Difference between Asynchronous and synchronous service (BPMN Process).

When we create new BPM process jdeveloper gives 4 options including Asy and synchronous service.
i want to know how they differ logically because both templates look same!!!!

In an Async process the start node is exposed as 'one way', so if you see the wsdl for this (port type section) , you will see only inputs and not outputs. This means the caller doesn't wait for the process to end. In a Sync process, the web service interface to the start node is 'two way', request/response....so you will see both and input and output in the port type section. the caller will wait for the response from the process.

What is the difference between SmartNet and SMBS service level

Good Afternoon
I would like to ask if what is the difference between Cisco's SmartNet and Cisco's SMBS service level?
Thank you

Hi Rey,
SMARtnet covers traditional Cisco products (enterprise products ie. ISR routers), Small Business Support Center covers the small business line.
In the UC group of products, for some reason, Cisco considers the UC520, AP521, and WLC526 which are branded small business to be traditional Cisco products and are covered under SMARTnet. But, the UC540 and UC560 are covered by SBSC. One major difference in the UC arena is the support for CLI vs CCA config.
However, I noticed your post was in the Small Business - switches category. If you have a small business switch those are covered by SBSC not TAC. SBSC will support the CLI and web gui config of the small business switches, where CLI is applicable to the model.
SBSC contracts tend to be for 3 year periods and can be significantly less expensive than SMARTnet agreements.
Hope that helps.
Best,
David

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.

Clarification on differences between Gateway and Generic Services

Hi
I am trying to connect an MS SQL Server 7.0 on NT database to Oracle 8.1.7 Release 3.
Can I use the standard Oracle Heteregeneous Services OR do I HAVE to use the Transparent Gateway for SQL Server?
The documentation implies that the standard Hetegeregeous services bundled with 8i allow you to connect to any ODBC data source (although it constantly only makes reference to Access, Foxpro etc).
I have successfully connected to MS Access and MS Project using Oracle Heteregeneous Services but am running into problems connecting to MS SQL 7.0. (I cannot get the 8i listener to recognize the hsodbc service, I get an Ora-12154).
A definitive answer will be most appreciated.
Thanks,
Charles Farnell.

Thanks for your post. I have listed below my tnsnames.ora (partial), listener.ora (partial), inithsodbc.ora and database link DDL. I found a post on Metalink that says the SQL Server machine has to have the Oracle client installed, if this is the case then that could be my problem. Also, it mentioned the PORT in tnsnames.ora should be set to 1433 (the default port for SQL Server). I have tried 1521 and 1433.
If you could look at these and see if there are any obvious mistakes , I would be most grateful.

Differences between MIC and Process control

Hi
Could someone please let me know what are the major differences between MIC and process control 2.5.
I have heard that Process control 2.0 is not being used now.
So could you please let me know what the differences for MIC and Process control 2.5.
Regards
Sandhya

Hi Sandhya,
the major differences are:
- automated controls (SAP and non-SAP systems)
- UI interface based on NetWeaver Business Client (NWBC)
- flexibility on scheduling assessments and tests based on control attributes
- configurable reports and extraction to either .pdf or .xls
- possibility to se configure workflow to send reminders and escalations
- integration with Access Control 5.3, RAR component
- concept of service providers allowing controls to be referenced between different organizations (former MIC orgunit)
- assessments based on surveys (questions to be answered)
- effectiveness tests based on test plan (both tests and steps)

Difference between party and service

Hi,
I know when we are going to party and service (Normally party means. when we are doing Business to Business ) but what is exact difference between party and service.. and if possible definitions also..
Thanks
Babu.

Babu,
Refer to url http://help.sap.com/saphelp_nw04/helpdata/en/87/1d6e3fefa13042e10000000a114084/frameset.htm
An excerpt
Services without a party are typically used when configuring company-internal processes. Parties (with assigned services) are typically used when configuring cross-company processes.
Also refer to one of your previous forum questions and my response Re: Business System and Business Service Posted: Nov 28, 2007 4:31 PM in response to: BABU
You usually use business system services when configuring internal company processes.
You usually use business services when configuring cross-company processes. In this case, you only make your interfaces known to the business partners involved and either do not make any details about your own system landscape available, or only specific details.
Hope this helps,
Mike

