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
regards,
Ramakrishna

Hi Ramakrishna,
For doing a delta on a generic extractor you will have to set up any one of the following type of the field as delta attribute and on the basis of this delta records will be extracted.
- Time Stamp
- Calendar day
- Numerical Pointer (i.e. Document Number)
You can monitor your delta queue via RSA7 transaction.
Also For delta you will have to do Init load first.
Hope that helps.
Regards.

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.

Hi,
The statement RAISE NO_MORE_DATA 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.
examples wud be vry useful

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:
        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.
        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.
        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.
        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.

Generic Extraction-example

hello EXPERTS
I am trying to give one presentation about 'Generic Extraction using View'...I know how to explain the process.But as I donot have project experience,I have never worked with Generic Extraction.
Can any one give an example where they used generic extraction(by view) on SAP standard tables.Its enough if you can mention the fields you used and from which tables you took these fields?
Thanks
S

Hi,
Processing steps for creating the Generic Datasource by useing View:
1.Goto RSo2.
Datasource can be created for
a). Transaction Data
b). Master data Attributes
c). Master data Text
2.Specify Application component(SD/MM..)
3.There are three extraction methods to fill datasource.
    i).Transparent table or Database view
    ii).InfoSets of the SAP query
    iii).Using a Function Module
4.Select extraction method extracts the data from a transparent table or database view.
5.select Extraction from View, then we have to create the View.
   a).specify the view name.
   b).choose the view type (Database view) from bellow mentioned views.
      Database view.
      projection view.
      maintainance view.
      help view.
6. Specify Tables and Join Conditions and define view fields.
7. Assign View to Datasource
8. Once you specify view in Data source, the extract structure willgenerate.
9. then select the filds in selection column.
10. Specify Delta-Specific Field and type.
11. Specify Safety Interval and Delta Type and select Save button.
12. Testing the Generic extraction.
Select Datasource option from menu bar-->select Test Extraction or you can check in RSA3.

Suman.

Regarding generic extractors

hi gurus help me .
in ge extraction we have delta loads as . 1. time stamp.2.calenday . 3. numericpointer.
can u provide details in which situations we use this parameters .and what exactly these are uesd for induvidually
provide me with an example please
advance thanks

HI,
0calday -- is to be run only once a day that to at the end of the day and with a range of 5 min. Numeric Pointer -- is to be used for the tables where it allows only appending of records ana no change .. eg: CATSDB HRtime managent table .
Timestamp: using this you can always delta as many times as possible with a upeprlimit .

Reg Generic Extraction

Hi Gurus,
Can any one explain me about generic extraction like,
1) when we go for Generic extraction
2) what is the business scenario
3) generic delta
Please explain me with step by step by choosing some data fields as example for this. One request, plz don't send sap help file as i have it. If any one have screen shots for this plz send me.
Thanks in advance.
Regards
K.M.Reddy

hi,
we go for generic extraxctor when standard cube or datasource do not suite the
requirement.
for eg in satandard sd datasource donot have the field we require then we
go for generic datasource.
if standard datasource do not have shipping point field in datasource then we
can either append the structure or go for generic datasource.
for generic delta refer link.

Generic extraction loading and performances issues

hi,
any one can give the details about the generic extraction loading as well as performance issues.
advance thanks
regards
praveen

Hi,
when there is no suitable business content datasource we go for creating generic data source.
by using generic data source we can extract data present in single or multiple tables.
If the data is present in the single table we go for generic data source extracting from table.
If the data that is to be extracted is present in multiple tables and the relation between the tables is one to one and if there is a common field in both the tables we create a view on these tables and create a generic data source extracting from view.
if you want to extract data from different tables and there is no common field we create a info set on these tables and create a generic datasource extracting from query.
if you want to extarc the data from different tables and the relation is one to many or many to many we create a generic data source from function module.
If we extarct from function module ,at run time it has to execute the code and brings the data to BW.so it degrades the loading performance.

Customer and Generic extraction difference ?

Hi ya,
Could any body tell me the difference between the customer and Generic extractions.what are the extraction steps?
Regards.

Hi,
In Generic extraction we have to fetch the data from table/view/funtion module.T.code RSO2.
Replicate the data source in bw and send into data target through ods(recommandable).
In customized extraction sap provided LIS,LO-COCKPIT,CO-PA,FI-SL etc,in these sap provides extract stuructures.From the extract structures we have to fetch the data and replicate the data into bw and push into the data targets.
with regards,

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)
