Can we load Transaction data without loading Master data, explain  w.r.tSID

Can we load Transaction data without loading Master data, if so can you explain me how and when Surrogate Ids/ Dimension Ids  gets generated.

Hi,
We can load the transaction data without loading master data.
But for loading performance issues it is recommended not to load the transaction data first.
Every infoobject in the BW is identified by SID, that means which we are loading the transaction data, considering a scenario for an infocube, the system will identify the infoobject by existing sid against that infoobject in the bw and correspondingly create DIM id's.
Now consider the secnario where master data is not loaded and transaction data is being loaded.
Now the system should have sid to identify and infoobject and to create DIM id ( which is the combination of sid's of the characterisc in it)
And as the sid's are not yet created i mean as there is no referece for the master data, the system will first create the sid for that infoobject it means it will create a copy of the master data in that infoobject nd then create the dim ids based on it and then load the data.
Here the additional task of creating sids are also being done during loading the transaction data which hinders the loading performance
I hope this is clear5 now

  • What if i load transaction data without loading master data

    Hello experts,
    What are the consequences if i load transaction data without loading master data?Are there any other factors except the load performance because of SID generations etc and inconsistencies.
    <b>What kind of potential inconsistencies will occur?</b>
    Problem here is:
    when the transaction load starts a new master data such as employee(x) would be have been created in R/3 which does not exist in BW and hence transaction load fails.
    Thanks and Regards

    Hi Rao,
    In case you load the master data after loading the transcation data and if there is any look up at the master data in teh update rules, then you can delete and reconstruct the requests in the ODS/Cube so that the latest master data is pulled in in the data target.
    Make sure you do the Apply hier/attr change before doing the delete and reconstruct.

  • Transactional Data Load without Respective Master Data in Place

    Hi Folks,
    Could anyone let me know if i could load transactional data without loading the respective master data. If yes, well could you give me a scenario when you do it. Also could you let me know the option of how to load transactional data without master data in place.
    Best Regards,
    Prithvi

    Hi,
    You can load transaction data without loading master data.
    You have the option in the info package to load data even if no master data exists..
    You may use it in cases where your transfer rules/update rules or routines donot refer to master data tables to populate transaction data..

  • Can i upload  first  Transaction data rather than master data what will hap

    hai,
    can i upload  first  Transaction data rather than master data what happends going in bw regarding performance issues like indexes
    let me know
    regards,
    murali

    Hi Murali,
    you can load the transaction data before master data. The main impact will be, that the system has to generate sid's and has to populate the sid-table of the master data objects while loading the data to a data target (cube or ods that is activated for bex reporting). This basically means that your data loads will take some more time. Additionally, if you need the master data attributes somewhere in your update or transfer rules, you will not get the correct information.
    So basically it is always a good approach to load and activate the master data before loading the transactional data. But anyway, specially in the development environment I usually don't load all the necessary master data.
    regards
    Siggi
    PS: navigational attributes of the data targets will not be available until you loaded the master data and scheduled the attribute and hierarchy change run.

  • How can I re-install firefox without losing my data. It is Infested with ADS BY bame.

    Firefox is infested with "Ads by name".
    How can I get rid of it or how can I
    Re-Install firefox without losing any data?

    Couple other suggestions:
    Open the Windows '''Control Panel''', Add/Remove Programs. After the list loads, click the "Installed on" column heading to group the infections, I mean, additions, by date. This can help surface innocent sounding bundle items that snuck in with some software you agreed to install. Take out as much trash as possible here.
    Also, could you check whether Firefox has a non-standard '''connection setting'''? You can do that here:
    "3-bar" menu button (or Tools menu) > Options > Advanced > Network mini-tab > "Settings" button
    The default "Use system proxy settings" should piggyback on your Windows/IE "LAN" settings. But you can try "No proxy" to see whether that makes any difference.
    Finally, our support article [[Troubleshoot Firefox issues caused by malware]] lists '''cleaning tools''' other Firefox users have found useful. These on-demand scanners are free and take considerable time to run. If they finish quickly and especially if they require payment, you may have a serious infection. I suggest the specialized forums listed in the article in that case.
    Success?

  • How can you delete an app without losing saved data/progress?

    How can you delete an app without losing saved data/progress? Is there a way through iCloud? I have an 8gb 4th gen iPod touch. I have a lot of music, so with 8gb, space is limited. Some apps I have take up 20-30 MB. Some of these games I don't play that much, but I don't delete them because I have made a lot of progress (levels, scores, acheivements). It would be nice to delete some of these 30 MB apps that take up precious space, and them redownload them in the future when I have more space, but without having to start the whole game over.
    Also, I read somewhere that there might be a way to do this with iCloud, but I don't really know how.
    Thanks!

    This is the only way I know of.  It is messy though.

  • Can LSMW upload data other than Master Data

    Dear Friends,
    Can LSMW upload data other than Master Data, e.g. Want to upload the Vendor Invoice line items with single Debit and multiple Credit line items are there and also more than one GL a/c are involved.
    Thanks in advance.
    Regards,
    Mahendra Dev

    The answer is YES.
    There is no issue issue if you have different GL account.
    The issue is if you have multiple line item (which are differeing in each entry).
    For this, if you want to use LSMW, check for program, but not the recording method option.