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 Scheduled and released with respect to process chains

HI All,
I am Creating a cube in whcih I want to upload the current status of the process chain.
And the requirement is not to take those process chains whcih are scheduled and not released( only take those process chains whcih have status released)
for the same I dont know what is the difference between Scheduled and Released in respect of process Chains and also from whcih Database table I can get this information.
Please help.
Regards,
Ujjwal

Hi,
Job Status Scheduled means a job has been created and is ready to run but has not yet been triggered.
A release status means the created job has been triggered and is waiting for the opportunity to run. A job can be in released status when it is a periodic Job ( Where once the job is completed it goes to release status), when it is slated for future execution, or when there is a delay due to database overload.

Differences between rfc and ale/idoc.

hi ..
       will u please send the differences between rfc and ale/idoc's.

Hi,
Please reward with points if helpful................
ALE is SAP proprietary technology that enables data communications between two or more SAP R/3 systems and/or R/3 and external systems. There are three layers in ALE system: application services, distribution services, and communication services.
For communication services, ALE performs a Remote Function Call (RFC) using the port definition and RFC destination specified by the customer model. RFC is used to communicate between applications of different systems in the SAP environment includes connections between SAP systems as well as between SAP systems and non-SAP systems. Remote Function Call (RFC) is the standard SAP interface for communication between SAP systems. The RFC calls a function to be executed in a remote system.
Means of creating and operating distributed applications.
The purpose of Application Line Enabling is to guarantee a distributed, but integrated, R/3 installation. This involves business-controlled message exchange with consistent data across loosely linked SAP applications.
Application integration is achieved not via a central database, but via synchronous and asynchronous communication.
Application Link Enabling comprises the following three layers:
application services
distribution services
communication services
Two Development Models
     Distribution using BAPIs
     Distribution using Message type
The programming model "Distribution using message types" contains the definitions of message types and IDoc types and the ABAP code for processing inbound and outbound IDocs.
Defining message types and IDoc types:
If you want to create message type enhancements for master data distribution, you also have to create a new message type for each enhancement.
The ALE interface does not allow you to create different segment data for different IDoc types for the same message type.
Writing ABAP code:
         Outbound Processing
           Inbound Processing
You can find information on other ALE functions under:
                               Master Data Distribution
                              Communicating with Non-R/3 Systems
1. The Remote Function Call facility allows you to call an R/3 Function module on a remote machine.
2. To communicate between two R/3 Systems and also with an External System. External Application program also can call these function module for integration.
3. RFC or sRFC - Synchronous RFC
                 aRFC - Asynchronous RFC
                  tRFC - Transactional RFC
                  qRFC - Queued RFC (I.e. Serialization of tRFC)
Types of RFC Call
Synchronous
CALL FUNCTION Func Destination Dest
CALL FUNCTION func DESTINATION 'NONE' ...
CALL FUNCTION func DESTINATION BACK' ...
Asynchronous
CALL FUNCTION func STARTING NEW TASK taskname
PERFORMING form ON END OF TASK
RECEIVE RESULTS FROM FUNCTION func

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.

Differences between LSMW and BDC

Hi All
Please can you give me the few points about the differences between LSMW and BDC?
Awaiting for your Responce
Praveen

