Data archiving for Write Optimized DSO

Hi Gurus,
I am trying to archive data in Write Optimized DSO.
Its allowing me to archive on request basis but it archives entire requests in the DSO(Means all data).
But i want to select to archive from this request to this request.(Selection of request by my own).
Please guide me.
I got the below details from SDN.Kindly check.
Archiving for Write optimized DSOs follow request based archiving as opposed to time slice archiving in standard DSO. This means that partial request activation is not possible; only complete requests have to be archived.
Characteristic for Time Slice can be a time characteristic present in the WDSO, or the request creation data/request loading date. You are not allowed to add additional infoobjects for semantic groups, default is 0REQUEST & 0DATAPAKID.
The actual process of archiving remains the same i.e
Create a Data Archiving Process
Create and schedule archiving requests
Restore archiving requests (optional)

  • Testing Delta Consistency for write-optimized DSO

    Hi,
    Please do let me know how to carry  testing for delta consistency for write-optimized DSO.
    Is it just to check whether the check box under the settings.. "Check Delta Consistency " is checked or the other way.
    Please do let me know.
    Thanks & Regards,
    Lavanya.

    Hi,
    The delta consistency flag for W-O DSO is used to ensure data consistency between the w-o DSO and any target propagated to. zfor example, you have dataflow ZWDSO1 -> zsdso1. ZWDSO1 has the flag 'check delta consistency' set to ON. You load data from ZWDSO1 to ZSDSO1 via request 1.
    When the load is successful, if you try to delete the request 1 from ZWDSO1, deletion should not be possible; also you will not be able to change the flag to OFF as delta has already been propagated, and if you change the flag, delta consistency might be lost!
    Now, if you delete request 1 from ZSDSO1 and then try to delete request 1 from ZWDSO1, deletion should be possible.
    Hope the explanation helps!

  • Error while deleting data from a write optimized DSO using a Process Chain?

    Dear Bwers,
    I am facing a strange error while using process chains to delete data from data target which is a write optimized DSO. The process shows as failed but the data gets deleted in the DSO. The error message is as below. Did anybody have a similar problem? Any suggestions.

  • Semantic keys for write optimized DSO

    Hi experts,
    Can anyone tell me more about semantic key in a write optimized DSO ?
    I have a DSO cocnerning sales orders with 3 Datasources.
    How can you define the semantic key ?
    I have schedule line number - document number and position number in semantic key but when I load the PSA, I have an error with duplicate data.
    Any clues ?
    Thanks.

    Hi Oliver,
    If you specify any of the charaterstics symantic fileds, when you load data to the DSO, if any error record comes the following records which has the same characterstic(symantic) combinations will n't update into DSO even though they are correct. they will be written to error stact to ensure the data quality.
    In write optimized DSO, technical fileds are automatically taken, then in the semantic fileds you can specify the charcterstic which should act as primary keys(but not exactly).
    Thanks

  • Disk throughput drops when inserting data packages in write-optimized DSO

    Hi all,
    we are currently testing our new freshly installed SAN.
    To see the performance gain in BI, I'm currently doing some test loads.
    And during the monitoring of those loads, I noticed something I'd like someone to explain :-):
    I execute a DTP from PSA to a write-optimized DSO.
    The n° of parallel processes = 9
    Update method = serial extraction, immediate parallel processing
    N° of records transferred: +23.000.000
    Ok, in the first phase (read the PSA) only one process is used (serial extraction).  When I look in OS07, I notice we have very good throughput: +66.000 TransfKB/s. Very nice!
    But as soon as BI starts inserting the data packages, and parallel processing kicks in, the throughput drops to 4K or something, and sometimes we get 20K at max.  That's not too good.
    We have a massive SAN , but the BI system does not seem to use it?
    I was wondering why this is the case.  I already toyed around with the package size, but it's always the same.
    Also I noticed that the allocated processes don't seem to be active.  I allocated 9 BTC processes to this load.
    They are all used, but we only see 3 inserts at the same time, max.  Also in the DTP-monitor, only 3 packages are processed at the same time.  As it's a write-optimized DSO, RSODSO_SETTINGS does not apply I presume.
    Any ideas?
    tnx!

