Generic Data source on VBFA Table

Dear Experts,
I would liike beuild a generic data source on VBFA table. Here i want to have all the fields of the Table.
Now my questions are.
1.I want to a Delta Update to BW, on want fields I should choose Delta to get all the changed records as well as the newly created records.
2. Do I need to build the Data source using a Function module.
3.Along with this I have a requirement to get the Sales Org, Company Code, Maetrial group information. How can I achieve this ( from which all tables I can get this information).
4. What is the frequncy of the table VBFA update.
5. generally what would be the number of Records for a Delta Update to BW.
Your suggestions are appreciated.
Regards,
Ganesh Thota.

  • Delta field not enabled for selection in  generic data source

    Hi
    I have created a generic data source for the table VBFA....and for the delta pick up i have put the delta option as CALDAY on the field ERDAT...and  i have  selected that field for the selection option. but after i made it  delta enabled the selection option got disabled.
    Now when i check the info package delta selection tab that date column is not apperaing.
    But when i have to run the info package for the first i dont want all the data as it has a huge set of data.
    I wanted to  take only this months data.
    So is there any option to be set to enable this selection in info package.
    please suggest.
    Regards
    Shilpa

    Hi there,
    That's the stardard behaviour. If you use delta based om ERDAT, that field won't be available for selecting.
    You could for example try to build a view over VBFA, and let the field ERDAT there and another field, for example ZERDAT (that is just another alias for ERDAT). Create the delta based onyour view over the field (ERDAT), but you can still control the restrictions over the extractore with your ZERDAT.
    I don't know if this is possible, this is only an assumption.
    Another option could be first to create an extractor based on the table VBFA but without delta, that field ERDAT would be available. Do your full data restricting it, and after that, change your datasource to use deltas based on ERDAT. It will be unavailable than, but since you've already loaded previous full data, you could than use your delta like it is. But here, remember, your deltas will bring new and change data based on ERDAT. If it brings delta based on changed data over ERDAT to a record that you didn't brought over your full (only some data), it will be incorrect records.
    Also just an assumption, did not try it.

    Hi,
    first go to ROOSFIELD and
    NEter your datasource name in oltpsource and check your field BPRME. what is its status in Selection.
    You have to make it 'X'.
    For that,You need to create an ABAP program in se38 and execute the attached code.
    update roosfield
    set selection = 'X'
    where oltpsource = V_PROD_TRADE
    and   field      = BPRME
    and   selection  = 'A'
    and   objvers    = 'A'.
    Hope i m clr.

  • Error generic data source for table VBAK in SAP R/3  7.01

    Hi
    When I was trying to create  generate data source(RSO2) from table VBAK. The system replies that
    Invalid extract structure template VBAK of Data Source ZSD_SALES
    You tried to generate an extract structure with the template structure VBAK. This operation failed, because the template structure quantity fields or currency fields, for example, field ZZLFAMT refer to a different table.
    Use the template structure to create a view or DDIC structure that does not contain the inadmissable fields.
    Regards
    Anand Reddy

    Hi,
    use 2lis_11_vahdr instead.
    But in addition, you need to create a view on vbak and the reference table/s of the keyfigure units, add the unit fields as well as all fields of vbak to the view and use the view for the generic datasource instead of the table.

    (I had done Steps one and 2 number of time by activating replicating the data source and so on, but still their is no change in it)
    3-> Then I had canceled that back ground job with the help of BASIS (as i feel that it is something going wrong).
    4-> I feel that their is some thing wrong in the Code of Extractor.

