Difference between master and transaction data

whts the difference and relaionship between master data and transaction data?why do we need to upload or extract both type of data's?cant we have only transaction data?please clarify

Hi ,
Master Data :
The data which do not change frequently and that is needed generally for many reporting .
Eg : Customer Name , Customer Address Etcc..
Transaction Data :
This the data that is derived based on some master data
Eg : Creating a sales order for a Customer . So the transaction data will be
 Customer Number , Order Quantity .
Why we keep master data as seperate in BW ?
Because master data is general , So we have to use that master data in many cubes for reporting purpose . Because for any report on Customer we need to give cutomer name , So we keep that master data outside of cube so that any cubes that need to use customer master can take that , So we can concentrate on other dimensions for cube ,Other wise we need to include customer name in all cubes which is reppetitive .
So the best method is to ....
First Load master Data
Then load Transactio data .
In the Bex part we combine the master data with transaction data so that we get combined data .
Eg :
Master Data : Customer No , Cust Name , Cust Address
Tran Data : Customer No , SD No , Order Qty .
We first load the master data into master data tables /BI0/M*
Then we load tarnsaction data into Cubes .
Then in BEX Reporting we create query for Transaction Cube , But fetch some master data using Bex feature , So the report output will be
Cust No CustName CustomerAddress SD no Order Quantity
Hope this Solves your Problem

Relation between master and transaction data

Hi experts,
I have a basic question how the relation between masterdata and transction data is maintained in R/3. As I know first we extract master data and later transaction data in a typical R/3 based scenario.
1.How does BW knows that , the transaction data are related masterdata in the same sense as in R/3 ?
I am involved in an enhancement of R/3 extractor. I need to derive 3 more fields and map it to info objects in BW. Cld any one explain me ( with an example plz) how these alignments to be made. How can I establish relation b/w derived fields and transaction data during extractions ?

D Bret

Hi Dave.
Let's see if I can get all of your questions answered. First, when Transactional Data is loaded, BW checks to see if a SID exists for each characterisatic field & value in the load. If one doesn't, it either creates a SID (Surregate ID) in the master data tables (default action) or the load fails (if the enforece referential intgegrity flag is set). It's better to load master data first in either case as it will improve the performance of the transactional load.
In terms of R/3, the data has similar relationships as in BW. There are master data tables and transactional data tables. The difference is that while R/3 uses ~1 master data table per field, BW uses more. Same thing for transactional data.
As for your enhancement, if everything you need for the derivation of the extra field is in R/3, then you can enhance the extractor in RSA6 and do the mapping in R/3. Once you replicate the DataSource to BW and reconnect the transformation & update rules, the load should work. If you can give a bit more information on what sort of enhancement you are attempting, I can give a better example.

Difference between 0FI_AP_30 and 0FI_AP_4 Data source

HI,
What is the difference between 0FI_AP_30 and 0FI_AP_4 Data source.
Thanks in advance

Hi,
In addition to above differences. Below is the functional difference between 0FI_AP_30 & 0FI_AP_4:
0FI_AP_4 gives you accounts payable line items in your report. Here GL account shows the balances of particular types of vendors/payables to which that particular GL account is been assigned.
And If subledger is activated in ECC, then by using 0FI_AP_30 you can get the break up of that particular GL balance according to vendors.
To make use of datasource 0FI_AP_30, subledger accounting must be activated in ECC.

Pradip

What is wrong?
Please help me.I need Data to make a demo planning
thanks

Hi,
There is a set of objects in business content (check under SAP DEMO in business content). You can activate some or all of these demo objects (for example demo cubes).
There are programs which you can then execute to create the datafiles which can then be loaded to these demo cubes.
" Start report RSO_BC_FILES_IN_BDS (Transaction SE 38), specify the required (Demo) InfoObject/InfoCube and choose the "Start BDN" button. The system will display all (generally one) CSV files which were supplied with the InfoObject/InfoCube. You can either export this CSV file into a local directory or you can write it directly onto the application server. For loading, proceed as described under section 1. " --- from OSS note 370397

Transfering Master and Transaction data to active and non active versions

Hi Gurus,
I am planning to transfer ECC master and transaction data to APO active and simulation versions.My question is
1. Is it possible to release Master and transaction data to active and non active versions ?
2. How i need to config if i want to release Master and Transaction data in version 001?
Please let me know .
Thanks in Advance
Regards,
Raj

Hi Raj,
1) Once you create active integration models for master data and
transactional data, the data will get updated in active version 000
2) For creation of non active version use transaction
/SAPAPO/MVM
3) For copying of data from active to non active version, use
transaction /SAPAPO/VERCOP

Difference between passive and active data connection mode for FTP

Hi,
Does any body have the idea of passive and active data connection mode for the transport protocol FTP.
I have one server with FTP, I have to pick the data from this FTP to XI.
What is the difference between active and passive data connection? Does XI supports both the connections?
Thanks & Regards
Katta Mohan Reddy

Hi
According to SAP Note - 821267
Q: Does the File Adapter support active data connections when connecting to an FTP server?
A: Up to and including SP14, the File Adapter exclusively uses passive data connections. Starting with SP15, active connections will be available.
Difference between active and passive,
You can definitely refer to the site mentioned by Suraj

What is master and transaction data

can any one explain me in detail about the Master data and Transaction data.

Transaction data is data related to a single business event such as a purchase requisition. For example, when you create a requisition, SAP creates an electronic document for that particular transaction. SAP gives the transaction a document number and adds the document to the transaction data that is already in the system.
Master data is a collection of information about a person or an object, e.g. vendor or G/L account. For example, a vendor master record contains not only general information but also purchase order related information. Master data can only be entered and changed by authorized users.

