Generic data extraction

Hi guru's.
I like to know how many fields can be taken from table for the view in GE , Is there any limit? we need to set delta for each field for delta extraction?.
Regards.
Harry

Hi Harry,
I am not aware of a limitation for the number of view fields, but in case of a generic delta you only have the choice for one field (a timestamp, a date or a numeric pointer).

Delta in Generic data extraction

Hi all,
I have a doubt here,
What is the delta in Generic Data extraction?
What are the types?
and what are their significances?
Please give reply.
Thanks
Surya.

Hi Surya,
If a field (date, progressive document number, timestamp) exists in the extract structure of a DataSource that contains values which increase monotonously over time, you can define delta capability for this DataSource. If such a delta-relevant field exists in the extract structure, such as a timestamp, the system determines the data volume transferred in the delta method by comparing the maximum value transferred with the last load with the amount of data that has since entered the system. Only the data that has newly arrived is transferred.
To get the delta, generic delta management translates the update mode into a selection criterion. The selection of the request is enhanced with an interval for the delta-relevant field. The lower limit of the interval is known from the previous extraction. The upper limit is taken from the current value, such as the timestamp or the time of extraction. You can use security intervals to ensure that all data is taken into consideration in the extractions (The purpose of a security interval is to make the system take into consideration records that appear during the extraction process but which remain unextracted -since they have yet to be saved- during the next extraction; you have the option of adding a security interval to the upper limit/lower limit of the interval).
After the data request was transferred to the extractor, and the data was extracted, the extractor then informs generic delta management that the pointer can be set to the upper limit of the previously returned interval.
Hope now is clearer...

Error while activation Function module for generic data extraction

Hi,
I have created a generic data source ZMATERIAL in which i have selected the Extraction by Function module. I copied the function module RSAX_BIW_GET_DATA_SIMPL to ZMATERIAL_FM, but when i activate this module it gives me error

Urgent........Generic data extraction........

Hi Experts,
I created a Generic extractor using a function module
1.I created a Function Mudule and tested the same in debugging mode it seams it is fetching the data properly.
2. I created the extract structure using SE11 in my extract structure I have around 15 fields of type CURR. so I specify the reference table and reference field for all the above 15 fileds.
3. I try to ctreate a Generic data source using RSO2 using a field AEDAT .
I got 15 error messages that the
" the unit field CURR of the field PKAZ1 of the data source ZBWNXXXXX is not visible or stopped out or hide or..........ausgeblendet."
How shall I handle this issue........
Thanks in advance.
Cheers
Sailekha

Hi
I am not tested in RSA3. I just tested whether data is fetching properly or not by Debugging the Function Moudule.
to be frank I am new to this concept. How shall I populate currency and unit fields for Keyfigures in FM.
In my case the data for these KF's is comming from a table
to get the data from the table
I use the following code
Wertarten puffern *********KF Buffering
TODO: Eventuell zu Performanceverbesserung die zu
 selektierenden Wertarten weiter einschränken
 select POS_SEQ_GUID
 VAL_TYP
 CURR
 VALUE
 PERC
 from /bwn/npos_vl
 into table ct_pos_vl
 for all entries in ut_polpos where
 POS_SEQ_GUID = ut_polpos-POS_SEQ_GUID.
Fetching the KF data
FORM wertarten_fuellen USING US_POLPOS type s_polpos
 UT_POS_VL type t_pos_vl
 CHANGING CS_DATA type Z_S_POLPOS.
data: ls_pos_vl type s_pos_vl.
loop at ut_pos_vl into ls_pos_vl
 where POS_SEQ_GUID = us_polpos-POS_SEQ_GUID.
case ls_pos_vl-val_typ.
 when '001'.
 Originalversicherungssumme - VAL_TYP = 1
 cs_data-ZIOVB = ls_pos_vl-value.
 cs_data-ZIOVB_C = ls_pos_vl-curr.
 when '002'.
 Signed Line in Summe - VAL_TYP = 2
 cs_data-ZIZVS = ls_pos_vl-value.
 cs_data-ZIZVS_C = ls_pos_vl-curr.
 endcase.
 endloop.
endform.
I used the above code to buffer the KF data and and to fill the KF data . is it the correct apporach to populate the KF's in FM
can you please send me sample code to to do this.
any suggestions please............
Thanks in advance