    Hi,
    can you pls try to give some filetr in DTP and try to pull the data.
    I am not sure why first data package is taking long time and otehr data package is taking less time..
    Do you have any start routine..If datapak = 1.. the do this logic..
    Pls check..
    regards

  • Duplicate Error while loading data to Write Optimized DSO

    Hi,
    When i do a dataload for Write Optimized DSO, I am getting an Error as "Duplicate Data Record Detected".  I have Sales Document Number, Fiscal Year Variant & Billing Item as Semantic Key in the DSO. 
    For this DSO, I am getting data from a Test ECC system, in which most of the Sales Document Number column is Blank for this Datasource.
    When i go into the Error Stack of the DSO, all the rows whichever has Sales Document number as Blank are displayed.  For all this rows, the Item Number is 10.
    Am i getting this Duplicate error as the Sales Document Number is Blank & Item number is 10 for all of them?  I read in Threads that Write Optimized DSO doesnt care about the Key Values, it loads the data even if the Key values are same.
    Any help is highly appreciated.
    Regards,
    Murali

    Hi Murali,
    Is the Item Number a key field ?
    When all the key fields are same then data gets aggreagted depending on the setting done in the transformation for the key figures. These 2 options for key figures are :
    1. Add up the key figures
    2. Replace the key figure
    Since the Sales Document No is blank and Item Number is same then their is a possibility that the key figures for these records might get added up or replaced and thus due to this property of SDSO it might not be throwing error.
    Check the KF value in the SDSO for that Sales Doc No and Item No. and try to find out what is the value for KF. It may have addition of all the common data fields or the KF value of last common record.
    Regards

  • Write-Optimized DSO data deletion

    Hello All,
    We have a requirement to delete old data from a write-optimized DSO. The specific requirement is to delete the data older than 15 days (requests older than 15 days) in the DSO. I could not find any process type that could be used in process chains which would automatically delete the old data based on our settings (similar to the one used for PSA or Change-log deletion). Has any of you come across a process type or a batch job that be scheduled to delete old data in a Write-optimized DSO. Your help is much appreciated.
    Thanks,
    Veera

    Hi Nagesh,
    Thanks for your answer. But the use of these function modules would still require custom development to identify the requests to be deleted. We are trying to see if SAP has any standard process for deleting the old request out of a write optimized DSO or if anyone was successful in achieveing this with least amount of customization.
    Thanks,
    Veera

  • Unable to delete request from write-optimized DSO (Error during rollback)

    Hi Gurus,
    I am trying to delete a delta request from a Write-Optimized DSO. This request was uploaded with a DTP from another Write-optimized DSO.
    The actual overall status of the request is RED and the description of that status is now: 'Error during rollback of request DTPR_4JW6NLSVDUNYY3GTD6F4DQJWR; only rollback allowed'.
    I checked the log of all Request Operations in DataStore (from the same line where the red request is now) and I see my several attemps to delete this request under a RED radiobutton with the title Rollback.  The details for this error are the following:
    Could not delete request data from active table
    Message no. RSODSO_ROLLBACK114
    Diagnosis
    The system could not delete the request data from the active table of a write-optimized DataStore object.

  • Changes to write optimized DSO containing huge amount of data

    Hi Experts,
    We have appended two new fields in DSO containg huge amount of data. (new IO are amount and currency)
    We are able to make the changes in Development (with DSO containing data).  But when we tried to
    tranport the changes to our QA system, the transport hangs.  The transport triggers a job which
    filled-up the logs so we need to kill the job which aborts the transport.
    Does anyone of you had the same experience.  Do we need to empty the DSO so we can transport
    successfully?  We really don't want to empty the DSO's as it will take time to load? 
    Any help?
    Thank you very muhc for your help.
    Best regards,
    Rose

    emptying the dso should not be necessary, not for a normal dso and not for a write optimized DSO.
    What are the things in the logs; sort of conversions for all the records?

