Difference Between Data type and message type

Hi,
i have doubt on data type and message type.why we are mapping the message type why not data type?wht is the difference between data type and message type?

Hi Narayanana,
Data type defines the structure of your xml message.Message type is the wrapper of data type.You will be using your message type while mapping and not the data type.Its the abstraction concept used in oops

Hi Suresh,
Data Type defines the structure of the message and it will be wrapped under Message Type.
Hope the details below will clearify your doubts.
A data type in a programming language is a set of data with values having predefined characteristics. Examples of data types are: integer, floating point unit number, character, string, and pointer.
The characteristic of columns and variables that defines what types of data values they can store.
Check out the details:

A message type comprises a data type that describes the structure of a message. At the following points in SAP Exchange Infrastructure you can refer to the message to be exchanged at runtime by using the message type:

Difference between IDOC Type and Message Type

Hi, please let me know the difference between IDOC type and Message Type?
Thanks

Hi,
Message type is business name for IDOC you are sending hiding all technical details of the IDOC.
IDOC type gives more technical information about structure of the IDOC.
You will be linking IDOC type to message type while processing IDOC in runtime. You will be specifying message type and IDOC type in WE20 trasaction which says which message will go to which partner whether it is outbound or inbound.

What is the difference between partner function and partner type

Hi Gurus,
What is the difference between partner function and partner type?
Thanks,
Paul

Hi John,
The partner types allow us to distinguish between different business partners such as customer, vendor, employee etc and the partner functions represent the functionality or role each partner plays within the business transaction.
For example under the partner type Customer, you will find - Sold to party, Ship to party, Bill to party, Payer.
The business partners that exist in the market place are represented with a partner type in the R/3 system. Examples of business partners are customer, vendor, employee and contact person.
The following partner types are defined in the partner processing for the sales & distribution module
a.     AP contact person (06)
b.     KU customer (07)
c.     LI vendor (08)
d.     PE employee/personnel (09)
Assigning the partner functions in the SAP system determines the functions of particular partner in the sales process. One partner may take on several functions also.

Resources for designing data types and message types

Hi
I wanted to know if anyone can recommend me some good resources which can explain the design considerations for designing data types and message types in XI which can help promote reusability.
Thanks.
Best Regards,
Kiran

hi,
there no rare rule whe you define your data type, why i tell you this, because you define a data type since the documentation that sender sistem team gives to you. so you only have to copy this structure to PI.
now about Message Type less problems, because, you a Data type is assign to a Message Type, whats it means.
when you define a DATA type you are defining the structure of you XML, que you assing the data type to a message type this structure pass to be an xml document.
Thanks you

What is difference between transport protocol and message protocol

what is difference between transport protocol and message protocol
please give definition and small explanation

Hi,
Transport protocol gives information about outside of message details, kind of system, security details.
A transport protocol is a network protocol that has the capability of transferring some payload from one node to another, thus providing some level of transparency from the underlying network.
Transport protocols are used as a mechanism to move payloads around a network. Typically, a payload will have a transport binding associated with it. For example, SOAP (acting as a payload) has a predetermined binding for HTTP (a transport protocol).
Some common transport protocols include: HTTP, HTTP-R, SMTP and BEEP.
Message protocol gives you an idea of message type XI payload

Idoc types and message types

Hi ,
Anyone can send what are all the std idoc types and message types are there in SAP?
Coz i dnt have SAP.
Please let me know

The IDoc type indicates the SAP format that is to be used to interpret the data of a business transaction.
An IDoc type consists of the following components:
·       a control record
This is identical for each IDoc type.
·       several data records
One data record consists of a fixed key part and a variable data part. The data part is interpreted using segments, which differ depending on the IDoc type selected.
·       several status records
These are identical for each IDoc type and describe the statuses an IDoc has already passed through or the status an IDoc has attained.
You find various IDOC / Message types in SAP -
http://www.erpgenie.com/sapedi/message_types_masterdata.htm
IDoc Types - Message Types -Accounting Business Processes

Difference between Data-centric and Document-centric use

Hi,
Can someone suggest what exactly is the difference between Data-centric and Document-centric use and examples if any.
Thanks in advance.
Chaitanya

Maybe it helps if you look at it this way...
Document centric: document centric use of xml data is data that you always use in its complete form. If you want to use the data, then you always will retrieve it as one entity or you save it as one entity. You are not interested in the xml data / information inside this "package" / document, you are only interested in its total form. Lets say, you have an invoice which can be printed on one sheet of paper. This paper that contains you data, will always be treated in a document driven way, that is, in its total representation: information containted on a sheet of paper (document).
Data centric. data centric use of xml, is usage of data were the main interest point is focused on only pieces of the total set of xml data within a document. So instead of being interested in the whole invoice, you only are interested in information like "amount of money to be payed" or "invoicenumber".
Handling of XML data comes with (hidden) costs. Knowing how your data will be used, has to be used, is one of the first steps in designing you environment (and will have an big impact if you choose poorly). For instance, if you know that your data will always be handled (and must be stored) in a document driven way, then it will make sense to store it based on CLOB based XMLType storage. This will garantee best performance retrieval for your xml document. If you now that your xml data has to be stored so that it can be handled in a data centric way, then Object Relational XMLType storage. If conditions are setup properly data retrieval, inserts and updates will be more cost efficient then when based on CLOB XMLType storage.
There are more differences and "cost markers" when or when not to use CLOB, OR or for instance Binary XML. The first two chapters of the XMLDB Developers Guide for Oracle 11g will give you a good head start making some of those decisions. Be also aware that you probably will have to make compromises. The current state of XML, for example, doesn't have the final solution yet for a uniform storage method.

Difference between Data staging and Dimension Table ?

Difference between Data staging and Dimension Table ?

Data Staging:
Data extraction and transformation is done here.
Meaning that, if we have source data in flat file, we extract it and load into staging tables, we take care of nulls, we change datetime format etc.. and after such cleansing/transformation at then end, load it to Dim/Fact tables
Pros: Makes process simpler and easy and also we can keep track of data as we have data in staging
Cons: Staging tables need space hence need memory space
Dimension Table:
tables which describes/stores the attribute about specific objects
Below is star schema which has dimension storing information related to Product, Customer etc..

Difference between Data Provider and extractor.

Hi
Can someone help me in understanding difference between data providers and data extractor.
I have gone through some documents but not able to get the exact difference between them.
What is the exact role of data provider and extractor with respect to sap solution manager.
Is data provider== Data extractor?
Thanks,
Vijay

Hello Vijaya,
From my perspective the Data Providers are responsible for collecting metric values from the monitored objects on the managed sources systems and sending these to the Solution Manager Monitoring and Alerting Infrastrucure.
Data extractors on the other hand are the reporting objects which are defined on the BW part of Solution Manager and can be enabled by configuring some monitoring scenario's. Once these data extractors are enabled, they will use the data from the "Data Providers" (see above) to setup nice BW reportings on the Solution Manager monitoring dashboards.
I hope this answer helps you.

Difference Between data target and infoprovider

Hi Experts,
I am new to BW
What is the difference between data target and infoprovider
Thanks and Regards,
saveen

Hi Saveen,
InfoProvider is an object on which BEx queries are created. It provides information (data) to the queries when they are executed. InfoProviders may contain data (like cube) or may not contain data (like multiproivder and InfoSet).
Data Target is an object to which you will load the data, like cube, ODS or InfoObject. But it is not necessary that each data target is an InfoProvider...like you may have ODS objects that are not enabled for reporting, but you are loading data to them for staging purpose.
Hope this helps...