  • Use of "with master data & with out master data" at DTP update level

    Hello experts,
    In DTP, I check "with out master data". When I try to send corresponding transactional data, It is showing SID related error. Can anybody suggest what is the use of "with master data & with out master data" at DTP level.
    Thanks in advance,
    Zakir.

    HI
    HI in DTP level If you set this indicator, the system terminates the update of the request if no values are available for a data record.
    Load the relevant master data before you load the transaction data.
    If you set this indicator, the system terminates activation if master data is missing and produces an error message.
    If you do not set this indicator, the system generates any missing SID values during activation.
    In DataStore maintenance, if you do not set the SIDs Generation upon Activation indicator, the No Update without Master Data indicator in the DTP has no effect.
    thx

  • Error while creating Data Source for master data attributes

    Hi BI Experts,
    Well its been some time for me that I have been part of Extraction in BI.I primarily handled reporting in my last assignments.
    I was trying extraction with flat files in SAP BI 7(new to sap bi 7 but very much familiar with BW3.5) but failed in the activity during master data attributes and text upload in infoobject (say IOSP_Mat).
    Here is the procedure that I did after creation of characteristic IOSP_Mat.I created a source system for flat file followed by data source for Master data attributes, i selected all the parameters correctly.i.e. csv file format, data seperator as   ,
    and other settings, now when i am trying to look at the proposed data in the next tab using Load example data.its not showing the desired result.The columns that I have maintained in Flat File is  MAT_NUMBER and MAT_NAME (with say 100 data in the file)
    same is the result when I am trying to load the text data too columns maintained are
    (LANGUAGE MAT_NUMBER Short Description)(same 100 data).
    now i used to rsa1old transaction  to upload the file using 3.5 version.i created info source for master data/text/hierarchies for  IOSP_Mat
    now when trying to upload it using info package for master and text data,I observe its(the data) not maintained in the characteristic IOSP_Mat.
    When I monitored ,I figured the data has not been even uploaded to the PSA level.
    Can you BI experts tell me the answer for this.
    Thanks,
    Srijith

    apologies to all of you for late response,
    was busy with some other activities.
    I don't remember the exact message,but I remember it was not loaded to even the PSA level.I will try it again and post the exact message.
    Thanks again for your quick response.
    Once again sorry to all of you for my late response

  • Is it possible to delete the keyfigures data in a master data object?......

    Hi Folks,
    can any one please tell me how can i delete a particular keyfigures data i na master data object.
    just i loaded wrong data to the keyfigure.i want to delete the whole data for the keyfigure only.so any one please help me .its very urgent.
    Thanks in advance.
    ashok.

    Hi Ashok,
       you  cant delete   particular attribute (as keyfigure  in ur case..) data for particular master data.. you need to delete entire master data once.. but before that you need to delete  transactional data related that master data.. and then load  once again with the correct data...
        but you can't delete particular attribute(key figure data)...
       otherwise.. you can load once again the correct data.. because.. if you load same data  means master data  will just ovverwrite the  previous data  so, you can try with this option also..

  • Read attribute value of a master data object's master data object

    Hi Guys,
    I have a peculiar condition where I need to read attribute value of a master data object's master data.
    Requisition (ZREQUI) is linked to Candidacy (ZCDCY) by object called Recquisition.
    Candidacy  (ZCDCY) is linked to Candidacy Activity (0CDCY_ACT) by object called Candidacy.
    I want to populate attribute called due date in ZREQUI by reading lowest value of due date value of 0CDCY_ACT. There can be multiple hits.
    If I can get the code to do this, I would really appreciate it.

    Here is the outline of the code ,as per my understanding..chk if it can help u
    In start routine write a select statement to pick all the data from 0cdcy_act.
    select 0CDcY_ACT ZCDCY  DuE_DATE from /BiC/P0CDCY_ACT
    into table itab1
    for all entries in source_package
    where ZCDCY = source_package-ZCDCY.
    as you need the lowest due date, sort the iTAB1
    sort itab1 by due_date  ZCDCY.   (default is acending order)
    In the field routine of your due date
    Read table itab1tnto wa_itab1 where
    ZCDCy = source_fields -ZcDcY.
    now duedate = wa_itab1-duedate.

  • Any difference between Master data and User master data ?

    Any difference between Master data and User master data ?

    hi
    A user master record defines the authorizations assigned to a user. Based on these authorizations one can access the master data.
    Master data - it is the data which is used long term in SAP r/3 system such as vendor master , material master, customer master,
    there is no such thing like user master data to the best of my knowledge
    hope this helps

  • Data load stuck from DSO to Master data Infoobject

    Hello Experts,
    We have this issue where data load is stuck between a DSO and master data infoobject
    Data uploads from DSO( std) to master data infoobject.
    This Infoobject has display and nav attributes in it which are mapped from DSO to Infoobject.
    Now we have added a new infoobject as attribute to the master data infoobject and made it as NAV attri.
    Now when we are doing full load via DTP the load is stuck and is not processing.
    Earlier it took only 5 mns of time to complete the full load.
    Please advise what could be the reason and cause behind this.
    Regards,
    santhosh.

    Hello guys,
    Thanks for the quick response.
    But its nothing proceeding further.
    The request is still running.
    earlier this same data is loaded in 5 mns.
    Please find the screen shot.
    master data for the infoobjects are loaded as well.
    I can see in SM50 the process at P table of the infoobject the process is.
    Please advise.
