Generic extractor Delta problem

hello,
i have created a Generic extractor based on the AUFM table and the delta field is MBLNR (Material document no) that is a numeric pointer used for delta. My problem is that when i pull the delta not all records are being pulled. Why is that so? Can anyone give suggestions.
thanks
Laura.

Well, using Function module is one approach. I can provide you another approach.
You can create a View based on the following tables
AUFM and MKPF,
use the join condition
AUFM-MANDT= MKPF-MANDT.
AUFM-MBLNR = MKPF-MBLNR
AUFM-MJAHR = MKPF-MJAHR
In AUFM select all the fields that you want and MKPF select the "Accounting Document entry date" field which you can take it as delta field and select calday as your delta option.
Once view is created, you can generate the datasource.
Please check this option.
I think it should work...
Thanks

Generic extractor question/problem

Hello,
I want to create a generic extractor on custom table which should delta enabled . This custom table has ERDAT( creation date) and ERZET u2013 Entry time but the client is asking me to use both fields for delta functionality . I am not sure how to do this . Please help .
Regards,

As you said client want you to use both the date n time stamp field to extract delta you can follow the below steps.
- Create the generic data source as per you requirement in order to pic the delta
- Open you extract structre and append the field TZNTSTMP, this is the field which holds the time stamp.
- to setup deltas click on generic delta --> select time stamp(UTC)

BW GENERIC EXTRACTION DELTA PROBLEM

I have a problem for extracting delta from R/3 to BW.
Init data is loaded from R/3 to BW system for ZST_ORDER datasource.
Repair full request and selection parameter is created on date August 1st 2007 to August15th 2007.
During the delta extraction - A lot of records around 500,000 records are getting extracting from R/3 to BW.
R/3 side - There is only 5 entries available in AUFK table.
It should extract delta only less than 35 entries.
ZST_ORDER is generic datasource . Delta captured field is DATUM -New status changed record value 2.
Advance Thx for your help. The code looks like
FUNCTION ZST_ORDER.

hi,
for that quantity SALK3 is referring a different table in the reference field for your table fields. check that field and refer the correct table for that field in table view.
table join has a problem in that. i think your joined some other table with that field. replace the field assignment or create a new view.
hope this help you

How to reduce long extraction time - Generic extractor based on view

Hello. The previous thread about this error was closed without any answer.
I'm in the same configuration.
"Using a generic extractor (Delta enabled on confirmation date) based on view to load data from ECC6 to BI.

Parth Kulkarni,
following the note and the other thread, I've check the index 4 of the table COEP.
Here is what I got:
Index ID           COEP             - 4
Short text         MANDT/TIMESTMP/OBJNR, Index for Delta read method (CO-PA)
Last changed       SAP             04.01.2010
Status             Active          Saved
                   Does not exist in the database
DB index nme
    Not defined as DB index in the ABAP Dictionary
Is the fact that it doesn't exist in the database a problem ?
Is the fact that it is active is good enough ?
By the way thanks for your speedy reply !

Delta loading through Generic extractor - function module not found

Hi,
I'm working on a BW3.5 system and we have some generic delta FM extractors. One of these is called ZBW_CONF_DELTA and the FM is also called ZBW_CONF_DELTA. It is a delta-enabled extractor. Whenever an extraction is done in the init delta mode, the data gets picked up from SAP.
However, whenever we load subsequent deltas, the extractor brings zero records. When I look in the SM37 logs in R/3, it says "Function module /BIC/QIZBW_CONF_DELTA0001 does not exist"
I'm not sure where the "/BIC/QIZBW_CONF_DELTA0001" function module name came from, because I haven't given it like that (if I did, the init load would also have failed).
Due to this problem, I'm unable to perform any delta loads. Is there anything I could be doing to fix this?
Regards

Hi,
First check how extractor works in R/3 side using RSA3
Make a full load.
Now check the generic delta field of your generic extractor, lets say changed on date.
Do the SAP transaction ( take help from some Functional COnsultant ) to update that delta field. Note that record.
Now if u do the delta load with same extractor, you are suppose to get that record.
If not then there is some problem with FM or extracor.
Let me know what happens.
Thank-You.

Vinod

Dear Yogesh,
Try to debug the code by putting a break point at select statement...is the FM Syntactically correct ??
Check the Select statements..if all fields are not required avoid using Select * , and use always for all entries rather than JOINS..
Note : For Joins you have to specify the Fields in the Select...Dont use Select * ....
Hope it helps..
Thanks,

How to use 2 date field as delta control in generic extractor.

Hi colleagues:
I have developed a generic extractor to extract logistic data: Purchase Orders and Invoice. In order to do that, I have defined a view joining EKBE, EKKO, EKPO, EKET tables on R/3. By this approach, the delta mechanism is supposed to be controlled by the EKBE-BUDAT field and also by the EKPO-AEDAT field. Both fields are available on the view used to create the Datasource. However, the Datasource creation allows us to define just one field as delta control.
I have a few questions regarding to this scenario:
1 - Is it possible to define 2 fields as delta control field on Generic Datasource?
2 - How about creating two similar Datasouces, one having AEDAT as delta control, the other having BUDAT as delta control, and then connect those Datasources to an unique Infosource on the bw side?
Best regards
Waldemar

hi,
1 - as far as I know it is not possible to define 2 fields
2 - this workaround is used often in cases like yours.
Just remember about order of extracting: first you extract new documents then changed

Andrzej

Deltas in generic extractor

I am trying to have more then one field in my generic extractor as a delta and so far i can only set one field as delta in my generic extractor....can someone help me in setting more than one field as a delta in my custom generic extractor ????

