When do we compress the request in cube. ?

Hello all,
We have been live for a few months now. After how many days/weeks/months should we compress the request in cube. ?How often do we have to compress the data in the cube.
I know once compress than we cannot delete the data by request but we there is an issue and we need to delete data completely from the cube that is possible right ?
Thanks in advance

How often Compression needs to be done depends on the volume of data that is loaded everyday. Unless the volume of records loaded everyday is unusually high, doing compression once a week might be good enough.
Also you are right abt losing the ability to delete by request in the infocube after compressing the request. But we dont necessarily have to delete the whole cube incase of issues. There is always the option of doing 'SELECTIVE DELETION'.
Next, when doing the compression you have an option of mentioning the date range. Choose the option of compressing requests that are older than 4 days (arbitrary) to have a buffer for deleting the request incase of issues.
Hope this helps!

Unable to Compress the request of a Cube

Hi All,
I was trying to compress the cube data,At one request I got stuck. When ever I try to compress that request manually, but it is unable to compress the request and sends the following job logs
Job started
Step 001 started (program RSCOMP1, variant &0000000000190, user ID XXXXXX0006)
Performing check and potential update for status control table
No requests needing to be aggregated have been found in InfoCube 0XX_X01
Compression not necessary; no requests found for compressing
Compression not necessary; no requests found for compressing
Job finished
After further analysis, I observed the request which I am compressing , has an selective deletion.Since its is 2year old data I would like to compress the data,please suggest is it possible to compress,If the request has selective deletion.
please suggest.
Thanks & Regards,
Abdul

Hi Abdul,
Check that, if the cube that is being compressed feeds the data to a different InfoProvider, if yes then complete that laod first and then do the compression. this might be the reason sometimes. if the cube is not feeding anything currently try compressing the request again.
In some cases ,when the compression is manually performed (in the tab collapse of the cube) no compression would be done. In those cases you can try creating a process chain with only the compression step. This often solves the problem.
If both the above process don't solve your problem,
Try the SAP note :407230 (such problems occure after installing SP15.)

Exception CX_RS_ERROR occurred when trying to run the DTP from Cube

Hi everyone,
I've run the DTP & loaded the cube using normal transformation routines , it works fine in the Dev Sys but not in quality & production. I've access only to the Dev sys. In Qual & Prod when trying to run the DTP from Cube to open HUB
we're getting the following error
Exception CX_RS_ERROR occurred (program: CL_RSTRAN_TRFN================CP, include: CL_RSTRAN_TRFN================CM024*
My system support package level is SAPKW70106.
I've found note 920338 but is for SAPKW70107.

Hi,
The issue seems to be with the one of the routines in the transformation and similar kind of the issues were solved by retransporting the DTP & the related transformation.
Kindly reactivate the DTP and transformation in the source and execute a new request to transport the DTP, transformation and related routines to Quality & Production again.
Hope this helps.

Differences in compressing the requests.

Hi experts,
What is the difference between compressing the request with:
No marker update ( Checked ).
No marker update ( Not checked )
Zero elimination.
And also if we fill the setup tables through mcnb ( Initialization of stock ). What exactly it mean ? ( Is it the stock which is there at the time we fill the setup tables ? ).
And also suppose if we filled the setup tables of 2lis_03_bx through mcnb today and through oli1bw we need to the fill the historical data of 2lis_03_bf .
Here what should be the date range.Is it upto yesterday? ( Bcz we have filled setup tables of bx though mcnb today ).
Please explain me in simple words.Full points will be assigned.
Regards,
Bhadri M.

Hi
Stocks are calculated using the stock marker and appliying the movements types and quantities to that marker.
If you compress cube with no marker update checked, movements compressed doesn't update the stock marker and are viewed as historic data, then after initialization the mark must be uncheckd in order to update the stock marker.
To be more precise and simple marker update Updates the stock values and NO Marker does not.
Generally BX upload has to be compressed with marker update and BF(and UM) delta init has to be compressed with NO Marker because Stock was updated with BX. And delta loads of BF and UM has to be compressed with marker update because these brings new Material movements which will has to give effect to stock.
Sorry for edition but was unable to post
Zero Elimination Explaination
Compression is nothing but moving the data from F fact table to E fact table by losing its request numbers.
For cumulative key figures(compression)
Here we have a option called zero elimination (it is applicable only for cumulative key figures). If you want to avoid the Info Cube containing entries whose key figures are zero values (in reverse posting for example) you can run a zero-elimination at the same time as the compression. In this case, the entries where all key figures are equal to 0 are deleted from the fact table.
This is permitted only for Info Cubes , where key figures with the aggregation behavior SUM appear exclusively. In particular, you are not permitted to run zero-elimination with non-cumulative values.
Thanks