    Hi,
    Are your CURR fields refereded to a currency field of your structure?? Maybe the problem is that the field containing the currency is refered to other table/structure and it has to be one of your structure fields.
    Hope this helps,

  • Error while doing DELTA Extraction (generic data source)

    Hi BW Experts,
    In my R/3, I have a generic data source ZBUT_VW.
    It receives data from a View which is created based on couple tables.
    When I do full load to the corresponding ODS, it is successful.
    But after that I delete the ODS and created CUBE with DELTA
    I have Initialized delta.
    When I do DELTA extraction, it fails.
    The error “The ALE inbox of the SAP BW is identical to the ALE outbox of the source system
    and/or
    the maximum wait time for this request has not yet run out
    and/or
    the batch job in the source system has not yet ended.”
    I delete the initialization load and trying to do DELTA extraction again and it Fails.
    With the same error
    Please let me know how can I resolve this problem.
    URGENT
    gaurav

    I dont think it is possible to have to additive delta with creation date.
    Try a full load to cube to check if the extractor is working.

  • Error while testing Generic Data Source extraction

    I've created generic data source for Texts and Attributes in R/3 based on VIEW (Z table)
    I get  error "Error 6 in function module RSS_PROGRAM_GENERATE" while trying to test the data sources through RSO2
    I guess there can be a lot of reasons... Please name me anybody who knows them...
    thanx in advance

    Hi,
    Please Check the OSS note 328948 and it provides solution to same error what you have. Additionally you can have a look into this OSS note 705212 too.
    Syntax error in the generated extraction program Symptom
    You notice the error by one of the following symptoms:
    The loading of transaction data from an R/3 system terminates with a syntax error in the generated extraction program. The monitor displays the error messages:
    R3027 "Error & during the generation of the data transfer program"
    RSM340 "Error in the source system"
    The extraction within the extractor checker terminates with error message RJ028 "Error 6 in function module RSS_PROGRAM_GENERATE".The activation of transfer rules ends in BW with error message RG102 "Syntax error in GP$ERR$, row... (-> long text)" from the source system. Usually, the diagnosis in the long text of the error message is: "...could not be interpreted. Possible error causes: Incorrect notation or... "
    Other terms
    OLTP, extractor, data extraction, DataSource, Service API, SAPI,
    R3 027, R3 27, RSM 340, RJ 028, RJ 28
    Reason and Prerequisites
    The error only occurs in the source system, if this contains Basis Release 3.1I and Service API (SAPI) 3.0C Support Package 6. SAPI 3.0C Support Package 6 is contained, for example, in PI 2003.1 Support Package 7 (see attached composite SAP note 673002).
    Solution
    To correct the problem you need service API 3.0C Support Package 7 in the affected source system. The attached composite SAP note 704971 explains in which software components service API 3.0C is contained, and what the corresponding Support Packages of these components are.
    Alternatively, you can also copy the advance correction from the appendix.
    Hope it helps.

    I tried creating generic data source delta enabled on view of master data (/BI/M). But the problem I am facing now is master data contains quantity field as attribute and this field refers another table RSDKYF for unit. To be able to create data source on view / table no field should refer field in another table.
    Did anybody create delta for master data for further loading within BW or came across similar issue with key figures, please let me know the best procedure in this scenario? Appreciate your quick response.
    Regards,
    Madhav

    In your master data attribute have a date field which will be filled by the R/3 load as sy-datum - then create an export datasource and in the infopackage - give a selectoion for the date field as sy-datum and sy-datum -1..
    Not exactly a delta but then usually master data is not kept as delta because the volumes are usually less - you can achieve delta by this method...

  • Generic Data Source is calling multiple times in RSA3

    Hi experts,
    I have the requirement to get data from Generic Data Sources with function Module,
    after finishing the FM I have checked in extact checker(RSA)
    in the internal table I_T_DATA is displays 281 records,
    but in RSA3 it shows 112560 records, I found that the FM is calling multiple time by executing one time in RSA3.
    1.what would be the problem
    2.where is the porblem is it in FM coding or any other places to check.

    Hi Savita,
    I don't understand clearly from your reply regarding flow you transported and what all you transported.
    You need to first transport objects in R/3 and import them.
    Then transport Infoprovider, Datasource in BI assuming depenedent Infoare Infoobject, application component already transported.
    Then transport your Infosource, Update rule, Transfer rules, Infopackage.
    Hope you understood.

