  • When we go for Views and Function Modules for Generic Extraction

    Hi Experts,
    Can you please explain when we go for extracting the data using Views and when we got using Function Modules using Generic Extraction from R/3 system to BW with examples. And also can you explain when we go for delta for the above both scenarios.
    Thanks for you help in advance

    Hi,
    Scenario for Extarction using FM
    Imagine the scenario where you need to extract data from
    tables having no common field between them and thereby preventing you from creating a view on top of those tables..
    Or simply consider tables that are highly unrelatd in terms of fields, but you have a requiremnt to extract data from them.
    Also Refer.

    How to do basic LO extraction for SAP-R3-BW
    1. Go to transaction code RSA3 and see if any data is available related to your DataSource. If data is there in RSA3 then go to transaction code LBWG (Delete Setup data) and delete the data by entering the application name.
    2. Go to transaction SBIW --> Settings for Application Specific Datasource --> Logistics --> Managing extract structures --> Initialization --> Filling the Setup table --> Application specific setup of statistical data --> perform setup (relevant application)
    3. In OLI*** (for example OLI7BW for Statistical setup for old documents : Orders) give the name of the run and execute. Now all the available records from R/3 will be loaded to setup tables.
    4. Go to transaction RSA3 and check the data.
    5. Go to transaction LBWE and make sure the update mode for the corresponding DataSource is serialized V3 update.
    6. Go to BW system and create infopackage and under the update tab select the initialize delta process. And schedule the package. Now all the data available in the setup tables are now loaded into the data target.
    7.Now for the delta records go to LBWE in R/3 and change the update mode for the corresponding DataSource to Direct/Queue delta. By doing this record will bypass SM13 and directly go to RSA7. Go to transaction code RSA7 there you can see green light # Once the new records are added immediately you can see the record in RSA7.
    8.Go to BW system and create a new infopackage for delta loads. Double click on new infopackage. Under update tab you can see the delta update radio button.
    9.Now you can go to your data target and see the delta record.
    find your scenario and find what data sources do you need on R3 side and ensure they are active as well:
    http://help.sap.com/saphelp_nw04/helpdata/en/37/5fb13cd0500255e10000000a114084/frameset.htm
    find your scenario -> data sources -> go to R3 -> sbiw and activate required data source
    replicate data sources in BW:
    RSA1 -> source systems -> right click on your source system -> replicate
    then activate your BC:
    service.sap.com/bi -> BI Business Content -> General Information -> SAP BW Business Content - Activation
    and execute infopackage (it should be delivered with BC)

    Hi,
    These 2 below links may be helpful,
    <u>GENERIC DATA EXTRACTION USING FUNCTION MODULE</u>
    <u>Difference between Generic Extraction and Enhancement of existing Extractor</u>
    1)Go to RSA6 and find the data source you need to enhance.--> Display
    2)Double click on the Extract structure.
    3)Now click on the append structure button to add the required field on to the existing structure.
    4) add your required fields with ZZ appended to your field.
    5) Save & Activate the append structure. Then go back and make sure you activate the extract structure also.
    6) Now again go back to RSA6 and select your Data Source. But this time go to change Data Source to remove the hide option to the enhanced fields. By default they’ll be in hide mode. If you don’t remove the hide field then this field will not be seen in BW side.
    7) Now go to SE38 to write the logic to populate the data into the enhanced field. Program name to write the logic is ZXRSAU01.
    8) Check + Save + Activate.
    9) Check in RSA3 if data is populated as per your requirement.
    10) Replicate your Data Source.
    11) Now go to Data Source/ Trans. Structure screen. Now you can see the enhanced field on the right hand side.Enhancements:

  • Scenarios for Generic extraction

    Hello experts ,
    Please give me some scenarios where we will go for the extraction using
    function module,
    infoset query,
    View.
    Thanks in advance,
    pragya.

