Generic Extractor with ALE-Delta Capability

Hi all,
I need to create a generic Data source based on 2 tables with fields: MARA-SPART.
MAKT-MATNR,SPRAS,MAKTX.
so i created a view on same and used it in creation of data source in T.C: RSO2.
My requirement is to make this Data source
Delta-capable using ALE-Delta mechanisum.
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.

Hope this helps

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
Pat

Hi 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,

Generic Datasource with Additive Delta

Hi all
I have a question.
In whic case can I use a generic datasource with additive delta?
Does this delta mode make sens only with function module extraction?
If I extract data directly from a table, can I use this delta mode only if a field represents changes?
Thanks for your help!
S.

Stefania,
    To my knowledge what you are thinking is wrong.
we have 2 Methods for Generic DS.
1. New status for changed Records.
2. Additive delta.
New status for changed records means
New Order
order no    quantity
1000          10
order changed to quntity 8. then 2 records will posted 2 BW in first case.
1000          -10
1000            8
if you come to Additve delta.
for the same case it will send the same record as
1000          10
changed records
1000          -2
this is the difference. New status with changed records should be used only in association with ODS not cube becoz we don't have overwrite option.
Additive delta we can use for ODS and Cubes with update mode Addition.
Hope this is clear.

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,
Kishan

we 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.

How to copy a generic extractor with function module into a new system?

Dear Gurus,
i would like to know how i can copy a gneric datasource with function module from one system to the target system.
Thank you
Cheers

Hi 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.
Thanks

ALE delta extract for HR master data

We want to create some R/3 delta extracts based on the HR PA* tables using the ALE delta extract function of generic extractor. Has anyone done this before? Are there any OSS notes or documents that I should look at? Thanks!

Hi Bill Faison,
This is very old message. I think your problem must be solved. If it is not then: yes we can extract Data from R/3 with ALE Delta .
You have to perform below steps.
1.     In your Table you need to activate ALE change   pointer.
2.     Create change documents for required table.
3.     Created Generic Extractor with ALE Delta.
Hope this will help.
Let me know if you have any concern or issue in this regards

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!

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.

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!

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...

Generic Extractor on Table VBAP

Hi Gurus,
I want to develop a Generic Extractor on table VBAP, but unfortunately its not giving me the extract structure when I save in RSO2, the screen wherein we select our fields are not displayed. Is there anything i am missing in the steps. Pls help us out with this issue.
I am able to create the generic extractor with other tables with usual proceedure.
Thanks in Advance.
Regards,
MSS

Hi
This is the problem with the amount and currency reference fields in your extract structure.
"This operation failed, because the template structure quantity fields or currency fields, for example, field CMPRE_FLT refer to a different table."
As you have an amount field, the currency reference table might be different and hence, it is giving this error.
I think u need to create view and then append the currency or quanity fields , and populate them through User exit.
Hope this helps.

Generic extractor and an append structure

Hi all,
this system is driving me crazy. So, that's something worked in former times..
I created an generic extractor on VEKP. I have not restricted to any selection criteria or hide any field. The system generated the extractor and everything is fine. THEN I created an append on the generic extractor and put different fields inside the append. I want (and this works) to fill this different field via user exit for extraction. All field in the append are having the prefix ZZ, all field are characteristic and there is no inconsistency in the append. I activated the append.
AND NOW - none of the fields of the append is available in RSA6 to hide or none hide or do anything. They are not available. By checking with SE11 on the generated structure - all field including the append are there.
We are on ECC 5.0 with PI 2004.1 for 5.0 SP 10.
Can anyone help. As i told you, this worked in former times (with SAP 4.6C with PI 2004.1 or lower).
Regards
OJ

Hi Siggi,
I have not created an special Append on the VEKP. I created an generic extractor on the VEKP. All fields of VEKP are available and I can hide or choose selection-field for all of these fields. No problem.
i created an append on the extract structure via RSA6 - enhancement. I know that after generating the generic extractor with RSO2 all settings done in former times in RSA6 are lost. But, my problem is: I can not see any of the fields I put into the append. They are not there. Not in ROOSFIELD and following not in RSA6. And that's the problem.
Thanks for your support.

0WBS element (external format) as append field in generic extractor?

Hi Guru's,
we use an generic extractor for our CO-PA data, as a join of different tables. Now I get the issue with this internal format of PSP element. It is of NUMC 8 and my basic data PSP element is CHAR 24. As they are not matching I want to add the POSID as an append field. But how to do this?
In table PRPS I found the Include PRPS_INC an thought about using this in my extract structure? Is this possible? How do I need to go on and to simply have my additional field - with content! - in my extract structure?
First I used an append and put in my include. As there are no fields extracted to BI I think this is wrong!? How can I delete my append?
Thanks

Generic delta extractor on view with ALE

Hello.
Extractor 0RT_WRF1_ATTR has type V and generic delta setting Numeric Pointer. Generic delta field is empty. Delta Process = A (ALE Update Pointer (Master Data)). ALE delta setting includes all fields of extractor structure. But changing one of these fields doesn't push new records into datasource.
Can you please explain, how generic delta works with ALE pointers аnd why no data is delivered?

CC,
Check on deletion data available in table(with any indicator updated) or not available in table.
If not available, you can not get delta through generic datasouce.
Hope it Helps
