Why to use setup tables in LO extraction

Hi gurus
please send me answer

Hi,
Think of the SAP application tables as Production system. Now why dont we directly do reporting on these tables or why cant we use these tables instead of ODS as these already have detailed data.
One of the major reasons is performance. If you want to load this data to BW directly with out setup tables, you cannot be sure that you have correct data in the BW system as these tables are changed by the transactions. If you still do not want to use setup tables, you should stop any changes to the tables, which is impossible (will impact the business).
I believe this is why SAP does not allow direct access to application tables and has brought in the concept of setup tables. The setup tables hold the data for us to transfer and any changes in the data records is moved to the delta queue.
Please correct me if I am wrong.
Hope this helps!
Regards,
Maddy

Hi revathi,
The R/3 database structure for accounting is much more easier than the Logistical structure.
Once you post in a ledger that is done. You can correct, but that give just another posting.
BI can get information direct out of this (relatively) simple database structure.
In LO, you can have an order with multiple deliveries to more than one delivery addresses. And the payer can also be different.
When 1 item (orderline) changes, this can have its reflection on order, supply, delivery, invoice, etc.
Therefore a special record structure is build for Logistical reports.and this structure now is used for BI.
In order to have this special structre filled with your starting position, you must run a set-up. from that moment on R/3 will keep filling this LO-database.
If you wouldn't run the setup. BI would start with data from the moment you start the filling of LO (with the logistica cocpit)
I hope I have been clear.

Hi Sonal
The kind of exractors largely depends on the application due to the way they were developed

Why we use crmd_link table ........?

Why we pass guid in guid_hi and get guid_set ? what is diffrent between them ?
Help will be rewarded ...
Regards
Gurprit Bhatia

A CRM transaction (e.g. contract) data info is not contained in a single table. We need to use different tables for the same.
guid_hi and guid_set are used for different categories of data like partner info, billing info, etc.
Some numeric ids are there for guid_hi and guid_set
Using help, u can find out which id stands for which category of data.

Why we use Cluster Tables in SAP Hr

hai friends, i am new to ABAP-HR and SAP HR, Actually i am core abaper ( working on SD, MM and Fi Modules ) , can any one explain me why and what is the use of Cluster tables in SAP HR, why we use in SAP HR function Module ?
Thnx in advance
Vijaya

Hi Vijaya,
This may help for ur question..
Why cluster table:
Cluster tables combine the data from several tables with identical (or almost identical) keys into one physical record on the database.
Data is written to a database in compressed form.
Retrieval of data is very fast if the primary key is known.
Cluster tables are defined in the data dictionary as transparent tables.
External programs can NOT interpret the data in a cluster table.
Special language elements EXPORT TO DATABASE, IMPORT TO DATABASE and DELETE FROM DATABASE are used to process data in the cluster tables.
PCL1 - Database for HR work area; (long text, etc)
PCL2 - Accounting Results (time, travel expense and payroll); (payroll results)
PCL3 - Applicant tracking data;
PCL4 - Documents, Payroll year-end Tax data (change logs, etc)

Why we use PCLn tables only in HR ?

Hii
Kindly explain me why we use special PCLn tables for storing data in data clusters ,This kind of storing data is not used in other modules such as SD MM etc why only in HR module ?
That too in cluster tables we store specific data like Payroll data why ?
Please help.
Thanks
Ajitabh Pradhan

Hi,
maybe ask directly SAP
Cluster table is not really usefull, I prefere transparent table for development. But, you have cluster table like STXL, STXBITMAPS, ... for special requierement.
Why do you want to use cluster tables ?

Statistical Setup Tables and Full Extractions

For Full Extractions what is the relationship with the statistical setup tables i.e. no of records in the table = no of records to be extracted? Thanks

Hi,
The relationship is 1 -> 1 you have to fill the setup table, the full load only reads this structure. So if you would like to load a 2LISxx full load every night, you have to delete and refill the setup table in R/3.
Kind regards, Patrick Rieken.

Why frameset? Why not use a table?

Why do we need to use the framesets?
I think that we should use the tables because the framesets
do not show you the border sizes and background colors on the
source (code window). The tables show you everything including the
background color codes so that you would know where to find it on
the source window. Although, a frameset is a big risk.
If you think that I'm wrong, then can you please explain it
to me. I respect your opinion.

You are right. Tables and/or css are preferable to a frames
layout.
Though I can understand why somebody would want to use
frames, certainly if
it is their first time out in web design. I myself was drawn
to the lure of
having that immutable left hand menu frame with my right hand
side being
able to change.
But then I discovered templates and server side includes.

Hi experts why we use set up tables in LO cockpit

please forward to my personal mail id
[email protected]

The logistic cockpit extractors are different from the others. They use setup tables and delta queues for initial loading and delta loading respectively. The delta queues act as a <i>buffer area</i> which is detatched from the business logic of the applications' operations (ref. <a href="/people/sap.user72/blog/2004/12/16/logistic-cockpit-delta-mechanism--episode-one-v3-update-the-145serializer146 COCKPIT DELTA MECHANISM - Episode one: V3 Update, the serializer</a>).
The other extractors read the application tables directly, both during the initial loading and during the delta loading. This means that whenever BW requests the data, a function module extracts the data from the R/3 tables.
I wonder why there is such a technological difference between the 2 classes of extractors. Could someone please shed some light on this? What considerations may have led to this kind of architectural choice? Is the number of transactions occurring in the applications covered by the LO extractors significantly greater than that occuring in other applications (e.g. FI, CO, etc.)? In this case, the ERP system could certainly benefit from a delta management buffer area.
Thanks&Regards, Davide

Missing PO in 2lis_02_itm init extraction / setup tables

Hello Gurus,
could anyone please help me out with this toppic:
I want to extract Purchase Orders to BW via DS 2lis_02_itm. Source System is R/3 4.6c. Filling up the setup tables is working. My problem is, that there are several Purchase Orders which are not filled in the setup tables (so no extraction to bw)! I have checked these PO and for me they seem fine. I can´t find any reason why they aren´t extracted. Of course i am running all programms whithout any restrictions. I have debugged the programm rmceneua with one specific po which is not extracted but can not find a reason why it is not written to table MC02M_SETUP.
Did i miss some customizing settings? Are there some kind of PO which are not extracted because of there PO Type (ZCO/ZB) do they eventually have a wrong status?
I can not find any information about the functionality of programm rmceneua. Maybe you can help me out of this?
Thanks a lot

Setup table in LO

Hi All
Why do we need setup tables in LO? Or What is the purpose of having setup tables in LO extraction?
Regards
Saddy

The purpose of the setup tables is to allow you the capability of loading historical data from R/3 to BW. You can use the setup tables for full loads or for establishing your initialization, but they are used independently of collecting delta data. Thus you can collect historical data for different applications (even different datasources within the same application) without affecting delta's already setup for other datasources.
Hope this helps.