    Hi Pragya,
    Generic extractors are of 3 types:
    1. Based on table/view
    2. Based on Infoset Query
    3. Based on Function module
    <i>In some cases Business Content will not give your required data sources , In such scenarios you need to develop your own data sources ( Views / Function modules ) , Then you can bring that data source to BW and use that .
    if you can't find the suitable business content data source then you have to create
    your own data source ( Generic )
    or enhance the given data source.</i>
    <b>Need for customized generic extractor</b>
    Business Content may not have a suitable
    Data Source for your application.
    Business Content may require additional enhancements that need data that is not supplied by SAP BW.
    The application may not have its own generic data extraction method.
    We have used our own custom programs to populate tables in SAP system.
    Please see link below

  • About Generic Extraction

    Hi all,
                  I would like to have some links r docs to mail about DB view extraction. I am stuck in it. I would like to know it from  how to create a view and till how do i recognize a delta field in the given 2 tables.
    my mail ID is [email protected]
    Thanks and regards.

    hi pradeep,
      Maintaining Generic DataSources 
    Use
    Independently of application, you can create and maintain generic DataSources for transaction data, master data attributes or texts from any kinds of transparent tables, database views, InfoSets of the SAP query or using a function module. As a result, you can make use of the generic extraction of data.
    Procedure
    Creating a Generic DataSource
           1.      Select the DataSource type and give it a technical name.
           2.      Choose Create.
    The creating a generic DataSource screen appears.
           3.      Choose an application component to which the DataSource is to be assigned.
           4.      Enter the descriptive texts. You can choose any text.
           5.      Choose from which datasets the generic DataSource is to be filled.
                                a.      Choose Extraction from View, if you want to extract data from a transparent table or a database view. Enter the name of the table or the database view.
    After generation, you get a DataSource whose extract structure is congruent with the database view or the transparent table view.
    For more information about creating and maintaining database views and tables, see the ABAP Dictionary Documentation.
                                b.      Choose Extraction from Query, if you want to use a SAP query InfoSet as the data source. Select the required InfoSet from the InfoSet catalog.
    Notes on Extraction Using SAP Query
    After generation, you now have a DataSource whose extract structure matches the InfoSet.
    For more information about maintaining the InfoSet, see the System Administration documentation.
                                c.      Choose Extraction using FM, if you want to extract data using a function module. Enter the function module and extract structure.
    The data must be transferred by the function module in an interface table E_T_DATA.
    Interface Description and Extraction Process Flow
    For information about the function library, see the ABAP Workbench: Tools documentation.
                                d.      With texts, you also have the option of extraction from domain fixed values.
           6.      Maintain the settings for delta transfer where appropriate.
           7.      Choose Save.
    When extracting, look at SAP Query: Assigning to a User Group.
    Note when extracting from a transparent table or view:
    If the extract structure contains a key figure field, that references to a unit of measure or currency unit field, this unit field must appear in the same extract structure as the key figure field.
    A screen appears in which you can edit the fields of the extract structure.
           8.      Editing the DataSource:
    &#61601;        Selection
    When scheduling a data  request in the BW Scheduler, you can enter the selection criteria for the data transfer. For example, you may want to determine that data requests are only to apply to data from the previous month.
    If you set the Selection indicator for a field within the extract structure, the data for this field is transferred in correspondence with the selection criteria in the scheduler.
    &#61601;        Hide field
    You should set this indicator to exclude an extract structure field from the data transfer. As a result of your action, the field is no longer made available in BW when setting the transfer rules and generating the transfer structure.
    &#61601;        Inversion
    Reverse postings are possible for customer-defined key figures. For this reason, inversion is only possible for certain transaction data DataSources. These include DataSources that have a field that is indicated as an inversion field, for example, the field update mode in the DataSource 0FI_AP_3. If this field has a value, then the data records are interpreted as reverse records in BW.
    Set the Inversion indicator if you want to carry out a reverse posting for a customer-defined field (key figure). The value of the key figure is then transferred in inverted form (multiplied by –1) into BW.
    &#61601;        Field only known in exit
    You can enhance data by extending the extract structure for a DataSource using fields in append structures.
    The indicator Field only known in Exit is set for fields of an append structure. In other words, by default these fields are not passed onto the extractor from the field list and selection table.
    Deselect the indicator Field Only Known in Exit to enable the Service API to pass on the append structure field to the extractor together with the fields of the delivered extract structures in the field list as well as in the selection table.
    9. Choose DataSource ® Generate.
    The DataSource is now saved in the source system.
    Maintaining Generic DataSources
    •        Change the DataSource
    To change a generic DataSource, in the initial screen of DataSource maintenance, enter the name of the DataSource and choose Change.
    You can change the assignment of a DataSource to an application component as well as the texts of a DataSource. Double-clicking on the name of the table, view, InfoSet or extract structure takes you to the appropriate maintenance screen. Here you can make changes required to add new fields. You can fully swap transparent tables and database views, but not InfoSets. If you return to the DataSource maintenance and choose Create, the screen for editing a DataSource appears. To save the DataSource in the SAP source system, choose DataSource  ® Generate.
    If you want to test extraction in the source system independently of a BW system, choose DataSource  ®  Test Extraction.
    •        Delta DataSource
    In the Change Generic DataSource screen, you can delete any DataSources that are no longer relevant. If you are extracting data from an InfoSet, delete the associated query. If you want to delete a DataSource, this must not be connected to a BW system.
    For more information about extracting using SAP Query, see Extraction using the SAP Query.

