Generic Extraction Problem

HI There,
I am trying to creat grneric extractor (with Table) on MBEW table .while i saving it is not saving.it is showing some some error .
*ERROR IS
Diagnosis
You tried to generate an extract structure with the template structure MBEW. This operation failed, because the template structure quantity fields or currency fields, for example, field LBKUM refer to a different table.
Procedure
Use the template structure to create a view or DDIC structure that does not contain the inadmissable fields.*
As per my understanding we can't creat table type generic extractor ..we can creat a view on that table then only we creat gerneric extractor with view.
Is my understanding correct..? or is there any onther assumption for the error.
Plz assist me.
Regards...KP

H there..
Thank you for the great responce...
As in the error...In MBEW table all the unit fields i,e currency unit fields( WAERS) are coming from T001 table and quantity unit fields (MEINS) are coming from MARA table.
i am thinking to creat a view with MBEW,MARA and T001 tables.i will seclect the char and key filelds from MBEW and related unit fields from MARA and T001.
i guess this would be the solution..plz respond.
Regards...KP

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 RAISE NO_MORE_DATA should be active (uncommented) in your code. Otherwise, the infinte loop occurs.

Problem in creating Generic Extraction

Hi,
I want to create a report for inventory analysis.
Standard datasources are not meeting the customer requirements.
Customer is also suggesting to go for generic extractions.
The below said view suffice our requirement.
view name : V_MMIM_WB.
In this view the fields : LBKUM is quantity field refering UNIT
SALK3 is currency field refering CUKY.
MBEW-LBKUM for this quantity field reference table is
MARA-MEINS.
MBEW-SALK3 for this currency field reference table is
T001-WAERS.
In my view i had given join conditions as T001-BUKRS = MSEG-BUKRS.
i had enhanced in my view MEINS and WAERS.
This UNIT and CUKY are coming from different Tables.
Then I tried to add the fields to the View and it went successful.The problem after this is the Data are duplicated
when i give this join conditions.
Pls suggest for any solutions.
Its sure for giving good rewards as the problem is more urgent...
regards,
Maqsood Ali

Dear Muhammad,
Basically you can use join for making that ..
But if you have made it, then the result still get duplicated..
I suggest you 2 ways:
1. Use this sintax: delete adjacent ..
(honestly i forget for the complete command, but you can see in the help).
2. You can Loop into the internal table, then you check ..
If the records is duplicated, then you need to delete it ..
Hopefully it can help you a lot..

Niel

For Generic:
>Go to Tcode : RSO2,
>There give the name of data source which you want to create like transaction data source or master data attribue or Text data source.
>enter
>again in the next screen you need to give application like SD or MM etc
>in the same screen need to select table/view or infosetquery or function module. these are different ways of creating data sources.
>Give the name for the same like if u r creating data source on table give the name of table.
>click on Generic delta which will there in application tool bar and fill the required columns in that screen like type of delta and all
>continue and save
>it will give all the fieds
>enable the check boxes based on your requirement like selection or hide or field only..

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)

Any docs regarding Table/View,Function Module for Generic Extraction

Hello All
I need to do Generic Extraction,for that if anyone has docs., I need docs on how to create table,view,Function module and infoset query ,on that pl forward to my id
[email protected]
Many Thanks

hi Amit
Thanks for your docs,but this docs i have already,do u have any thing different one,if so please forward?
Facing a Problem

what will be the problem?pl let me know how to create a view?
And also I need to know the diffference between database view,Manintenance view,Projection view and help view?
Pl let me know on this?
Many Thanks

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
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.
Need for customized generic extractor
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

Errors occurred during the extraction(Generic Extraction)

Hi All,
I am facing problems in solving BW Production issues .
The following are the Problem details.
Actually there are two Datasources connected to BW System One is from R/3 and other is from CRM.
The problem is with Delta Request which has been failed in ODS while uploading Data from R/3 in Background Scheduling but other DataSource is loading perfectly into BW System.
Its a generic extraction created based on View.
When i checked BW Side the error is displaying as follows:                                                                                Error occurred in the Data Selection.
     Error occurred in the Source System.
        No Data has been extracted from R/3 into BW.
But when i checked R/3 (Source system)
Firslty i executed RSA7 for checking Delta Records. The records are 0 for the Datasource.
I executed RSA3 with Full UpdateMode, the number of records extracted were displayed
when i checked with Delta Update Mode its giving the following error.
Errors occurred during the extraction
Message no. RJ 012
Diagnosis
There was an error during the extraction phase of the extractor. An exception 'error_passed_to_mess_handler' has been triggered.
Procedure
Check the function module and the call from the extractor check program
Messages from source system
see also Processing Steps Request
These messages are sent by IDoc from the source system. Both the extractor itself as well as the service API can send messages. When errors occur, several messages are usually sent together.
From the source system, there are several types of messages that can be differentiated by the so-called Info-IDoc-Status. The IDoc with status 2 plays a particular role here; it describes the number of records that have been extracted in a source system and sent to BW. The number of the records received in BW is checked against this information.

Hi,
If Idoc are already sent to BW then goto Monitor in BW and in Details tab note the Idoc no in OLTP, and goto R?3 and BD20 tcode and give the Idoc no and execute it.And see the records are came or not in BW.
Thanks

No BERDATUM while generic extraction with LDB ADA

We do a generic extraction to BW with LDB ADA. Therefore it was created an additional field in InfoSet on note ANLAV, where BERDATE=BERDATUM. BERDATUM is a selection parameter in LDB ADA. In extractor checker BERDATE is not filled.
Does anybody have an idea what the problem is?

Hi,
thanks for that hint. I checked this already. DataSource is ok and the field is not hidden.

Generic Extraction : Taking a lot of time

HI Experts
I have created ZKONV a generic extracter which is a copy of KONV table. It has around 16,00,000 records .When I´m pulling the data in to ODS it is taking a lot of time. it is taking around 5+ hours to load the data. Is there anything wrong with my Datasource why it is taking so much of time.
Kindly provide some inputs
Thanks
NLN

Hi Lakshminarayana
You got to check couple of things.
First goto the source system and see, how long the extract program is running. The long time may be due to poor source system performance or huge processing at the BW system side. If the job in the source system is running for a long time, then check the source system resource. Build proper index on the mentioned table and see whether it has improved the performance. You can ask the basis people for the SQL trace and they let u know what kindof indexes u can build on the tables.
If the processing is taking more time, then u have to imrpove the start/update routine in the BW side. Please let us know, where exactly u have the problem. Then we can think of resolving it.

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.

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.
