Differences between webservice and proxy

Hi guys.
Which are the differences between webservices and proxys?
If I have a XI adapter (proxy) or Soap Adapter in Pi in both a Proxy Abap is created in SEECC to consume the service so I cant see the differences...
Regards

If I wanted to consume a webservice exposed in Pi by a Sender SOAP Sender, what would I have to do?
Nothing exceptional.....just define a message structure in PI....create a message interface....generate a WSDL for this Message Interface.....use the URL from this WSDL to send message.....it is a normal SOAP --> XI scenario.....many references are readily available on How to do this.

What is the Difference Between Adapter and Proxy

Hi Master,
I want to know the Difference Between Adapters and Proxies.
And when we are using proxies and Adapters....
Regards,
SReddy

Adapters are part of the Adapter Framework. Adapters provide the technical connectivity to enable the integration of SAP and non-SAP applications through XIs Integration Engine.Again, Adapters are used for connectivity from and to external systems with XI that cannot communicate via proxies.Adapters are only required in SAP systems older than 6.20 and external systems.
Systems based on 6.20or higher can communicate directly with proxies.
The literal definition of a proxy is an object / process authorized to act for another; an agent or a substitute. In simpler terms, proxies in the XI context are objects used to encapsulate the creation (from a sender system) or parsing of XML (at a receiver system) as well as the communication with the relevant runtime components required to send or receive those messages.
Proxies are generated from Message Interface in IR.
The Proxy Runtime controls these objects / processes, and can itself be controlled by the applications it communicates with. The Proxy Runtime currently has the following components available: 1. ABAP Proxy Runtime Communication using XI or Web Services a. Web Service Runtime 2. Java Proxy Runtime Communication using XI (J2EE) The objects that the Proxy Runtime then controls are created via Proxy Generation, for both ABAP and Java. In the following sections a client proxy is used by an application to send messages outside of the system it resides in (normally to the IS in this context). Conversely, a server proxy is used by an application to receive messages from sources outside itself (again, normally the IS in this context).

Difference between Webservice and RFC

Dear Experts,
We have an application to implement where the application will be called from other NON SAP technology. We got two solutions one is developing RFC's and calling it from other NON SAP Technology OR developing Webservice. Could any one please suggest us to which way do we need to choose?
Regards,
Gopinath A.

That's more or less up to you. In a nutshell: RFC is a known SAP technology for communication between SAP and (NON) SAP systems (both ways, inbound and outbound). Communication is set up quite easily (check SCN for that, work for Basis Administrator).
From an RFC, you can get to a WebService within a few clicks. RFC is basis of a webservice, which is based on known (internet) standards.
You decide, together with NON-SAP system (can it consume or provide RFC requests, or webservices for that matter) and basis administrators.
You can find a lot of info in SCN on both methods about architecture etc. This should help you decide.

Difference between Webservice and Enterprise Service

Hi all,
In SAP, web service is known as Enterprise Service. What makes Enterprise Service different from a normal web service?

Hi,
Enterprise Service is a web service with business semantics.
The tecnology is same i.e HTTP,SOAP,WSDL.
But there are some governance rule for defining an Enterprise Service and it can be defined only in ESR(using business objects, process components etc).
There are no such governance rule for defining a web service. You can simply write a mehtod/functional module to add two nos and expose it as a web service . But would not be called as Enterprise Service.
Hope this helps.

Difference between webservices model and adaptive webservices model

hi
Can any one explain me regarding Difference between webservices model and adaptive webservices model.
Thanks

Hi,
In old WS Model, ithere was no concept of logical destinations.
There if you are using a WSDL located on a server and if the location of the WSDL
changes, your application won't run. The deployed application using the WS Model will have trouble finding
the WSDL. As a result you'll have to again import the
model. Moreover old WS Model does not have re-import functionality.
But incase of AWS Model, you can desine logical destinations and even if the location of the WSDL changes, all you have to do is change the new url in the Visual Admin and not import the model again.
You can visit the following link for more details:

Hi Ravi,
Jin has correctly explained.
Only two connectors are provided from SAP
JCO- for connecting java applications
>.Net connectors - for connecting >net applications
And SAP has provided these connectors bcoz these the two most popular technologies or framefork these days which are very common.
But In my previous examples , I try to explain the concepts only by giving .net as example.
Now for making you clear, No SAP connector is available for C++ for accessing RFC but C++ can access web services using XML and SOAP
Again Note these points.
RFC is SAP specific.
Used For----->
SAP applications- SAP applications
SAP Appl - Java Applications(Using JCO)
SAP Applications->Net Applications( using >NEt connectorprovided by SAP)
Web Service is open standard
Any Platform/Any Language to Any Platform/Language( which can understand SOAp and XML).