    Gentlemen,
    Please be aware, enhancing GL, AP and AR datasource are completely different then enhanceing LIS datasource or most other datasources. You cannot (the last time I knew) populated fields in the User Exit for GL, AP and AR, to enhance these, you need to follow this OSS message to the "t".
    /Steve
    OSS message: 410799.
    See below OSS message:
    Symptom
    The extraction structures for datasources 0FI_GL_4 (General ledger: line item), 0FI_AP_4 (vendors: line item) and 0FI_AR_4 (customers: line item) should be enhanced by additional fields.
    By doing so, additional information can be transferred for each line item from the R/3 system to the BW system.
    Other terms
    (for example, customer or vendor master data).
    Customer enhancement, extraction structure, extraction, FI_GL, general ledger, FI-AP creditors, FIAP vendors, line items, datasources/infosources:
    0FI_GL_4, 0FI_AP_4, 0FI_AR_4
    Reason and Prerequisites
    There is missing documentation on the customer enhancement of datasources/infosources 0FI_GL_4, 0FI_AP_4, 0FI_AR_4
    Solution
    In the R/3 source system, the following structures participate in the extraction of line items from the applications FI-GL, FI-AP, FI-AR:
    Applic.  datasource read structure extractionsstr.  customer-INCLUDE
    FI-GL 0FI_GL_4 BSIS DTFIGL_4 CI_BSIS
    FI-AP 0FI_AP_4 BSIK DTFIAP_3 CI_BSIK
    FI-AR 0FI_AR_4 BSID DTFIAR_3 CI_BSID
    The data sources provide the fields of the assigned extraction structure from the R/3 source system to the BW system.
    These extraction structures can be enhanced by creating the respective customer include in the data dictionary of the R/3 source system. After creating this, generate the customer include in the data dictionary.
    The fields for the customer enhancement in the customer include has to be filled during the data extraction in the R/3 source system. In doing so, two cases arise:
    1. All the fields of the customer enhancement in the customer include are contained in the read structure (see the table above).
               Then no additional action is required. The fields of the customer enhancement are filled automatically by the datasource from the assigned read structure via "move-corresponding".
               Example:
               The extraction structure DTFIGL_4 for datasource 0FI_GL_4 (General ledger: line item) should be enhanced by the VALUT (value date) field.
               To do this, create structure CI_BSIS in the data dictionary of the R/3 source system and include the VALUT field in it. The data dictionary in the R/3 source system shows that the VALUT field is contained in the read structure of the datasource (table BSIS). For that reason the VALUT field is automatically filled by datasource 0FI_GL_4.
               ATTENTION:
               By using Note 430303 you can enhance DataSource 0FI_GL_4 by all fields from table BSEG (instead of BSIS); then the fields are filled automatically in the extractor.
    2. Fields of the customer enhancement in the customer include are not contained in the read structure (see the table above).
                In this case you have to program a function module to fill the field of the customer enhancement. To do this, there is a Business Transaction Event available (open FI interface for process 00005021). Create any function module you like and use function module SAMPLE_PROCESS_00005021 as a template for the interface (input parameter, changing parameter).
               Interface of function module SAMPLE_PROCESS_00005021:
                Input-parameter I_OLTPSOURCE: datasource that is currently extracting data from the R/3 source system.
                Changing-Parameter C_STRUCTURE: Extraction structure of the data source currently extracting including fields from the assigned customer include. When you call this customer defined function module, all the fields of the extract structure are transferred filled.
               Check whether the type pool SBIWA is declared in the TOP include of the function group.
    If not, add it with the statement TYPE-POOLS: SBIWA.
               Then maintain table TPS31 with Transaction SM30. Create the following entry:
               PROCS LAND APPLK FUNCT
               00005021 <fname>
               <fname> stands for the customer defined function module.
                By doing so, the function module you defined is called for each extracted record. Note that in this case the performance of the extraction may be reduced significantly regardless of the table read and the complexity of the programmed logic.
               Example:
               You want to enhance the extraction structure DTFIAR_3 for datasource 0FI_AR_4 (customers: line item) by the ORT01 (city) field from the customer master record.
                To do this, create structure CI_BSID in data dictionary of the R/3 source system and include the ORT01 field in that. The data dictionary in the R/3 source system displays that the ORT01 field is NOT contained in the read structure of datasource 0FI_AR_4 (Table BSID).
                Therefore you have to program a function module that reads the customer master in the R/3 system (table KANN1) and fills the ORT01 field of the customer enhancement. In the changing parameter C_STRUCTURE the filled fields of the extraction structure DTFIAR_3 are available to you. With the KUNNR field of extraction structure DTFIAR_3, you can select the respective master data record from table KNA1 and determine field ORT01 of the customer enhancement.
    After you create the customer include in the R/3 source system you have to postprocess the accompanying datasource with Transaction RSA6. Select the application component according to the above table and change the datasource that fits the customer include. The "Hide fields" flag should be removed in the field list for the fields of the customer include. Then save the field list.
    If the fields of the customer include is not displayed in Transaction RSA6, refer to note 415530.
    Then you have to replicate the enhanced datasource again in your BW system. Select the infosource that belongs to the datasource in the Administration Workbench of your BW system (Transaction RSA1 --> Modeling --> InfoSources) and replicate the datasource from the R/3 source system (right mouse button on the appropriate R/3 source system for the infosource).
    You have to create the appropriate infoobjects for the fields of the customer enhancement in the BW system if they do not already exist.
    Then in your BW system make sure that the accompanying infosources (communication structures and transfer rules) and data targets (ODS objects and InfoCubes) have been extended by the new field or infoobject. All the objects which have been changed in the BW system must also be activated there.