Hai Check with the following document
GOOD
THERE IS THREE TYPE OF METHOD IN BDC
BDC SESSION
CALL TRANSACTION
CALL DIALOG
What is BDC or batch input
The Batch Input is a SAP technic that allows automating the input in transactions. It lies on a BDC (Batch Data Commands) scenario.
BDC functions:
· BDC_OPEN_GROUP : Opens a session group
· BDC_CLOSE_GROUP : Closes a session
· BDC_INSERT : Insert a BDC scenario in the session
· The ABAP statement "CALL TRANSACTION" is also called to run directly a transaction from its BDC table.
It runs the program RSBDCSUB in order to launch automatically the session. The session management is done through the transaction code SM35.
The object itself is maintanable through the transaction SE24.
BDC methods:
Method
Description
Parameters
OPEN_SESSION
Opens a session
SUBRC (Return Code 0 OK)
SESSIONNAME (Session to be created)
CLOSE_SESSION
Closes a session
None
RESET_BDCDATA
Resets the BDC Internal Table...
None. Normally, for internal purpose
BDC_DYNPRO
Handles a new screen
PROGNAME (Name of the program)
DYNPRONR (Screen Number)
BDC_FIELD
Puts a value on the screen
FIELDNAME (Name of the field)
FIELDVALUE (Value to be passed)
CONSTRUCTOR
Constructor - Initializes NO_DATA
NODATA (No data character). The constructor is called automatically when the object is created.
RUN_SESSION
Launches a session with RSBDCBTC
None
CALL_TRANSACTION
Calls a transaction with the current BDC Data
MODE (Display Mode)
UPDATE (Update Mode)
TCODE (Transaction to be called)
BDC_INSERT
Inserts the BDC scenario in the session
TCODE (Transaction to be called)
BDC techniques used in programs:
1) Building a BDC table and calling a transaction,
2) Building a session and a set of BDC scenarios and keeping the session available in SM35,
3) Building a session and lauching the transaction right after closing the session.
BDC using Call Transaction
BDC using Call transaction involves calling an SAP transaction in back ground from within the ABAP
program. The process involves building an Internal BDC table containing the screen information needed to
execute the required transaction and then passing this to the Call transaction command (See code example).
The full procedure for creating a BDC program is as follows:
What is the difference between batch input and call transaction in BDC?
Session method.
1) synchronous processing.
2) can tranfer large amount of data.
3) processing is slower.
4) error log is created
5) data is not updated until session is processed.
Call transaction.
1) asynchronous processing
2) can transfer small amount of data
3) processing is faster.
4) errors need to be handled explicitly
5) data is updated automatically
BATINPUT/DIRECT INPUT
A: Batch-inputs can not be used to fill the "delivery due list" screen because it is not a dynpro. This is a standard SAP report. A SAP report (check with "System -> Status") may be called using SUBMIT sentence with the appropriate options . It is preferred to call a report than create a Batch-input program.

The LSM Workbench is an SAP R/3 based tool that supports the one-time or periodic transfer of data from non-SAP systems ("legacy systems") to SAP systems.
The LSM Workbench helps you to organize your data migration project and guides you through the process by using a clear sequence of steps.
The most common conversion rules are predefined. Reusable conversion rules assure consistent data conversion for different data objects.
LSMW vs DX Workbench
The LSM Workbench covers the following steps:
Read the legacy data from one or several files (e.g. spreadsheet tables, sequential files).
Convert the data from source format to target format.
Import the data using standard interfaces (Batch Input, Direct Input, BAPI, IDoc).
Experiences made in successful implementation projects have shown that using the LSM Workbench significantly contributes to accelerating data migration.
SAP provides this tool along with documentation to customers and partners free of charge.
Users of the LSM Workbench receive the usual support via SAP Net - R/3 Frontend (component BC-SRV-DX-LSM).
Releases:
Version 1.7.2 of the LSM Workbench ("LSMW 1.7.2") available
Attention : LSMW 1.7.2 requires an SAP R/3 system with SAP R/3 4.0 or SAP R/3 4.5.
Version 1.8.0 of the LSM Workbench (1.21mb) ("LSMW 1.8.0") available
Attention : LSMW 1.8.0 requires an SAP R/3 system with SAP R/3 4.6.
Version 3.0 of the LSM Workbench (1.89mb) ("LSMW 3.0") available for Web Application Server 6.10
Attention : LSMW 3.0 requires a SAP WAS 6.10. Functionality of version 1.7.2 and 3.0 are identical !
Version 4.0 of the LSM Workbench ("LSMW 4.0") integrated in Web Application Server 6.20
Attention : LSMW 4.0 is an integrated part of SAP WAS 6.20.

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.

Diff between asynchronous and syncronous posting

Hi,
Please may i know the difference between the asynchronous and synchronous posting in the FB60
regards
paveeee...

Dear Praveen,
Synchronous posting would update the database and would give you the message accordingly. For example, Dataabse updated successfully or not updated. Synchronous database update During processing, no transaction is started until the previous transaction has been written to the database.
Asynchronous posting would not update the database. It would not wait for the completion of updation process but would say the data is submitted for updation. You would not be sure whether the data is updated successfully or not updated.
Hence, Asynchronous update is faster as it would not wait for the database updation.
Regards,
Naveen.