Generic Data Extraction : Setting of Upper and Lower Limits

Hi all,
I'm doing the delta extraction for this non-standard infocube which stores data about measuring documents. The strategy I used was to first update a ODS with the new/changed measuring documents determined by their last changed date. Then it will update the infocube with the new values. In order to get the delta measuring documents to go into the ODS, I specify a upper limit of 1 and lower limit of 0 in the extractor's generic delta settings to get measuring documents that are created/changed the previous day. But the system will still take in the full set of measuring document.
Is there something that I have missed out?
Thanks

Hi,
I dont see anything wrong with what you have done. That is correct, it is recommended that the upper safety interval should be set to 1.
But according to you, the system still gets the newly changed records as of current day. Have you checked the update mode? It should be DELTA UPDATE. It might be marked as FULL UPDATE.
Have you successfully initialized the DELTA Update?
Are you using an appropriate DELTA field? It should be a Calendar Day.
Hope I did help and if i did, please grant points...

Generic data extraction and loading to cube

Hello guys, I am trying to load R3 data thru Gernic extraction to infocube in bw3.5.
I just created generic DS and activated it and also Replicated in BW side.
I am trying to extract transaction data - from FI , DS has Ship Info Table fields in the extraction structure.
Everything got activated and now i am in BW side, just assigned DS to infosource.
But i am stuck in Transfer rules, all infoobjects on the left are empty and it wont let me activate.
I am really confused, Should i be creating infoobjects first , because i havent created infocube yet.
My DS has about 12 fields , I really need someone to tell me why its not activating Transfer rules, Comm structure is still empty.
Should i be creating INfocube first with KF and Chars?or how am i supposed to map these DS fields in the Infocube (my data target)?
I guess i am not clear at this point, even with LO extraction I could get create DS and replicate in BW , but once i am in BW i become clueless i should say.I did search other posts here but couldnt find anything that help me understand this.if someone could explain me in a simple terms i would appreciate it.
I have created DS with extraction structure, i am in BW , so whatever field i selected in extract structure in R3 side f rom the table , is that going to be Chars and Key figures in my Infocube once i complete Loading ? or how would that work? Why would we need to chose specific Table when creating view , assuming that we already know the data that we need for reporting purposes, we would know those data should be on what table correct?
please drop some lines to help me thanks

hello again, i am writing this since i didnt get any response. I would really appreciate it if someone could give me little hint , i have been practicing on my own using bw system and need help from you Pros.
My previous question was regarding Transfer rule . I am still not able to get through that steps.
This is what i have done so far:
-created DS generic for transaction data, using View VBAK table (not sure if this was the right table, i just wanted to see if i would be successful loading data in the cube).
- ACtivated DS, replicated in BW, Assigned INfosource.
- I selected 15 Fields from DS (extraction structure ) from that VBAK table.
- But when i am in Transfer rule ./structure screen, there are many fields appearing.
- It will let me active the Transfer Rules, however i also created InfoCube , it asked me to chose at least one Time Chars, and KF. But i used Template using my infosource, there were no KFs . so i figured i need to change Transfer rule. I tried to create Key figure infoobject on the right side of the screen in Transfer rules, but it will not move to the right when i tried to transfer it.
My question is, why there are more fields in this screen and some fields are not appearing the one i selected.
Since i chose transaction Generic DS,is that why i have to have Key figures? did i chose worng table VBAK for practice purpose? i dont really see much Keyfigures when i looked the content of this table using SE16.
Guys please suggest me , what route should i take to get through this confusion.
My main objective here is to simply load R3 data using Genric DS(transacitonal) into a customized infocube.
I get error when creating Update rule, infosource and infocube wouldn not link, i think its becoz i didnt have any keyfigures available when creating Infocube ? how would i chose one?
anyone please throw me some suggestions ..i would really appreciate it.thanks again for reading