  • Generic extractions

    Can anyone give me a screen shots of how to do generic extractions by extraction by view/table & also how to add fields of different tables in a view method.pls suggest.
    Thanks in Advance.

    Dear Suresh,
    Generic Data Source is created whenever the SAP Content Data source doesnu2019t support our requirement And then we can create a data source with respect to our requirement.
    There are two ways you can enter into the creation screen of generic data source:
    1)     By entering SBIW as the T-code.
    Expand the Generic Data sources icon and press on the clock symbol (IMG activity)
    Or      Instead of all the above steps you can simply use T-code: RSO2
    Now you have the option to create, change or display a Data source for transaction Data, Master Data attributes or Texts.
    Give a Proper technical name of the Data Source you want to create and press create
    Now select the Application Component in which you want to create the datasource
    After selecting the application component. Fill the Description fields. And now select the mode of extraction you want to do like
    1)     Extraction from View/Table
    2)     Extraction from SAP Query
    3)     Extraction by function module
    And once you give the name of the view/table from where you want to extract. Press Generic delta button at the top.
    Here we have three options for delta updation:
    Time Stamp:   If we want to update change in the records with respect to the time interval then this option is selected.
    Calend. Day:   If we want to update change in the records with respect to day to day basis then this option is selected.
    Numeric Pointer:  If we want to update in case of record which is completely new with respect to Field name then we use this option.
    And we have got some settings like:
    Safety Interval upper limit:
    This field is used by Data Sources that determine their delta generically using a repetitively-increasing field in the extract structure.
    The field contains the discrepancy between the current maximum when the delta or delta init extraction took place and the data that has actually been read.
    Leaving the value blank increases the risk that the system could not extract records arising during extraction.
    Example: A time stamp is used to determine the delta. The time stamp that was last read is 12:00:00. The next delta extraction begins at 12:30:00. In this case, the selection interval is 12:00:00 to 12:30:00. At the end of extraction, the pointer is set to 12:30:00.
    A record - for example, a document- is created at 12:25 but not saved until 12:35. It is not contained in the extracted data but, because of its time stamp, is not extracted the next time either.
    For this reason, the safety margin between read and transferred data must always be larger than the maximum length of time that it takes to create a record for this DataSource (with a time stamp delta), or it must display an interval that is sufficiently large (for determining delta using a serial number).
    Safety Interval Lower Limit
    This field contains the value taken from the highest value of the previous delta extraction to determine the lowest value of the time stamp for the next delta extraction.
    For example: A time stamp is used to determine a delta. The extracted data is master data: The system only transfers after-images that overwrite the status in the BW. Therefore, a record can be extracted into the BW for such data without any problems.
    Taking this into account, the current time stamp can always be used as the upper limit when extracting: The lower limit of the next extraction is not seamlessly joined to the upper limit of the last extraction. Instead, its value is the same as this upper limit minus a safety margin. This safety margin needs to be big enough to contain all values in the extraction which already had a time stamp when the last extraction was carried out but which were not read. Not surprisingly, records can be transferred twice. However, for the reasons above, this is unavoidable.
    Data Source Is Real-Time Enabled
    The 'real time enabled' indicator determines whether a delta-enabled Data Source can be used as a supplier of data for a real-time daemon.
    And there are two options provided like
    1)     New Status for changed records:
    If you select this option each record to be loaded delivers the new status for the key figures          and characteristics. DataSources with this delta type can write to ODS objects or master data tables.
    2)     Additive Delta:
    The key figures for extracted data are added up in BW. Data Sources with this delta type can supply data to ODS objects and Info Cubes.
    After giving the required selections of all the above options save the data source.
    Then you will get a screen where you have options like:
    1)     Selection:
    Check it when you want to select the range of the values to be picked from this field. Once we select this field, it will be available in the infopackage under the Data Selection tab for selecting the range.
    2)      Hide Field:
    Check it when you donu2019t want this field to be extracted.
    3)      Inversion:
    This will give the negative value of the field.
    4)       Field Only:
    If a field is required only for certain calculation purpose and not for extraction then we can check this option.
    Once we give all the above selections, save it and replicate the Data source in BW.