What's the difference between Routing and Service Callout in ALSB?

I am puzzled by that.
what's the difference between them.
Or what's the situation should use Routing, and that of service callout?

There is little difference between routing and service callout.
Routing is symbolizes the transition of request thread to a response thread starts. (in OSB every invocation of proxy is undertaken by different request and response threads ). So by this definition, there can be only one route node in a pipeline.
Service call out is also used for similar actions as route node , but in pipeline. So service callout can be either in request pipeline (request thread) or in response pipeline (response thread ) . So in a proxy you can have multiple ServiceCallouts but only one route node.
There are some other slight differences.

Difference between idoc and rfc

what is the difference between idoc and rfc? when and where it is used? when there is idoc, why rfc vice versa?

IDoc (for intermediate document) is a standard data structure for electronic data interchange (EDI) between application programs written for the popular SAP business system or between an SAP application and an external program. IDocs serve as the vehicle for data transfer in SAP's Application Link Enabling (ALE) system.
IDocs are used for asynchronous transactions: Each IDoc generated exists as a self-contained text file that can then be transmitted to the requesting workstation without connecting to the central database.
Another SAP mechanism, the Business Application Programming Interface (BAPI) is used for synchronous transactions.
A large enterprise's networked computing environment is likely to connect many geographically distributed computers to the main database. These computers are likely to use different hardware and/or operating system platforms. An IDoc encapsulates data so that it can be exchanged between different systems without conversion from one format to another.
IDoc types define different categories of data, such as purchase orders or invoices, which may then be broken down into more specific categories called message types. Greater specificity means that an IDoc type is capable of storing only the data required for a particular transaction, which increases efficiency and decreases resource demands.
An IDoc can be generated at any point in a transaction process. For example, during a shipping transaction process, an IDoc may be generated that includes the data fields required to print a shipping manifest. After a user performs an SAP transaction, one or more IDocs are generated in the sending database and passed to the ALE communication layer. The communication
layer performs a Remote Function Call (RFC), using the port definition and RFC destination specified by the customer model.
The IDoc is transmitted to the receiver, which may be an R/3, R/2, or some external system
RFC
Remote Function Calls (RFC) and data exchange through IDoc message documents. RFC makes direct and synchronous calls of a program in the remote system. If the caller is an external program it will call an RFC-enabled function in R/3 and if the calling program is the R/3 system it will call an RFC-function in another R/3-system or it will call a non-R/3 program through a gateway-proxy (usually rfcexec.exe). BAPIs are a subset of the RFC-enabled function modules, especially designed as Application Programming Interface (API) to the SAP business object, or in other words: are function modules officially released by SAP to be called from external programs.
note:reward points if solution found helpfull.....

What is the difference between rfc and idoc

hi,
My name is rambabu.can anyone of u please tell me the main differences between idoc and rfc??
Thanks in Advance

hi Ramesh,
Remote Function Calls (RFC) and data exchange through IDoc
message documents. RFC makes direct and synchronous calls of a program in
the remote system. If the caller is an external program it will call an
RFC-enabled function in R/3 and if the calling program is the R/3 system
it will call an RFC-function in another R/3-system or it will call a
non-R/3 program through a gateway-proxy (usually rfcexec.exe). BAPIs are
a subset of the RFC-enabled function modules, especially designed as
Application Programming Interface (API) to the SAP business object, or in
other words: are function modules officially released by SAP to be called
from external programs.
IDocs are text encoded documents with a rigid structure that are used to
exchange data between R/3 and a foreign system. Instead of calling a
program in the destination system directly, the data is first packed into
an IDoc and then sent to the receiving system, where it is analyzed and
properly processed. Therefore an IDoc data exchange is always an
asynchronous process. The significant difference between simple RFC-calls
and IDoc data exchange is the fact, that every action performed on IDocs
are protocolled by R/3 and IDocs can be reprocessed if an error occurred
in one of the message steps.
While IDocs have to be understood as a data exchange protocol, EDI and ALE
are typical use cases for IDocs. R/3 uses IDocs for both EDI and ALE to
deliver data to the receiving system. ALE is basically the scheduling
mechanism that defines when and between which partners and what kind of
data will be exchanged on a regular or event triggered basis. Such a
set-up is called an ALE-scenario.

Difference between streaming and chunking

Hi,
I am working in a secure proxy project. Already we implemented chunking funcionality. Chunking meas when client accessing a big file- no need to wait until the total page downloaded(we generally observe status bar to say request is in processing). Depending on the specified chunked size, output will display onto client browser in chunks...
Now the requirement is to implement streming....
But we r not sure..what is the exact difference between Streaming and chunking.....Will any one give some inputs or ideas....
Thanks,

Difference between IntegrationServer and Integration Engine

Hi,
Could you please provide me difference between IntegrationServer and Integration Engine.
functionality of both and what are the runtime environments exits in XI Server.
Could you please show me digaram how message flow from
XI server i.e., through which engines.. what is the input and output of each engine.
Thanks,
RamuV

Hello Ramu,
Go through this link..

