Hi,
please search the forums. This question has been asked already a lot of times. Additionally you might check my business card --> there is a link to a weblog related to that issue.

Enabling FI-SL extractor with delta capability
I am working on enabling FI-SL (3FI_SL_*) extractor with delta capability.
Implemented OSS note 328197 successfully and also related OSS notes.
This works on totals table. Source system is 4.6C
Tested BW01, BW03 and everything seems to be fine, and shows as if extractor is enabled for delta loads.
I have done initialization. it works fine and got records.
But when I do delta - it shows ZERO records.
In RSA7 also I see Zero records.
If you have any experience , will you please share with me.
It's a very urgent one.
VenuCreate some records in the source system so that the base tables for this extractor will add some records.
Then check rsa7 whether it shows any records for next delta.
As Hari said..there might not be fresh records created or records changed,if you do delta load immediately after an init load.
cheers,

Generic Extractors with Fm / Finding out tables used
Hello Gurus,
for a requirement, i would like to find out the table used in a generic extractor with function module.
I can see the structure with the objects used but not the tables where they are from.
How can i find that out?
Thank you
PatHi Gilo ,
The best way to find out the tables used in the function module will be to analyze the code . Check all your Select Statements in the code and see the tables being used there .
Sometimes in the code , we use standard function modules from the ECC. Check those standard FMs also and see what table they are using .
Hope the above reply was helpful.
Thanks & Regards,

Generice extracttion with delta
if we do generic extraction with delta in which table luws will be stored
LUW's for generic delta can be monitored in RSA7.
BW Delta queue is based on queue functions in the RFC technology for SAP Web Application servers (qRFC). The data is stored in the following 3 tables:
1. TRFCQOUT (Client Dependent pointer table per queue name and destination.
2. ARFCSSTATE: Likn between TRFCQOUT and ARFCSDARA
3. ARFCSDATA: Compressed data for tRFC/qRFC
refer following: http://help.sap.com/saphelp_nw04/helpdata/en/6f/66bca6ae43744283d74f1e456ff6c0/content.htm for delta queue maintenance. -

Generic FM extractor with Delta
Hello all,
I am trying to create a delta function module extractor on a table. I have creation date ANDAT, last change date AEDAT and a deletion flag on the table.
FM has to handle history, new and changes.
How can I generate delta? Can I just use RSO2 to set up delta? How can it be done? Also, can I get the code for a generic FM delta extractor?
Please help.
Thanks,
Anirudh.Hi Sajeed,
So, I do not have to handle delta in the extractor at all? Just create a function module based extractor with all the fields and actually take care of delta in the infopackage??
The creation date is for newly created records and the change date is for changed records.
My email is [email protected]
Thanks,
Anirudh. -
Function Module Extractor with Delta Functionality
Hi Friends,
I have to extract the entire data of CDPOS table in R/3 , as its a cluster table I am unable to build a view, I am planning to go for FM extraction, Could someone help me as how to build it with Delta Functionality.
I think I need to develop the Datasource, with Extract Structure,( Do I need to create a Structure in SE11) Please help me out .
Thanks,
KrishHi,
you can either use an existing structure or else create one on your own. (SE11).
The DeltaHandlig fairly easy.
When having finished the extractor (FunctionModule, Structur and DatasSource), go to the "generic Delta" button and select the relevant field.
The Generic Delta and its DeltaPointer is managed within the DeltaQueue (RSA7) and works more or less like a selection. Don't think too hard about it in your function module except taht you need to select by this field in your FM.
Did that come clear?

Enhance LIS_ extractor with delta load
Hi all,
I need to enhance 2LIS_02_ITM or 2LIS_02_SCL with account assignment (EKKN). How should I handle the delta from account assignment? It is in 460 environment. I'd like to have similar extractor as 2LIS_02_ACC which exists in 700.
How should I approach? Which way is better?
Options one: Create a generic extractor, delta base on AEDAT in EKKN table. Create custom ODS....
Option two: enhance current 2LIS02_ITM or 2LIS_02_SCL, add cufs. But how to handle the delta?
Thanks
J.Hi J CHEN
In my opinion first check with MM -Purchasing consultant whether the delta in account assignment is linked to purchasing document changes or not ? (check whether delta is supported or not ...you can do this testing in SAP R/3 Side) and if answer is YES then you should go for Option 2 which is relatively simpler.
hope this helps