  • Urgent: Problems in Generic Extraction by Function Module

    Hi BW Gurus,
    I am new to SDN and also new to generic extraction using function module. My requirement is to extract long text(142 char) from CRM to BW as the text is not stored in database table I used function module read_text with in another ZXXX function module copy of (RSAX_BIW_GET_DATA_SIMPLE). In my extract structure I used GUID(char,32), Langu, long text(142 char) and 2 placeholders. Text can be extracted by passing STXH table fields(Tdname, Tdid, Tdobject, Tdspars) to read_text as parameters and i also need to use CRMD_ORDERADM_H field GUID(32 char) to compare 1st 32 chars of tdname(70 char) with Guid to select Guids and loop thru this Guids and for each Guid i need to append lines of text to e_t_data but as i donot know ABAP i unable to write the code for this. Through my friends help i wrote code when i check in RSA3 it is displaying the text but when i replicate into BW and load into data target in monitor the status is red with records initially but afterwards it will be red status again with 0 from 0 records for initial load again.when i check on job logs the errors i have are:
    The background job has created a job log file of 2Gb size and it is currently on a infinite loop writing entries into the SAP System Log that it cannot write to the Job log file due to “Error 22 for write/read access to a file” this is because of the datasource i have created. Please find my Function module and if anyone would please correct FM and send me that will be really great.I appreciate it in advance.
    MY Function Module is:

    Hi,
    The statement <b>RAISE NO_MORE_DATA</b> should be active (uncommented) in your code. Otherwise, the infinte loop occurs.

  • Generic Extraction (or) How to use table in R/3 system as datasource in BW?

    Hi all,
    Hope all are having a great day
    Can any1 tell me the steps, for Generic Extraction.
    It will be very helpful, if the steps are as much as simpler as posible.
    I know to create a simple cube in BW.
    I have this much knowledge, depending on this can any1 tell me the steps for Generic Extraction from R/3.

