View creation fr generic extraction

Hai Experts,
when we are create view from two different table ,wht is the crieteria that should satisfy between tables..... and at the time of datasource creation which type we need to select (master/trans)..as i found both master and transaction field in one table
Can any one send the step by step process to create view..
I have one more scenario ie .,i need to create a datasource from tables which belong to diff applications and their primary key is different ,can any one tell me how to create a datasource using function module,step by step process..
thnks in advance,
Regards,
Suri

Reg View creation in Generic

Hi SDN,
Im trying to create Generic Data source of View Method. I wanted to create View on BSID ( Closed Customer Invoices) and BSAD ( Open Customer invoices) Tables, But while creating its giving error as "THERE IS NO RELATION BETWEEN THE TABLES" I want to know how to create Relation Between the tables. Both BSID & BSAD are standard tables, so we cant make any changes.
Please let me know the procedure to bulid Rlation between the tables.
Regards

Hi Siva,
You have to give relation between these two tables in tab "Table/Join Conditions".

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
Rohith

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.

When to go for generic extraction using view and infoset query?

Hi,
Can anyone clarify me when we should go for generic extraction using view and when we should go for generic extraction using infoset query....
Also what is the difference between view and infoset?
I tried but could not find out....
Regards,
Kalyani.

Hi Kalyani,
We normally go for View or infoset when the data to be fetched in BW is distributed in different tables in SAP R/3.
Had the data been available in one table we can easily build our datasource on that table but if there are more tables then its not possible to do it without Views or Infosets. You can use Function Modules to build your datasource in case it involves complex logic to figure out the data from various tables.
Depending upon the table relationships we create view and include various fields from these tables in that view. Same is with the Infosets, you can have more flexible options like Outer Join, left outer Join etc.

Give me details about differrent views in generic extraction give details

give me details about differrent views in generic extraction give details such as database view, projection view, help view, etc please give detail

Dear Deba,
Projection view - Just retrieves some fields from a single table.
Help View - This is used for search help.
Database View - This is inner join view of one or more tables
Maintenance View - Helps in creating maintaining data of the application object. The data can be distributed among several tables
Data Base View:
A database view is defined in the ABAP Dictionary and automatically created on the database during
activation. Accesses to a database view are passed directly to the database from the database interface.
The database software performs the data selection.
If the definition of a database view is changed in the ABAP Dictionary, the view created on the database
must be adjusted to this change. Since a view does not contain any data, this adjustment is made by
deleting the old view definition and creating the view again in the ABAP Dictionary with its new definition.
The maintenance status defines whether you can only read with the view or whether you can also write
with it. If a database view was defined with more than one table, this view must be read only.
The data read with a database view can be buffered. View data is buffered analogously to tables. The
technical settings of a database view control whether the view data may be buffered and how this should
be done. The same settings (buffering types) can be used here as for table buffering. The buffered view
data is invalidated when the data in one of the base tables of the view changes.
Maintainance View:
Data that is distributed on more than one table often forms a logical unit, called an application object.
You should be able to display, change and create the data of such an application object together. Users
usually are not interested in the technical implementation of the application object, such as the distribution of the data on several tables.
You can maintain complex application objects in a simple way using a maintenance view. The data is
automatically distributed on the underlying database tables.
All the tables used in a maintenance view must be linked with a foreign key. This means that the join
conditions are always derived from the foreign key in the maintenance view. You cannot enter the join
conditions directly as in a database view.
A maintenance interface with which the data of the view can be displayed, changed and created must be
generated from the definition of a maintenance view in the ABAP Dictionary.
When the maintenance interface is created, function modules that distribute the data maintained with the
view on the underlying tables are automatically generated.
The maintenance interface is generated with the Transaction Generate Table View (Transaction SE54)
or from the view maintenance screen with Environment -> Tab.maint.generator.
Database views implement an inner join. You only get those records which have an entry in all the tables
included in the view.
Maintenance views implement an outer join.
Help View:
A help view is defined analogously to a maintenance view. Help views can only be used as selection
methods in search helps. Since the R/3 System cannot pass the selection directly to the database using
a help view, it must generate its own access routines. The database view should therefore be used as
selection method in preference to the help view.

What is the disadvantage with views in generic extraction?

hi
what is the disadvantage with views in generic extraction?
thanks in advance,
srinivas.

Hi ,
What is disadvantage of generic extraction ? 
If i am asking this what you will say ......You have only less points to say if any one ask you like this .
Similarly Generic extraction based on view has many advantegs It was given to extrct data when standard business content data source is not available .
But we know Views can be created when the table you need to extract data has Primary Foreign key relation .So if you need to extarct data from many tables with no relation between them then you cannot use view .
But if you need to extract data from tables that have complex relation ,Then you need to go for Function Module extration and write some ABAP code and using SQL ststements you fetch data from tables based on thier key fields and finally get the desired data by your coding logic .

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.

Generic extraction

Hi,
in generic extraction in which scenarios you extract data from table,view,infoset query,FM
sridhar

Transparent Table
If you're wishing to create a generic DataSource based on a single Transparent Table in the source R3/ECC system, then using that table as the source for your generic DataSource would be appropriate because it will expose all of the columns in that table to your generic extraction structure. There is one exception to this and that is, if you have more than one date field (e.g. Created On and Changed On dates) that you're going to use for generic delta. Pool/Cluster tables and structures wouldn't be allowable for this type of generic DataSource setup.
View on Transparent Tables
If your requirement is to create a generic DataSource based on multiple Transparent Tables in your source R3/ECC system, then a view would be appropriate. You can either use SAP delivered views in the source R3/ECC environment or create a custom view. The same exceptions (generic delta on more than one date field, pool/cluster tables and structures).
Function Module
A custom Function Module can be coded for the extraction of data for a generic DataSource. This type would be appropiate if you're extracting data from pool/cluster tables or structures. Another use for a Function Module as the source for a generic DataSource would be if you're going to use more than one data field for a generic delta. Finally, a Function Module would be used if there is some transformational-type logic required to be done on the extracted data before it is passed to BW.
InfoSet Query
An InfoSet (not to be confused with an InfoSet in BW) query in a source R3/ECC environment, is created in tocde SQ01, and is a way of creating "quick-and-dirty" reports with summarized values, derived values, et. al. This can be used as the basis for a DataSource, if the queries are already built. If not, then a Function Module can perform and necessary aggregations, derivations or other transformational-type logic, instead of creating a query. I say this because I'd highly discourage using this as a source for a generic DataSource because InfoSet queries are usually extremely inefficient and can consume a lot of the valuable system resources.

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.
