Figures should be
1) Plan 1st Qtr (Fiscal year, Period: 1 to 3, Value type : 1(Plan), Version : 0(Plan/actual), Valuation View: actual Value).
2)1st Qtr (Fiscal year, Period: 1 to 3, "Value type : 4(Actual),11(Actual statistical)", Version : 0(Plan/actual), Valuation View: actual Value).
3)Var 1st Qt (Plan 1st qtr - 1st Qtr)
same thing for 4 Quaters. finally with
4)Plan Year (Fiscal year, Period: 1 to 12, Value type : 1(Plan), Version : 0(Plan/actual), Valuation View: actual Value).
I created a structure and created key figures with selections and formulas as required. But I did not see any data when I ran this query.
The report was generated with 'no applicable data'.
I need to create this query with plan 1st Qtr, Ist Qtr, Var 1st Qtr, Plan 2nd Qtr, 2nd Qtr, Var 2nd Qtr, Plan 3rd Qtr, 3rd Qtr, Var 3rd Qtr, Plan 4th Qtr, 4th Qtr, Var 4th Qtr, Plan year. key figures.
Please let me know how can I create this query with these Key Figiures.
Any help would be appreciated. Please respond with the reply.
Thanks,
Aparna.

Hi
The best way is then to run a report with your KF without any restriction, and the different chars in the drill down: Fiscal year, Period:, Value type, Version , Valuation View
Then you can check that you have some information with the combination of values of your chars:
Fiscal year, Period: 1 to 3, Value type : 1(Plan), Version : 0(Plan/actual), Valuation View: actual Value.
If you find a actual Value in the fiscal period you are looking at, for the period 1 to 3, for the Valuation type 1, for the version 0, then create arestricted KF by adding the restrictions one at a time....You moght discover why you do not get the results

Statistic of the executions of the Query

Hi people,
I have to find out how many time my query was executed.
I know there is a table: RSDDSTAT, but it shows me only one register and this query was already executed many times.
Obs.: This query is based on ODS.
Could you help me please and say why the RSDDSTAT doesn´t show me a quantity of registers we waited to find?
And if there is other better way to find that?
Thank you a lot,
Rosana.

1.Goto ST03N
2.Select user mode as "Expert"
3.From Functions list (upper left pane) select "BW System Load" and under month selection, select your time duration
4.From the analysis view (down left pane) from the "Reporting" expand "Query Runtimes" and double click "BEx Queries".
5.Output is shown in right pane.
6.Select aggregation level as query.
7.Double click on the query name
8.A window popup with every run of the query.
9.To find out, how many times it has run, click on "Display Graphics" button. It will show with no of runs as X-axis
OR
if you are working with BW 3.5 you can look in table RSDDSTAT in BI 7.0 it is RSDDSTAT_OLAP.
Make a selction on the infocube and the OLAP Statistic Object which is the query ID/tech name and execute. Then you should see how often the query was executed, by whom and which date/time.

SQL Query statists?

I'd like to know if there is any easy, and convenient way, for someone to execute an SQL query an calculate, these measurments relative to the query:
1) The I/O performed
2)Number Read I/O
3) Number of Write out I/O
(such that 2+3 = 1
4) Number of buffered reads
5)Query Execution time
6) Query CPU usage
I've heard mention of such statisctis in views such as V$OSSTAT, etc.
But these views give the current values, and not the specific cumulative values. Such as: cummulative CPU usage time since start of the query; cumulative I/O since query begin, etc...
What is the right approach to this. Is it through the V$SESSION view? Would you about it by storing the V$SESSIOn values before the query, you run the query, and get the new V$SESSION values?

Well, actually i stayed here a little longer to try you part 2 of the manual.
It worked fine, following comes the output, originating from a spool file, of my first experiment:

SQL> quitIf you notice, at the end of the execution I print my statistics session environment. The statistics_level was set to ALL, as you advisied. But the output I obtained seems a lot more incomplete than the one I got from using the autotrace feature.
Am I missing something. Could it have something to do with the fact that I am running as system and not as sysdba? System shoul have enough permissions to access its session environment statistic values.
May be it's just a language issue (I'm not a native speaker either) but your understanding of Oracle's read consistency model seems to be questionable.No, you could be right; my understanding is questionable indeed. I am familiar with general concepts of concurrency.
Things like: Read uncommited data:
T1 Writes A; T2 Reads A -> Here is a conflict
This enough for you to not be able to guarantee that the execution is serializable.
T1 Reads A, T2 Writes A and commits, T1 Reads A - You get another confli, the Unrepeatable read.
And so on.
I am also familiar with the different levels of atomicity that databse systems in general give you.
Conflict Serializable, normally implemented by using the strict phase locking mechanism.
Repeatable Reads, you lock the rows you access during a transaction. You are guaranteed that those data values you access do not change value; but other entires in the table could be put.
Unrepeatable reads. Only the data you modify is guaranteed to stay the same. Only you write locks are kept throughout the transaction. And so on.
But anyway...
What you explained in your post is more or less what I was saying. In you case much more clear than in mine.
For instance, if a thread T1 reads A; a thread T2 Writes on A
In oracle, you could have the thread T1 read A again without geting an Unrepeatable Read error. This is strange: in a normal system you directly get an exception telling you that your vision of the system is inconsistent. But in oracel you can do so, because oracle tries to fetch from the Undo Table Space that same data objects consistent with the view of the system you had when you first accessed it. It looks for a block with an an SCN older than the current version SCN. Or something like that. The only problem is that those modified blocks do not stay indefinitely there. Once a transaction commits you have a time bomb in your hands. That is, if you are working with that is not at its most current version.
But you are quite right, I have not read enough about Oracle concurrency. But I have a good enough understanding for mu current needs.
I can not know everything, nor do i want to :D.
My memory is very limited.
My best regards, and deepest thanks for your time and attention.

BI statistic query

Hi All,
Could you please let me know the BI statistic query will give the data for, which user running queries against cube for last 3 months? we are using BI7
(Query name, user name, Day and time)
Regards,
Ravi

Hi Ravi,
Please check these queries..
0TCT_MC01_Q200
0TCT_MC01_Q201
0TCT_MCA1_Q202
0TCT_MCA1_Q200
0TCT_MC02_Q200
0TCT_MC02_Q202
I am not sure which one is for that in the above queries. you can check the queries in the business content and you can directly use the queries.one query will show you aggregated query runtime stats. and detailed query runtime stats i.e, by user by query by executions..you can see all..
Thanks,
Ashok