Compress the Request with Zero Elimination

I delta load the transaction data into Infocube by InfoPackage and compress the Request ID manually without select 'with Zero Elimination'. Now I wanna Compress the request ID with Zero Elimination again. Could you give me some hits on that. Many Thanks .

hi,
There're two programs that work for me.
1. RSCDS_MERGE_DUPL_REF_POINTS - this is to actually compress the records.
2. RSCDS_NULLELIM : - To remove the records with 0 value i.e. null Elimination
Although, SAP doesn't recommend using them if your compression is working fine.
You may want to try them in your non-production system first.

Compress the request of inventory cube 0ic_c03

Hi experts,
I want to compress the infocube 0ic_c03 daily for the delta requests through process chains.
In the process chain, process types there are 2 options:
1.Collapse only those requests that were loaded XXX days ago
2.Number of requests that you do not want to collapse
Which one i should select and how many days i need to go.
I want to the daily delta request to be compressed.
Pls guide me accordingly.
Regards,
Nishuv.

Hi,
Inventory data is non-cumulative data and we usually keep 30 days. Once compressed we cannot make any changes if there are any errors on particular day. We had problem when FICO consultants changed valuation in the systems directly and we were not aware of that. Later when values in the FICO is different in Inventory then we figured out that there were some manual changes in FICO. Luckly we didn't compress those requests. Later thru some routines we fixed the issue.
Thanks

Why do You compress the data in cube

Why We Compress Data In Fact table of Cube(0IC_C03) After loading Stock Intialization Data into Cube.

Hi,
Generally the request compression is done to reduce the no. of partitions of Fact table, so that the query performance increases. It helps in reducing the no. of records in infocube by aggregating duplicate records. Which internally reduces the data base size.

Compress the requests without opening PRD client

Hello experts,
Everytime we take INIT loads into 0IC_C03, we have to compress the BX,BF & UM requests. But it is only possible after opening the PRD client.
Can anyone guide how to compress these requests without opening client? Is there any special auth. required for this?
Please reply.
All answers will be rewarded.
Regards,
Roy.

Roy,
When you open the client and compress - are you asked for any request.
What I think is happening is that there might be some tables which have entries being deleted and recreated. For deleting the entry you will have to open the client if the table is not maintainable.
As a process if no request is triggered then it is a table issue - check if you can set any namespace to modifiable and resolve this or if you are getting a request then you will have to open the client.

Problem with finishing install of Flash Player on a Mac. When finishing by entering the requested password, the dialog box jiggles as if the p/w is invalid. But it works in the Adobe site.

I am trying to install Flash player on my Mac. All the steps are working as they should, until the point where I am asked to enter my password. I do this, and the dialog box jiggles as through the p/w were invalid. However, it works to sign in to the Adobe site. I just changed it to be sure and checked again.

There is no password required to download or install the Flash Player. Chances are your Mac is requiring you to enter its password to allow the installation to occur.

Unable to compress a request.

I am unable compress a request by manually and by scheduling in the process chain also it is not compressing.
when i open the collapse tab it saying No valid request exists for compressing
then i entered manually with request id. job finishing without compression and i found in the job log(SM37)
*No requests needing to be aggregated have been found in InfoCube
*Compression not necessary; no requests found for compressing
*Job finished
in 10 seconds.
Process chain is also completed successfully without compression.

Thanks in advance.

Hi,
Note: Is "Tick" mark there against your request in requests tab?
If you are able to see your request in requests tab as not compressed, then delete this request and reconstruct it back from the Reconstruction tab. But please check in reconstruction tab to make sure the same request is available.
After the above activity, you can try to compress this request.
Hope you understand.......