Use
Two SAP XI 3.0 Integration Servers are used to exchange messages between the system landscapes of two business partners.
Description
An SAP XI Integration Server of a business partner is connected to the SAP XI Integration Server of another business partner. Both use SAP XI message protocol to send or receive messages.
When an SAP XI Integration Server receives a message from another Integration Server it understands the message format and so processes the message.
Example
A business partner that uses SAP XI wants to send a message to another business partner who also uses SAP XI .
·        The message is sent between the Integration Servers in SAP XI message format
·        The Integration Server of the second business partner then sends the message to the relevant business system
Integration Engine
Purpose
The Integration Engine enables you to process XML messages exchanged between applications in heterogeneous system landscapes. Both applications of SAP components and external applications can communicate with the Integration Engine.
Using adapters, the Integration Engine can also process IDocs (Intermediate Documents) and RFCs (Remote Function Calls). This option is available for applications that have already defined IDocs or RFCs, as well as for applications of SAP components that do not yet have access to the proxy generation functions.
Integration
The Integration Engine is the runtime environment of the SAP Exchange Infrastructure. The following are examples of other important parts of this infrastructure:
·        Proxy Generation
·        Integration Repository
·        Integration Directory
The integration processes involved can take place between heterogeneous system components within a company, as well as between business partners outside company boundaries.
Features
The Integration Engine, as a runtime component of SAP Exchange Infrastructure, has the task of receiving, processing, and forwarding XML messages. During message processing, collaboration agreements are evaluated, the receivers are determined, and mapping activities are executed.
The individual processing steps are called pipeline services and are defined in pipelines. It is the task of the Integration Engine to process these pipelines correctly and consistently. To guarantee this, you must configure the Integration Engine accordingly and monitor the message processing. Both event-driven message processing and prioritized message processing are possible.
Thanks,
Satya Kumar

Difference between Null and null?

What is the difference between null and NULL?
When is each used?
Thanks,

veryConfused wrote:
There is a null in java, but no NULL. null means no value. However, when assigning value, the following is different:Although the empty String has no special role. Null means, the referential type is not assigned (doesn't refer) to a specific object. The empty String is just another object though, so seeing it or pointing it out as something special when it actually isn't at all (no more special than new Integer(0) or new Object[0]) just adds to the confusion.

Difference between GUI_UPLOAD and WS_UPLOAD

Hi,
Please make me clear about the difference between GUI_UPLOAD and WS_UPLOAD. In which cases we need to use these modules...??
Thanks,
Satish

I would suggest to always use the GUI_UPLOAD. I say this because this is the function module which is used in the GUI_UPLOAD method of the class CL_GUI_FRONTEND_SERVICES.   Really, you should probably use the class/method instead of the function module.
data: filename type string.
filename = p_file.
call method cl_gui_frontend_services=>gui_upload
         exporting
              filename                = filename
              filetype                = 'ASC'
         changing
              data_tab                = iflatf
         exceptions
              file_open_error         = 1
              file_read_error         = 2
              no_batch                = 3
              gui_refuse_filetransfer = 4
              no_authority            = 6
              unknown_error           = 7
              bad_data_format         = 8
              unknown_dp_error        = 12

Difference between char and varchar, also the difference between varchar2

Hi,
Can anyone explain me the difference between char and varchar, and also the difference between varchar and varchar2...

Varchar2 is variable width character data type, so if you define column with width 20 and insert only one character to tis column only, one character will be stored in database. Char is not variable width so when you define column with width 20 and insert one character to this column it will be right padded with 19 spaces to desired length, so you will store 20 characters in the dattabase (follow the example 1). Varchar data type from Oracle 9i is automaticlly promoted to varchar2 (follow example 2)
Example 1:
SQL> create table tchar(text1 char(10), text2 varchar2(10))
2 /
Table created.
SQL> insert into tchar values('krystian','krystian')
2 /
1 row created.
SQL> select text1, length(text1), text2, length(text2)
2 from tchar
3 /
TEXT1 LENGTH(TEXT1) TEXT2 LENGTH(TEXT2)
krystian 10 krystian 8
Example 2:
create table tvarchar(text varchar(10))
SQL> select table_name,column_name,data_type
2 from user_tab_columns
3 where table_name = 'TVARCHAR'
4 /
TABLE_NAME COLUMN_NAME DATA_TYPE
TVARCHAR TEXT VARCHAR2
