First Loading of Master data into ODS

Hello BW gurus,
I have read the below mentioned sentence in a material stating that
'By using flexible updating, it is possible to write master data from different sources into a consolidated object (master data ODS object) before this is stored in individual master data tables.'
1)  why master data from different sources is being written into ODS first , before it is stored in individual Master Data tables ?
2) Is every master data from source systems first loaded into ODS  before it is stored in individual Master Data tables?

hi,
1) why master data from different sources is being written into ODS first , before it is stored in individual Master Data tables ?
Ans - In real time scenarios y may have to load data from various source system (liks sap,non sap,flat file).also more than on r3 source system is also possible. hence to have consolidation of the master data based on source system we load master data to ods first. but is not always. one few master datas like - Batch number,delivery number,invoice number. u can also load directly to master data tables using direct update.
2) Is every master data from source systems first loaded into ODS before it is stored in individual Master Data tables?
not mandatory, it depends on requirement.

  • Loading Master Data into ODS

    Hi,
         Can anyone tell me how to load the master data into the ODS?
    Thanks

    Dear Yadav,,
    U can load the master data to ur ODS..
    The Process is same as loading Transaction Data into ODS but..
    1. U need to do  flexible Update instead of Direct Update...
    2. Maintain all the Attributes in ur DATA part...
    3. The record on which Updation depends should reside in the KEY FIELD section.
    But there is difference in loading master data to info object and ODS..
    If loaded in Info Objects..REusability is there.
    But in ODS no reusability...
    Hope this helps u...
    Assign points if helpful...
    Best Regards,

  • Loading InfoObject master data into Cube

    Hi Guys,
    I have a  question. I created an InfoObject as a data target and loaded data into that data target. I created a cube and I want to include this infoobject in the cube. Now How do I load data into this cube from the InfoObject.Because the InfoObject doesnt have any option to select data targets, since it is master data.
    Data is being loaded into the InfoObejct. But when I check the cube there is no data.
    How do I load this master data into the cube without update rules?
    Thanks in advance.

    Hi,
    i think u need load some value to transaction data so that you can report on it, but how you are going to decide which row will be having which value from master data? in general value for this should come from transactional data, or you could assign some constant value to it.
    Do you want to use any attribute of Inoobject in report? And if you have any key value for that coming from Transaction data, you can use rule type as read from master data
    It depends upon your requirememt.
    Since you want to restrict the values of the cube which are going into the report then you should include this object into the cube.
    In any case if you want to restrict the value of the transactional data in the cube with either the value of the objects ot the attributes of object you will have to add this object into the cube.
    As you said you can load master data and use in report but how you are going to use it..............you will have to include it in the cube to use it.
    Also you can check whether this object is attribute of some other object already in the cube in that case you can make it navigation attribute and then use it for the restrictions in the cube.
    In this case only you do need to add it to the cube,But if it not an attribute of any object then you must add it to the cube.
    You have to get the value of your infoobject into Cube from datasource, even though you want to use attributes only.
    You will have to add it and it wont have any effect the transaction data getting loaded into the cube will be different from the master data only SID's are matched during loading of the data.
    You should load separate master data into the 0recontract infoobject with the master data source and make the respective object contract type and contract category as navigation there.
    Also you should add 0recontract to the cube and update it from the transaction data source as you have said that it can be updated.
    Then just do the normal restrication at the report level
    You can make this display attribute as naviagatioonal first in the master data object and then in the cube make this attribute as navigational.
    then you can use it to restrict in the cube
    You can use Category as InfoObject in your cube, and while loading data for your infoobject in the rule type you can use option as reading from master data. It will take key of infoobject, and will update attribute value in your cube.

    You can also restrict with attributes value, Just in the restrcition of your infoobject in query designer, slelect left-botton button of 'Dipaly Other Values', here you can select you attribute and its value for restriction as well

  • Error while loading the master data into hierarchy

    Hi,
    When i am trying to load the master data into a hierarchy, it is showing me the following error.
    "Invalid Entry, hierarchy xxxxxx does not exist".
    Can you please tell me what might be the possible cause for this error.
    Thanks,
    Prateek

    Hello
    Have you created a hierarchy, I mean go to Transfer structure->Hierarchy structure 
    ->create hierarchy, put a check of whether it is sorted or time dependent etc. after that while loading data through infopackage just check that you have selected an appropriate hierarchy name in hierarchy selection tab.
    Hope it will help!!

  • Master data into ODS

    HI,
    How do we load from master data infosource into an ODS , using datamart concept. can any one give me step by step details..
    When i try to assign infosource to the ODS in the update rules...it says " INFO OBJECT 0recordmode missing from the infosource"
    Thanks in advance
    Message was edited by:

    Hi Harshi,
    Add 0recordmode in master data infosource and ROCANCEL in tranfer structure
    also check this info,
    Message RSAU128 'InfoObject 0recordmode missing is an information message, you can activate the update rules even without 0RECORDMODE. The field is required for the delta method of InfoSources with connected DataSources from an SAP R/3 system. For FlatFile DataSources or external DataSources InfoObject 0RECORDMODE does not need to be contained in the transfer structure of the InfoSource, or it does not need to be filled separately in the transfer rules. In the transfer rules when maintaining the transfer structure, the delta method for flat files or external DataSources is determined by field Update mode. In InfoSources that get their data exclusively from flat files or external does not need to be contained in the you can ignore the above-mentioned message when creation update rules."