Difference between SXPG_COMMAND_EXECUTE and Open data set mechanism

Can you please help me to know the difference between moving a file using FM "SXPG_COMMAND_EXECUTE" and moving file using "open data set - transfer file- close data set" mechanism?

Through 'SXPG_COMMAND_EXECUTE' u can execute a External command (ie.. UNIX /Windows/OS/400) In ABAP programming..
for Conversion Of Aplication server File/Move the file from one directory to Other...
The Command must be present in SM69.
Using this function module'SXPG_COMMAND_EXECUTE' , you can check the authorization of a user to execute a particular external command and run the command:
With the arguments specified in ADDITIONAL_PARAMETERS
On the target host system defined by OPERATINGSYSTEM and TARGETSYSTEM
If an SAP profile parameter is inserted in the portion of the command stored in the database, then the value of this parameter is substituted into the command. If an SAP application server is active on the target system (TARGETSYSTEM), then the profile parameter values are read from the profile that is active on that system. No parameter substitution is made in ADDITIONAL_PARAMETERS.
After substitution, the command is checked for the presence of "dangerous" characters such as the semicolon ( ; ) on UNIX systems.
If an additional "security function module" is specified in the command definition, this function module is also called in the course of processingebenfalls. This function module can prevent execution of the command.
If the authorization checks complete successfully, the command is run on the target host system.
Through Open Data Set u can read and write the file in the same directory...

SD

Delete ERMS master- and transaction data

Hi all,
I was wondering if it is possible and if so, how, to physically delete emails. So not only setting some sort of status, but actually delete the emails including the attachments etc. belonging to these emails. Is it possible via a (simple) transaction were one can do a search and delete, or via the WebClient itself, or....whatever.
We're about to quit using ERMS, and as a consequence, we would like to clean up everything related to ERMS like master data, transaction data and customizing.
Kind regards,
Micky.

Hello Micky,
Unfortunately there does not seem to be a good solution for archiving ERMS / Agent Inbox emails that come in via SAP Connect interface. As you probably know, once an email arrives via SAP Connect, the email is converted into an SAP workflow workitem. Once the email is processed from the IC Agent Inbox, the workflow item is completed and the email is converted into an SAP Office document. From what I have heard, there is a possibility to do a "reorganization" in SAP Office to get rid of the SAP Office documents. I have also heard that customers have had success archiving the completed SAP workflow workitems. In case you are interested I think the tables that are used for ERMS related SAP Office documents are SOFM, SOOD, SOC3, SOFFCONT1 (if it is binary data), SOOS, SOST, and SOES (send external).
The issue rather seems to be that there is no possibility to archive the attachments of the SAP Office documents! My recommendation is to store the attachments on an external content management server as described in SAP note 904711. I am aware of a few other obscure reports (e.g., report RSSOAPUT) that are supposed to archive certain types of attachments (i.e., RAW and SCR), but I haven't heard of any customers who have successfully used these programs so I don't recommend them.
Best regards,
John

What is master data and transactional data?

Hi abapers,
I want to know the difference between master and transactional data?. What is the significane of both master and transactional data. At what situation master data is used, and at what situation transactional is used?. Please give me example of tables using them.

Master Data:
Master data is data that remains unchanged over a period of time. It contains information that is always needed in the same way. For example, all personal attributes can be stored in various SAP standard infotypes as records with specific validity which are called Master data.
Master data are the critical nouns of a business and fall generally into four groupings: people, things, places, and concepts. Further categorizations within those groupings are called subject areas, domain areas, or entity types. For example, within people, there are customer, employee, and salesperson. Within things, there are product, part, store, and asset. Within concepts, there are things like contract, warrantee, and licenses. Finally, within places, there are office locations and geographic divisions. Some of these domain areas may be further divided. Customer may be further segmented, based on incentives and history. A company may have normal customers, as well as premiere and executive customers. Product may be further segmented by sector and industry.
Transaction data:
Data relating to the day-to-day transactions.
Reward if helpful.
Thanks.

Difference between master cost centre and sender cost centre

Hi All,
could you please tell the difference between master and sender cost centre.
I want this information very urgent.
Thanks rakesh

Hi!
The master CT is a default Ct in your system.
In this case the logical pair for master is the "child" cost center -> primary and secondary cost centers..
The sender CT is a different thing logically -> this will be credited while posting. The sender is the one who claims money.
To this type the logical pair is the receiver cost center. While posting the receivers cost center will be debited.
Hope this helps!
Best regards,
Zsolt

Difference between BIW and BPS

Hi All,
Please give me brief overview of BPS and tell me the difference between BPS and BIW.
Regards,
Vaishali.

hi vaishali ,
BPS is Buisness Planning & Simulation
whereas BIW -Buisness Information Warehouse.
The difference between them is diffrence of pupose
The BIW is use to store large amount of Enterprice data according to module collected from various source systems & provide it in summarised form to various analytical applications the BIW stores data in the manner that it can be easily retrieved and displayed to end user in for analysis .
the reports may be generated in excel format or as web page .
the basic idea behind BW is that the data stored in warehouse in in detailed format and if used for reporting directly causes performance issues
Now for BPS It is a planning application . ie it provides environm,ent for creating planning applications like Balance sheet planning budgeting ,Investment planning etc.
the BIW store Master And transaction Data( actual data )
the Planning data is Entered through BPS into what we call as transaction cubes . we can also use actual data do some forecasting on it( apply planning functions on it and store it as plan data this plan data can be used for further reporting purpose by the enterprice.
Hope this clarifies you doubt
