Compress Requests Infocube

hi gurus...
i know that compressing requests move datal from E table to F table (or F to E) , so I have a basic infocube 7.0 with a lot of request with no compression, I m plannin to run compression of all request and include zero elimmination, i know that after compression a request can not be deleted no more, so i d like to know what r the dissavantages of doing this? amounts will be the same...
regards
joker

Hi,
Please remember the follwoing wrt compression :-
1. Start teh compression of few req together as it takes up a lot of system memory.
2. It adds one more step to the data loading process and hence the overall run of the process chain increases
3. Once compressed you ant delete the data request wise, you will have to run a selective deletion.
And the advantages are :-
Query access is faster
Cube size comes down - this helps in tasks like rebuild of aggregates etc.
Indexes are better maintained
Data Load is more efficient because the F Table has fewer requests ane lesser data.
Hope this helps.
Regards,
Rahul

  • Deletion of compressed request

    Hi
    I have two compressed in InfoCube
    Req A - 200 records Timestamp 2008
    Req B - 300 records Timestamp 2007
    Now I want to delete the request "B" from the Cube which is beneath req A in the Cube.
    I have already deleted the data for the Req B via selective delete, now the only thing I have been asked is to delete the request.
    Can I delete the same via RSICCONT table and if so what is the Impact of the same.

    Hi DPN,
    Once u do the compression then the request idds will be deleted and the data will move from F table to E table, If u want to delete the compressed data then u have to do Request reverse posting for this you should have the data in PSA. If u do this all the in that request will be multiply with -1 and send to cube with new request, after that u have to do the compression so that + and - values will be cancelled.
    I have already deleted the data for the Req B via selective delete, now the only thing I have been asked is to delete the request.
    I dint understand this. Remember request ids will be deleted once u do compression.

  • Compress an InfoCube

    Please explain the steps to compress an InfoCube with marker update"

    Keith

    Hi Keith,
    RSA1 --> Your Cube --> right mouse click --> Maintain --> Tab Compression --> Select request till you want to compress --> Flag Marker --> Start compression.
    It is a very slow process if you have a lot of request/data, try to execute when you have not jobs running.

  • How to delete the compressed Request ID in the info cube... ?

    Hi BW Gurus,
    one of the info package will upload the request in to three data targets and failed due to error with duplicate records.  I am able to delete the bad request in two data targets and facing problem with one data target due to the request is available in green and got compressed. 
    The reasons why i am unable to delete the request in that data target is it is already got compressed and rolledup.
    I tried with selective deletion based on same request ID  i have done that successfully but the request still presents in the data target.  I have checked in listcube and found no data for the request id.
    now i have one more question like the request has bring down to status not ok in the monitor and done selective deletion will it be a problem on the data missing please advise me if any data missing will occur for the particular data target.
    can any one help on this. Thanks in Advance.
    Venkat.

    Hi Venkat
    You have one way to delete the compressed request
    But this is possible only if u have the request in PSA
    If the request is in PSA, do reverse posting
    This will nullify the particular bad request by changing the press sign into - and - sign into + for all the records went in the cube for that particular request

  • Deletion of compressed request in BI 7.0

    Hi,
    I have loaded info cube by using process chain, in process chain I added compressed.
    How to delete the compressed request from info cube .
    Note : System is BI 7.0.
    Thank you for advance.
    Regards.
    Suman.

    Hi Suman,
    Greetings.
    Yes you can perform selective deletion of data from the compressed request in the Cube.
    Either you can go to Manage option in the Cube and schedue there or use TCode delete_facts and delete from there.
    If in case you want to schedule this deletion in a process chain, you will need to generate the program using delete_facts in dev and copy it to a Z program in Dev and add that in a process chain. Now migrate the program and the process chain.
    Schedule it howvere you want it to be.
    Let me know if it helps.
    Thanks

  • Deletion of compressed request in cube

    Hi All,
    Is there any way i can delete a compressed request in a cube
    and please keep mind that I also have other request in the cube there should not be deleted at any case as the source system of these requests is not connected to BW system now.
    Regards,
    Antony

    Hi,
    no, you can't delete a compressed request.
    What you can do is to post the request reversal (all keyfigs x -1) provided you still have the data in the PSA or you can reextract it
    or you can selectively delete the data of this request if you can find a selection criteria of the data to be deleted....
    can you give more details on this request? was it a delta? coming from which DSource?
    hope this helps...

  • Deletion of compressed requests

    Hi,
    can anybody tell me is there any way to delete compressed requess in cube.

    Hi,
    You can not delete a compressed request.
    When you compress a request it moves from the F fact table to E fact table. Here in the E fact table you do not have the request-id column, hence the data can not be recognized with the request number when it is compressed(when the data is in E fact table).
    One thing you can do is delete the data based upon selections >> Selective deletion can be performend in such cases if you have any particular parameters ex: date, doc no. range etc etc. to do so.

  • Delete Compressed requests

    Dear All,
    I am trying to delete  the compressed request from the cube ;but it seems that deletion has not occured.
    Please sugeest for the same.
    Regards
    Nidhi Walia

    Hi Nidhi,
    You cannot delete by the request ID if it is compressed. The other option would be to attempt Selective deletion by cube contents, if you can accurately highlight or pinpoint the data loaded by way of this request. Selective deletion is irreversible.
    Once the requests are compressed the request number is set to 0.

  • Compressed request not visible

    Hi experts,
    I have a infocube with two request (1000 records and 90 records). The request with 1000 records is compressed. When I go to view contents of the InfoCube, I see records for only request with 20 records.
    How can I see contents of both request.

    Hi,
    how do you view the content (the fact table or the infocube content)?
    via the fact table it may only show the F fact table data (non compressed), compressed will be in the E fact.....
    via the infocube content (or transaction LISTCUBE), it should show all your data if you don't specify any selection criteria...
    Check that your request has the status "ready for reporting" in the request tab of the cube...
    check if the compression job ended successfully...
    let us know...

  • How to delete the rollup and compress request from the cube

    Hi Experts,
    I have a requirement, one request was updated into the cube and it was been rollup and then compressed.  As the request was compressed so based on request id we cant perform the deletion.
    So it is possible with selective deletion.  Now before performing the selective deletion do i need to deactivate the aggregates. 
    Help me out on this.
    Regards
    Prasad

    Hi.........
    U hav to deactivate the aggregates................bcoz.........Selective deletion is only possible with uncompressed requests...............ie from F fact table...........after compression data moves from F fact table to E fact table.............. you can't do selective deletion on E fact table.........So first deactivate the aggregates............then do the selective deletion..............then again activate the aggregates..............and do the aggregate filling job manually in RSA1..............but I will suggest u delete the request...............bcoz any how u hav to deactivate the aggregates............and in case of selective deletion u hav to be very particular................if ur load is not taking much time............then delete the request and repeat the load............

  • How to delete a compressed request?

    I have a full update request in my material movements cube that I want to delete and then attempt to reload from the PSA.  When I go into the cube, highlight the reqeust, and click DELETE I get the message "Request ID 0000055001 is aggregated, compressed or scheduled"
    How can I delete it?