    hi,
    Maintaining Generic DataSources 
    Use
    Independently of application, you can create and maintain generic DataSources for transaction data, master data attributes or texts from any kinds of transparent tables, database views, InfoSets of the SAP query or using a function module. As a result, you can make use of the generic extraction of data.
    Procedure
    Creating a Generic DataSource(RSO2)
           1.      Select the DataSource type and give it a technical name.
           2.      Choose Create.
    The creating a generic DataSource screen appears.
           3.      Choose an application component to which the DataSource is to be assigned.
           4.      Enter the descriptive texts. You can choose any text.
           5.      Choose from which datasets the generic DataSource is to be filled.
                                a.      Choose Extraction from View, if you want to extract data from a transparent table or a database view. Enter the name of the table or the database view.
    After generation, you get a DataSource whose extract structure is congruent with the database view or the transparent table view.
    For more information about creating and maintaining database views and tables, see the ABAP Dictionary Documentation.
                                b.      Choose Extraction from Query, if you want to use a SAP query InfoSet as the data source. Select the required InfoSet from the InfoSet catalog.
    Notes on Extraction Using SAP Query
    After generation, you now have a DataSource whose extract structure matches the InfoSet.
    For more information about maintaining the InfoSet, see the System Administration documentation.
                                c.      Choose Extraction using FM, if you want to extract data using a function module. Enter the function module and extract structure.
    The data must be transferred by the function module in an interface table E_T_DATA.
    Interface Description and Extraction Process Flow
    For information about the function library, see the ABAP Workbench: Tools documentation.
                                d.      With texts, you also have the option of extraction from domain fixed values.
           6.      Maintain the settings for delta transfer where appropriate.
           7.      Choose Save.
    When extracting, look at SAP Query: Assigning to a User Group.
    Note when extracting from a transparent table or view:
    If the extract structure contains a key figure field, that references to a unit of measure or currency unit field, this unit field must appear in the same extract structure as the key figure field.
    A screen appears in which you can edit the fields of the extract structure.
           8.      Editing the DataSource:
    &#61601;        Selection
    When scheduling a data  request in the BW Scheduler, you can enter the selection criteria for the data transfer. For example, you may want to determine that data requests are only to apply to data from the previous month.
    If you set the Selection indicator for a field within the extract structure, the data for this field is transferred in correspondence with the selection criteria in the scheduler.
    &#61601;        Hide field
    You should set this indicator to exclude an extract structure field from the data transfer. As a result of your action, the field is no longer made available in BW when setting the transfer rules and generating the transfer structure.
    &#61601;        Inversion
    Reverse postings are possible for customer-defined key figures. For this reason, inversion is only possible for certain transaction data DataSources. These include DataSources that have a field that is indicated as an inversion field, for example, the field update mode in the DataSource 0FI_AP_3. If this field has a value, then the data records are interpreted as reverse records in BW.
    Set the Inversion indicator if you want to carry out a reverse posting for a customer-defined field (key figure). The value of the key figure is then transferred in inverted form (multiplied by –1) into BW.
    &#61601;        Field only known in exit
    You can enhance data by extending the extract structure for a DataSource using fields in append structures.
    The indicator Field only known in Exit is set for fields of an append structure. In other words, by default these fields are not passed onto the extractor from the field list and selection table.
    Deselect the indicator Field Only Known in Exit to enable the Service API to pass on the append structure field to the extractor together with the fields of the delivered extract structures in the field list as well as in the selection table.
    9. Choose DataSource ® Generate.
    The DataSource is now saved in the source system.
    Maintaining Generic DataSources
    •        Change the DataSource
    To change a generic DataSource, in the initial screen of DataSource maintenance, enter the name of the DataSource and choose Change.
    You can change the assignment of a DataSource to an application component as well as the texts of a DataSource. Double-clicking on the name of the table, view, InfoSet or extract structure takes you to the appropriate maintenance screen. Here you can make changes required to add new fields. You can fully swap transparent tables and database views, but not InfoSets. If you return to the DataSource maintenance and choose Create, the screen for editing a DataSource appears. To save the DataSource in the SAP source system, choose DataSource  ® Generate.
    If you want to test extraction in the source system independently of a BW system, choose DataSource  ®  Test Extraction.
    •        Delta DataSource
    In the Change Generic DataSource screen, you can delete any DataSources that are no longer relevant. If you are extracting data from an InfoSet, delete the associated query. If you want to delete a DataSource, this must not be connected to a BW system.
    For more information about extracting using SAP Query, see Extraction using the SAP Query.
    hope this helps.

  • BC in Generic extraction

    Hi Gurus
    Can we use BC in generic extraction ? How?

    KR
    In this case we called as enhancement of the standard datasource. In your example you need 17 fields and you found one standard datasource which is taking care of your fourteen fields. For other three fields you will do the enhancement i.e you will add these three custom fields in the append structure of standard datasource and you will populate these three fields user exit.
    Please see this attachment on How to Enhance standard Data source.

  • Regarding Generic Extraction

    Hi Experts,
    I m new to SAP BW, I need a information regarding Generic Extraction as the senario is follows.
    I created a table with fields,
    Customer Id (PK), name, age ***, address
    and i maintained five records in it.
    i created a generic master data attributes data source using above table
    i replicated the data source in bw and run the full update and it is succussful.
    Now my requirement is to add 5 more records in the above table and i hav to get those records in bw using delta update.
    So, can any one can explain how to maintain delta for that generic datasource and how to run delta update in step-by-step process