The last delta performed will be stored in the ROOSGENDLM table....
Use this value and then fetch the delta pointers you need..
Here is how I would do it...
In the FM :
Look up value of DELTAID from table ROOSGENDLM for your datasource - this will give details of the last delta performed..
Then use this value and search for the actual delta pointers in your custom table - then perform your delta logic within the FM...
P.S The entry in ROOSGENDLM will come only after you init the datasource...

Delta in generic extractor.

Hi Everyone,
I have created one of the generic extractor on a table and the other one on a view. While selecting the GENERIC DELTA, I let the numeric pointer selection checked.
Now, my question is will it allow me to do delta load in my cube using this extractor?
2nd question is how?
3rd question is if not then what is the change that I need to make so that it allows me to load the delta load. How this changes need to be made can you please explain step by step. thanks in advance.
My issue arose after loading the data when I went to change the InfoPackage to load the delta part, I realised in my InfoPackage I do not have the choice to load delta. How do I settle this. Actually this is an inventory cube where the data is loaded at the end of each month and now when I wanted to test it for today's month I realised that I do not have the choice to load delta for inventory load.
Please explain. Thank you once again in advance.

1. my question is will it allow me to do delta load in my cube using this extractor?
Yes... you build Generic Extractor with Delta based on Numeric Pointer. Material Documents is the Perfect Example for that (We can't Sales Document or Purchase Document for this).
2. 2nd question is how?
Simple enable Material Document Number Fileds for Numeric Pointer (Select Numeric Pointer... provide Mat. Document No. field i.e. MBLNR).
3rd question is if not then what is the change that I need to make so that it allows me to load the delta load. How this changes need to be made can you please explain step by step. thanks in advance.
you need to create Material Documents in SAP R/3. If you build your Extractor on MSEG Table. You need to create any Material Document which populates in MSEG.
I don't remember wht exactly option we will get in Infopackage for Numeric Pointer. To my knowledge, it should give Delta only in Update Tab page.
Hope this helps.

Error in delta generic extractor

I made a generic extractor using a Module Function. And I used the RSVD_BW_GET_DELTA_DATA function, as an example to implement the Delta process for my own generic extractor.
Although when I executed the Delta process in the RSA3 transaction, the program did not use the function I made, but used the RSC1_DELTA_BIW_GET function! So the delta process did not extract any data.
I also modified EXMETHOD field from the ROOSOURCE table:
I changed the status from F2 to F1.
Could you explain me how the delta process works in a Generic Extractor?
Is any special configuration that I missed?
Thanks for your cooperation and regards.

Hi Sirneni,
Is your Init load in BW successfull. Only after
successfull completion of init load in BW the data source appears in delta queue RSA7 in R/3. Also check whether any materials are being changed in R/3 because u r delta is based on last changed date.

How to do Delta upload using Generic Extractor built on Function Module?

Hello Guys,
I have never created a Generic Extractor using a Function Module. I wanted to know how can we support Delta mechanism if we create Generic extractor using Function Module.
Regards,
Abhishek

Hi Abishek,
Please check the standard Function Module RSAX_BIW_GET_DATA for your delta mechnism.
Hope it will help you.
Thanks,

Generic Extractor using FM with Delta Logic

Hi,
i want to create a generic extractor with Delta Logic based on a FM.
The extractor works fine for full loads (extractor method "F" or "C"), but delivers no record for the extractor method "D" (Delta). I placed a hard coded break-point in the FM, so that the processing should stop while testing it with TC "rsa3". Using the extractor method "D" the debugger doesn't stop. So it seems, that this FM will not be processed for method "D". What could be wrong?
I tried different ways to create the generic extractor:
First i copied the template "RSAX_BIW_GET_DATA_SIMPLE" and tried to get the information for delta-run by "LOOP AT i_t_select INTO l_s_select WHERE fieldnm = 'DATE_FIELD'." But as the processing for method "D" does not consider the FM, there is no chance to get delta data.
On second try i used the template "RSAX_BIW_GET_DATA" and changed "EXMETHOD" from "F1" to "F2" in table ROOSOURCE for the Data Source. In this case i get information about the Update mode (Parameter i_updmode). But the processing leaves the FM for extractor method "D" out too.
Does anybody know, why the FM is not processed for extractor method "D"?
Is there another way to get delta capable extractors based on FMs?
Thanks for help in advance!

Hello

Delta update for generic extractor ?? Urgent!!!!

Hi All
In my project I am pulling data from 4 R/3 tables... I have created view & then Generic DataSource.
Can a delta update be set-up for the generic extractor based on adds/changes to the R/3 tables?
Thanks & Regards,
Sheetal

Generic extractor is not reading delta

Hi !
I have a generic extractor with delta queue, for a Z view.
The delta is on 'ZLOAD_DATE' field / calendar day /safety interval upper limit = 1 / new status for changed records
In BI the init with data is ok.
In ECC the delta queue (RSA7) show as actual status: 03 June 2010
then, I add 3 new records
ZMAT    ZLOAD_DATE
x            01 June 2010
x            02 June 2010
x            03 June 2010
But when I run again the delta load in BI, dont load any records.. (0 records readed)
> What is wrong?
Thanks in advance!

Hi Prem
The new record were created after the init (the same day), but specify manually in the ZLOAD_DATE several dates (diferent from the real load date, today)
1 - If I load records today and after run a delta, can I see they in BI or I need wait until tomorrow?
2 - if the upper limit is regarding the actual date, which is the meaning of specify a delta key field?
3 - if I want a delta with the same behaivour than standard delta, do I need add the field timestamp to the table, and change the extractor?
Thanks for your support!