  • Error in Loading Project master Data into BW from R3

    Hi Experts,
    Actually I am trying to load Project Master Data from R3 to BW through a BW Process chain, Its a daily activity which we are performing since long time.
    But since last 2 days loading is getting failed with an error in ST22 in source system (R3):
    Runtime Errors         OBJECTS_OBJREF_NOT_ASSIGNED
    Exception              CX_SY_REF_IS_INITIAL
    Date and Time          27.09.2011 01:47:15
    Short text
         Access via 'NULL' object reference not possible.
    What happened?
         Error in the ABAP Application Program
         The current ABAP program "CL_CGPL_TASK==================CP" had to be
          terminated because it has
         come across a statement that unfortunately cannot be executed.
    Error analysis
        An exception occurred that is explained in detail below.
        The exception, which is assigned to class 'CX_SY_REF_IS_INITIAL', was not
         caught in
        procedure "PREPARE_FOR_RELOAD" "(METHOD)", nor was it propagated by a RAISING
         clause.
        Since the caller of the procedure could not have anticipated that the
        exception would occur, the current program is terminated.
        The reason for the exception is:
        You attempted to use a 'NULL' object reference (points to 'nothing')
        access a component (variable: "ME->OUTLINE_PARENT").
        An object reference must point to an object (an instance of a class)
        before it can be used to access components.
        Either the reference was never set or it was set to 'NULL' using the
        CLEAR statement.
    I tried to reload the data but no help, I am not sure how to reolve this issue, I also contacted to BASIS even they are not aware of this error.
    I am seeking help from you guys.
    Please help to overcome this problem...!

  • Any easy way to load different master data into BI?

    Hi,
    I have started setting up our BI system. I have to load master data for different things - company code, customer, vendor, material etc.
    For all of the standard BI Content has InfoObjects, Infosources and Datasources. However, I need to create InfoPackage, Transformation and DTP and process chain for delta load and PSA deletion. This seems to a tedious process to do for all the master data objects.
    Is there any different way of doing it?
    It seems surprising one has to repeat all these for each BI system.
    Regards,

    Hi Gitesh,
    If you are working on BI 7 then you can always migrate your datasources and migrate data flow accordingly. The only thing you need to take care of LO datasources and transfer rule routines as something they didnt copy.
    Please refer the following link to migrate dataflow.

  • Loading Master data into BPS through layouts

    Hi SAP Gurus,
    Is it possible to load the master data into BI-BPS through layouts(in BI 7.0
    Thanks in advance.
    Regards
    Pradeep

    Hi Pradeep,
    if its combination of charactertics & keyfigures, then you need to load master data in Info objects(Characterstics) and for key figures you can load directly in the layout, once you save it , these values get saved back in Cube.
    Hope this helps

  • Can I reuse objects without Master data and load master data into it?

    Hai,
               I have a standard object that doesnot have Master data. Its already used somewhere else. It matches the name I want but I need to load some master data into it. Does resuing it in my catalogue and loading Master data into it hurt anything? Or should I create a new one?
    Thank you.

    Hi Visu,
    The same InfoObject can be included in more than one InfoObject catalog without any issue. Also loading master data would not hurt an existing InfoProviders where it is being used.
    Hope this helps...

  • Impact on transactional Loads if Master data is not loaded

    Scenario for your reference:
    The loads to ZPO_LINE from PC3 was failing for past 20 days from The fix was applied on April 21. 
    I need help to decide the effects of not loading ZPO_LINE for past 20 days. And create a detailed plan for data loads required.
    If the master data is not loaded for 20 days will it affect the transaction loads happened during those days?
    And how can i find out the impact and correct the transaction data if it does?
    Can any 1 help me with this?

    Hi,
    If i understand your scenario, you have a scenario where the Master data load has not been updated for the last 20days but, the transaction data was loaded without any interruption.
    In such a scenario, the Transactional loads will only be affected if there is some field which undergoes transformation after looking up on the master data.
    So, first load the master data and run the attrib change run process.
    After this, if the transaction data is in full update mode, then you dont need to do anything as data will be refreshed with correct values in the next load.
    If delta loads are there, you might need to performa  full repair.

  • How to Load the Master Data for custom defined Z infoobjects?

    Hi Gurus,
    This is the requirement.
    Some screen enhancements has to be made by adding  new Custom fields( like two text boxes,eg Name and city ) in such a way if we enter data into that text box,that data value for both of the Enhancements has to be stored in some table.If this data is a master data,then how would I pull this master data into BW.
    Please someone throw some light on this problem.
    Lets say a Screen is enhanced with NAME and CITY with text text boxes.Let the user enters the value for NAME and CITY.Let them be stored under two different tables ZTAB1 and ZTAB2.How would I load this master data into custom Defined  Z infoobjects ZNAME AND ZCITY in BW.
    Please help me out.
    Thanks is Advance,
    Regards

    you can by creating generic datasources on thoase tables with Full load or delta.
    if the number entries is less.. you can try full load...
    if it is more... along with required fields...put date also as one fields. which needs to get date of execution of program or date of uploading to Tables. this will be useful build Delta Mechanism.
    all the best.