Generic data extraction from R/3 into BI

Hi Friends,
We need to extract some data available in the R/3 side to BI. I have written code in a function module which brings the output into the table e_t_data. now by attaching this function module, we created a Data source also. and then from BI side we replicated this Datasource. when tried to extract the data at BI from R/3, the process keeps on running with out bringing any data into BI.
Regarding this, i referred some docs in the forums. They say that we have to go with the approach followed in the FM 'RSAX_BIW_GET_DATA_SIMPLE'. I have done all the coding and settings similar to this function module. there is no syntax error and code produces the required output in e_t_data.In that FM they used some Select statement under the Open Cursor statement. But in our requirement, we are not selecting anything from Table. but we generate some data by some calculations and these data will be our output. If it is the case, can't we use that open cursor approach...? we need to get the output data not by any select statement but the output will be some internal table entries which are created by some calculations.
Please suggest how to handle this.
Thanks in advance...
Regards
Ram

Hi,
just fill the output table in your FM by yourself - it will work.
I guess at the beginninig you are selecting data from one (or more tables) and than calculate the final output later. You may use the cursor for packing the data into suitable packages. However, an exact package size is - in most cases - not possible with that scenario.
Kind regards,
HP.

Generic Data vs Generic Delta

Hello,
When do we use Generic Data Extraction?
When do we use Generic Delta Extraction?
Thanks

Roshan,
When you create a Generic DataSource you have the option to make it support delta functionality using your specified charactetistics which will be used to track deltas for example document date etc....
We create a Generic DataSource if the existing BC does not provide a standard datasource for the same.
Whether you want it to be delta enabled or not it depends on your scenario.
Hope this helps.....

Error while doing DELTA Extraction (generic data source)

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

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

Error while testing Generic Data Source extraction

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

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

Extraction, Flat File, Generic Data Source, Delta Initialization

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

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

Satya

Generic Data Source delta is not extracted

Hi,
There is a problem in extracting the delta records using Generic Data Source. Delta records ( New / Modified records ) are not posted in the RSA7.
I'll Explain you the Scenario I have done. Created a generic data source in R/3 using view. In the view there is a field Sales Order No. I have enabled the delta update for this field. In the generic delta i have chosen delta type as Numeric pointer.
Extracted the entire record using full update and after initializing the Delta, it extracts the delta record well ie. it only extracts the sequence of Sale Order No. First I extracted nine records(i.e 10001 to 10009) using full update. again I entered a record in underlying table with sale order no as 10011-10013. It extracts those records into BW system. Then again I made an entry in the table with sales order no 10010. But the record is not extracted. Even though I tried of specifying safety lower limit as -3. Still it not extracting the record(10010).
And what if I posted a value of sale order 10014 with the same. what should I do?? Help on this plz.
--Durai.S

Hi SVS,
Thanks for your reply.
I followed this in my scenario. But I don't understand why it is not extracting? even I specified the safety limit of upper and lower values in the generic delta.
Here the below explanation shows that the delta record can be extracted even if the pointer value is greater than the posted value.
Numeric pointer (last extracted value 10011; Data in underlying table (Max value = 10025) )
Data would be extracted from a min-value of 10010 (lower limit adjusts the last counter 10011 by specified value u2013 1)
max-value of 10020 (after adjustment for upper safety limit u2013 by 5). The current pointer would now indicate 10020 in
RSA7.

Code Page Setting while extracting data using Generic Data Source

Hi,
Can anybody tell me about the Code Page setting used in Generic Data Source in SAP BW 3.5?
I am extracting data from a Master Table using Generic data Source, but the data which is in Ukrane language is getting loaded as "#". Where do we set the Code Page for it?
Regards,
YK.

To continue with earlier question, is there any particular setting for a master data, to load non english data as a text of master data?
I want to load TEXT of a master in Ukraine language. I am extracting this text from the P table of same master (From Description Field). But TEXT is not getting populated whenever it is Ukraine language. English TEXT is populated correctly.
Please share your experiences...
Thanks,
YK.