Function Module Extractor with Delta
I'm very new to working with the BW, so I hope I'm explaining my question in a way that makes sense.
I need to make a BW extractor that pulls data from at least one table, possibly more, and which also calculates some data.
I think the only way I can do that is by using an extractor with a function module.
I've been looking at the examples in function group RSAX, and I think I sort of get it, except for one part.
I'm really confused about how the delta works.
I'm looking at the example: RSAX_BIW_GET_DATA_SIMPLE
Does it even use a delta?
I'm trying to understand how the delta gets passed, and how it gets used to filter the data in the function module. I'm not sure if it's something I need to code in myself, or if it's something that BW does by itself, or what.
I'm not sure if I'm making sense, but if anyone could help me, I'd appreciate it.Thanks guys, you've been super helpful so far, so I'm just going to keep asking questions. I promise to award points at the end
I'm looking at it now, and I think if I change it to read from a table, instead of read from a function module I can use the 'numeric pointer' option for the delta. (Does that just mean a number? For example, payroll runid is a number, so I could use that and only get new payroll runs?)
However, there still are some calculated fields they want. Someone mentioned doing that on the BW side. How would that work?
Sorry for such vague questions, but any help is really appreciated. -
Generic Extractors with different ways
Hi guys,
When we are creating Generic Extractors, we have 4 options:
1. Using Table/Views
2. InfoSet Query
3. Function Module
4. Value Domain Field ( Only for Text Extractor)
I would like to know, when we will use these options particular cases with real time examples?
Awaiting for your valuable help.
Best Regards,
Kishanwe can greate generic datasources for customer defined tables as well as when we need to extract data from the existing r/3 tables.
when the client wants his own table to be build and he wants to extract data from that table go for generic.
when we need to extract data from r/3 table ex. purchase requistions are stored in eban table if you want that data in bw create a generic datasource based on table and extract data.
If you want to extract data from two or more r/3 tables then go for view.
infoset is a semantic view of data source and it is not a physical data target. infoset is a view but allows outer joins between tables. in that scenario go for infoset.
when some function modules are retrieving data in r/3 then u can use those function modules to retreive data in BW. -
Generic Extractor with ALE-Delta Capability

Please let me know your views regarding same.
And i promise to return and reward the answers.
Thanks&Regards,
Augustine.Hi Augustine and welcome to the sdn,
it is not possible to get a delta on the fields you added to your view. You have 2 options.
1st: add fields aedat and erdat of table mara to your view. Create 2 infopackages in BW to load all records created and all records changed in a specific time range.
2nd: create a fm and select the required fields from mara and makt that are created or changed in a specific time range. Create a ddic structure as extract structure containing spart, matnr, spras, maktx and a date field for the generic delta. See also this information about fm-extraction: /people/siegfried.szameitat/blog/2005/09/29/generic-extraction-via-function-module

Regards,
PraHi Suneel,
You can load delta to write optimized DSO. Your Data source will have delta load (through infopackage) and then with DTP (with Extraction Mehtod --> Delta) you can load delta records to this write optimized DSO. So only the new requests, which are not loaded yet will be loaded to WO-DSO. I tried it in system and it works.
They can be used in the following scenarios:
● You use a write-optimized DataStore object as a temporary storage area for large sets of data if you are executing complex transformations for this data before it is written to the DataStore object. The data can then be updated to further (smaller) InfoProviders. You only have to create the complex transformations once for all data.
● You use write-optimized DataStore objects as the EDW layer for saving data. Business rules are only applied when the data is updated to additional InfoProviders.
it is used when you don't want to wait for DSO activation and error troubleshooting. It will make raportable data available instantly.
Hope it helps...

Ashish

Generic datasource with Delta queue
Hi All,
I 've created a generic datasource on prices tables A* and KONP. Next, I used HowTo document "create generic datasource that uses delta queue", finding the right BTE that could catch prices modification. Up to this point, everything works fine.
I've extracted an Init delta to BW and now, on R/3, in RSA7, I can see a delta queue for my generic datasource.
When I modify price conditions in VK12, BTE works fine and I can see the counter in RSA7 increasing. I also can see new entries in table TRFCQOUT with status READY. (either in SE16 or in SMQ1 )
The problem is :
- in RSA7, if I want to display the posted data, system returns an empty list (whereas the counter is different from 0)
- when I run a delta InfoPackage, no data is sent to BW, but in table TRFCQOUT, status has been changed to READ for entries that previously had status READY (and old entries that had status READ due to a previous delta upload are deleted)
Does anyone has any idea about the reason of the issue ?
Thanks for any help
AJSure, I can.
The problem was in the specific coding that update the delta queue : not all the fields were updated and some of these fields were used as selection criteria in th delta infopackage...
in RSA7, when you try to see the data in the queue, the system only shows you the records that match the selection criterias of your delta IP...so in our case, because of those empty fields, no records were selected...

i would like to know how i can copy a gneric datasource with function module from one system to the target system.
Thank you
CheersHi Anesh,
thank you for replying.
Since the Datasource will have a new new in the new system, i will create a new one.
Create a generic datasource base on the table is not the problem.
My problem is how could i copy the FM in the new system?
If you can help me on that, it will be fine.