  • Extraction, Flat File, Generic Data Source, Delta Initialization

    Extraction, Flat File, Generic Data Source, Delta Initialization
    I have couple of questions regarding data extraction.
    1.     If you have Data Source a Flat File e.g. Excel file I know that you have to create Data Source at BW side. How do you upload updates, by selecting Delta Update when executing next Data Load? Do you ever u201Cconvertu201D this Excel file into Application Tables to become SAP Source 
    2.     Can you please give me example of situation where you had to create Generic Data Source? What is difference between Time Stamp, Calend. Day and Numeric Pointer. Which one is most common to select?
    3.     I read somewhere that Generic Data Source does not have Setup Table. I thought that you have to have Setup Table in order to load transaction Data otherwise you will lock the Application Tables. Where am I going wrong im my thinking please?
    4.     What are steps in terms of IP before, under and after Delta Initialization. I belive that you can do two ways:
    Full Update - Initialize Delta Process (without Data Transfer) u2013 Delta Update  or
    Initialize Delta Process (with Data Transfer) u2013 Delta Update
    Am I right? What is most common method and why?
    5.     If you want to add a filed in Data Source after 6 month using it, you want to do it without re-init Delta Queue. You add field in RSA6, then provide info for ABAP to populate new filed (info u2013 name of Data Source, Extract Structure, field added, name of Application Table which contains the field). How does it work now as there is no SetUp table it has been deleted after Initialisation? How does Delta Queue know that it is going to receive data which has been  expanded by one field or it may does not need to know at all?
    THANKSSSSSSSSSs

    Hi,
    1. If you have Data Source a Flat File e.g. Excel file I know that you have to create Data Source at BW side. How do you upload updates, by selecting Delta Update when executing next Data Load? Do you ever u201Cconvertu201D this Excel file into Application Tables to become SAP Source
    Once you create Datasource for A flat file extraction then it is file source system specific hence you cont change to Application table source Data source
    In info package you can change the source as application server instead of desktop no need to change the DS
    2. Can you please give me example of situation where you had to create Generic Data Source? What is difference between Time Stamp, Calend. Day and Numeric Pointer. Which one is most common to select?
    When we don't find any standard extractor then we can go for Generic(if i want information sales along with finance information in a data source then generally we dont get standard one hence we can go for generic DS)
    Check the below link for More about generic DS .
    http://wiki.sdn.sap.com/wiki/display/BI/Generic+Extraction
    for Delta capturing you can use
    Timestamp(if the table has time stamp filed  so it can stamp the last changed record in that table hence it is easy to get delta based on the time stamp)
    Calday- (If the table doesn't have the Timestamp filed then search for Calday where you can stamp the delta based on the date when documents are changed )
    Numericpointer : If the table doesn't above both then we go for this option where you can the numeric value change stamp )
    3. I read somewhere that Generic Data Source does not have Setup Table. I thought that you have to have Setup Table in order to load transaction Data otherwise you will lock the Application Tables. Where am I going wrong im my thinking please?
    Generic datasource nothing but we extracting data directly from the database table without any interface between the application/systems
    4. What are steps in terms of IP before, under and after Delta Initialization. I belive that you can do two ways:
    Full Update - Initialize Delta Process (without Data Transfer) u2013 Delta Update or
    Initialize Delta Process (with Data Transfer) u2013 Delta Update
    Am I right? What is most common method and why?
    Correct
    5. If you want to add a filed in Data Source after 6 month using it, you want to do it without re-init Delta Queue. You add field in RSA6, then provide info for ABAP to populate new filed (info u2013 name of Data Source, Extract Structure, field added, name of Application Table which contains the field). How does it work now as there is no SetUp table it has been deleted after Initialisation? How does Delta Queue know that it is going to receive data which has been expanded by one field or it may does not need to know at all?
    Once you add the new field to structure(DS) you will get the data as on date onwards not historical data hence what is the concept of setup table  ( delta records come from the Delta Que not from the setup table )
    If you want histaric data to new field then you need to setp table deletion ...etc...
    Hope it is clear..