  • Multiple data loads in PSA with write optimized DSO objects

    Dear all,
    Could someone tell me how to deal with this situation?
    We are using write optimized DSO objects in our staging area. These DSO are filled with full loads from a BOB SAP environment.
    The content of these DSO u2013objects are deleted before loading, but we would like to keep the data in the PSA for error tracking and solving. This also provides the opportunity to see what are the differences between two data loads.
    For the normal operation the most recent package in the PSA should be loaded into these DSO-objects (as normal data staging in BW 3.5 and before) .
    As far as we can see, it is not possible to load only the most recent data into the staging layer. This will cause duplicate record errors when there are more data loads in the PSA.
    We all ready tried the functionality in the DTP with u201Call new records, but that only loads the oldest data package and is not processing the new PSA loads.
    Does any of you have a solution for this?
    Thanks in advance.
    Harald

    Hi Ajax,
    I did think about this, but it is more a work around. Call me naive but it should be working as it did in BW3.5!
    The proposed solution will ask a lot of maintenance afterwards. Beside that you also get a problem with changing PSA id's after the have been changed. If you use the posibility to delete the content of a PSA table via the process chain, it will fail when the datasourcese is changed due to a newly generated PSA table ID.

    Harald

  • Problem loading data into write optimized dso.....

    Hi ,
    I am having problem loading the data from PSA to write optimised DSO
    I have changed the normal DSO into a Write Optimised DSO. I have 2 data sources to be loaded into the write optimized DSO. One for Demand and one for Inventory.
    The loading of Demand data from PSA to DSO happens fine with out any error.
    Now while loading the Inventory data from PSA to DSO , i get the below errors
    "Data Structures were changed. Start Transaction before hand"
    Execption CX_RS_FAILED Logged
    I have tried reactivating the DSO, Transformation, DTP and tried to load the data again to the write optimised DSO, but no luck, I get the above error message always.
    Can some one please suggest me what could be done to avoid the above error messages and load the data successfully.
    Thanks in advance.

    Hi,
    Check the transformations is there any routines written.
    Check your Data struture of cube and DS as well.
    Is there any changes in structure.
    Data will load upto PSA normally, if is there any changes in struture of DSO, then the error may occur.just check it.

  • Sematic group for a write optimized DSO

    Hello,
    I am loading from a datasource to a write optmized DSO. While doing so, I am not able to set semtantic key/group for the DTP.  I have turned error handling on using the setting 'Valid records update, No reporting(request RED)'.
    Is this setting not possible for a write optimized DSO? if not why not? and if yes, what am i missing!?
    Thanks a lot in advance,
    Prakash

    Thank you,
    here are my findings:
    - if data has been loaded with delta using the DTP, it is not possible to change the sematic groups any more - all requests have to be deleted first
    - the error handling must be turned on
    The issue is resolved.

    Hi,
    Iam facing the similar problem.
    Iam using Write Optimized DSO and i have got only 1 req in PSA (have deleted all previous req from PSA and DSO).
    When iam doing a delta load from PSA to DSO, i expect to see only that 1 req to get loaded into DSO.
    But, its picking up the data from 3 other reqests and doubling the records...
    Can you please help me, how did you managed to get out of that isue?

  • Unable to delete data target contents of Write-Optimized DSO in Process Chain

    Hi Experts,
    We are using SAP Net Weaver BW 7.01 version and we need to delete the entire data target contents of Write-Optimized DSO in the process chain before the next data load.
    I included this step in process chain but still it is failing with errore message"Message not found (in main memory), Drop Cube Failed In Data Target"
    This process type is working during BW 7.0 version but not in BW 7.01 version.
    However i found that we can use the program RSSM_DELETE_WO_DSO_REQUESTS to delete old requests in the Write-Optimized DSO for BW 7.01 SP07 as per SAP Note 1437407 but still it's not working even after implementing this program as the Prerequisite to delete the request is the data mart status should be updated where it is not happening for the program.
    We had an process type option to 'delete the requests from Write-Optimized DSO' directly in BW 7.3 but still not available in 7.01 version.
    Could you please suggest me on how to resolve this issue in BW 7.01?
    Many thanks for your help in advance.
    Regards,
    Madhu

    Create ABAP program as attached code.
    Then you can use that ABAP program in process chains through ABAP variant
    ABAP varaint should have following properties
    Select call mode as Synchronous; call from Local; and Program
    Give your ABAP program name in "program name" and create one program variant for each write optimized DSO.
    Please refer how to use ABAP program in process chains for further details.
    Hope this helps
