what is interface programming.? what is diff between bdc &bapi?
‎2007 Oct 12 3:27 PM
Prakash,
Interface programming means working with the interfaces... its also kind of data transfer like bdc...but much different from bdc and bapi.
Here you create one data transfere medium ( interface) with ale or edi.. and with the use of Idocs or files you tranfer the data between multiple systems by sydicating the systems or with out syndication.
where as in case of bdc its entirely different you get the data in the form of flat files into your location either into apps server or onto presntation server you will pick the data from there n upload the data or download the data to local file....
In interface programming also u can make use of BAPI's for the data transfer....

hi,
BDC : Batch data commuminication.
For a BDC upload you need to write a program which created BDC sessions.
Steps:
1. Work out the transaction you would use to create the data manually.
2. Use transaction SHDB to record the creation of one material master data.
Click the New recording button or the Menu - Recording - Create
3. Save the recording, and then go back a screen and go to the overview.
4. Select the recording and click on Edit - Create Program. Give the program a Z name, and select transfer from recording.
5. Edit the program. You will see that all the data you entered is hard-coded into the program. You need to make the following changes:
5.1 After the start-of-selection, Call ws_upload to upload the file (the excel file needs to be saved as TAB separated).
5.2 After the open-group, Loop on the uploaded data. For each line, perform validation checks on the data, then modify the perform bdc_field commands to use the file data.
5.3. After perform bdc_transaction, add the endloop.
Execute the program. It will have options to create a batch session or to process directly.
These are all my finds . Might be it will be useful to you.
Direct call of transactions, session handling:
/nxxxx This terminates the current transaction, and starts transaction xxxx
/n This terminates the transaction. This generally corresponds to pressing F15 to go back.
/nend This termiantes all separate sessions and logs off (corresponds to System - Logoff).
/nex This terminates all separate sessions and logs off immediately (without any warning!).
/oxxxx This opens a new session and starts transaction xxxx in This session.
/o This lists existing sessions and allows deletion or opening of a new session.
/i This terminates the current session (corresponds to System End
/i1, /i2,... This terminates the session with the number given.
.xyzw Fast path: 'xyzw' refers to the underlined letters in the menus. This type of navigation is uncommon and is provided more for emergencies (such as a defective mouse).
Batch
The following commands can be entered in correction mode ('Process in foreground' or 'Display errors only') when processing a batch input session:
/n This terminates the current batch input transaction and characterizes it as
/bdel This deletes the current batch input transaction.
/bend This terminates batch input processing and sets the session to Failed
/bda This switches from Display errors only to Process in foreground
/bde This switches from Process in foreground to Display errors only
ABAP/4
/h This switches into debugging mode.
/hs This switches into debugging mode and activates the debugging of system functions.
Buffer
WARNING: Resetting buffers can significantly change the performance of the entire system for a long time.
It should therefore only be used where there is a good reason tdso. As of release 3.0B system administator authorization is required (authorization object (S_ADMI_FCD). The action is noted in the system log.
/$SYNC This resets all buffers of the application server
/$CUA This resets the CUA buffer of the application server
/$TAB This resets the TABLE buffers of the application server
/$NAM This resets the nametab buffer of the application server
/$DYNP This resets the screen buffer of the application server

BAPI:
Methods
Parameters
Standardized BAPIs
Standardized Parameters
Important things to remember..
BAPI/ALE Integration
Methods
If the BAPI to be implemented is a standardized BAPI, use the generic names, for example, GetList, GetDetail.
The method name must be in English (maximum 30 characters).
The individual components of a BAPI name are separated by the use of upper and lower case.Example: GetList
Underscores ("_") are not allowed in BAPI names.
Each BAPI has a return parameter that is either an export parameter or an export table.
So that customers can enhance BAPIs, each BAPI must have an ExtensionIn and an ExtensionOut parameter.
Parameters
If standardized parameters are used, you have to use the names specified for standardized parameters.
BAPI parameter names should be as meaningful as possible. Poorly chosen names include abbreviations and technical names (e.g. "flag", table names, etc.).
The parameter and field names must be in English with a maximum of 30 characters.
The components of a parameter name in the BOR are separated by upper and lower case letters to make them easier to read. Example: CompanyCodeDetail
Values that belong to each other semantically should be grouped together in one structured parameter, instead of using several scalar parameters.
For ISO-relevant fields (country, language, unit of measure, currency), additional fields for ISO codes are provided.
Unit of measure fields must accompany all quantity fields and currency identifiers must accompany currency amount fields.
Standardized BAPIs
Some BAPIs provide basic functions and can be used for most SAP business object types. These BAPIs should be implemented the same for all business object types. Standardized BAPIs are easier to use and prevent users having to deal with a number of different BAPIs. Whenever possible, a standardized BAPI must be used in preference to an individual BAPI.
The following standardized BAPIs are provided:
Reading instances of SAP business objects
GetList ( ) With the BAPI GetList you can select a range of object key values, for example, company codes and material numbers.
The BAPI GetList() is a class method.
GetDetail() With the BAPI GetDetail() the details of an instance of a business object type are retrieved and returned to the calling program. The instance is identified via its key. The BAPI GetDetail() is an instance method.
BAPIs that can create, change or delete instances of a business object type
The following BAPIs of the same object type have to be programmed so that they can be called several times within one transaction. For example, if, after sales order 1 has been created, a second sales order 2 is created in the same transaction, the second BAPI call must not affect the consistency of the sales order 2. After completing the transaction with a COMMIT WORK, both the orders are saved consistently in the database.
Create( ) and
CreateFromData( ) The BAPIs Create() and CreateFromData() create an instance of an SAP business object type, for example, a purchase order. These BAPIs are class methods.
Change( ) The BAPI Change() changes an existing instance of an SAP business object type, for example, a purchase order. The BAPI Change () is an instance method.
Delete( ) and Undelete( ) The BAPI Delete() deletes an instance of an SAP business object type from the database or sets a deletion flag.
The BAPI Undelete() removes a deletion flag. These BAPIs are instance methods.
Cancel ( ) Unlike the BAPI Delete(), the BAPI Cancel() cancels an instance of a business object type. The instance to be cancelled remains in the database and an additional instance is created and this is the one that is actually canceled. The Cancel() BAPI is an instance method.
Add<subobject> ( ) and Remove<subobject> ( ) The BAPI Add<subobject> adds a subobject to an existing object instance and the BAPI and Remove<subobject> removes a subobject from an object instance. These BAPIs are instance methods.
BAPIs for Mass Data Processing
The BAPIs listed above for creating and changing data can also be used for mass processing. For more information see BAPIs for Mass Data Transfer [Extern]
BAPIs for Replicating Business Object Instances
Replicate( ) and SaveReplica( ) The BAPIs Replicate() and SaveReplica() are implemented as methods of replicable business object types. They enable specific instances of an object type to be copied to one or more different systems. These BAPIs are used mainly to transfer data between distributed systems within the context of Application Link Enabling (ALE). These BAPIs are class methods.
Other Less Used Standardized BAPIs
Programming GetStatus() BAPIs [Extern]
Programming ExistenceCheck() BAPIs [Extern]
Standardized Parameters
There are some parameters that can be created for various BAPIs because they contain the same or the equivalent data in all BAPIs. They should be implemented the same in all BAPIs.
Address parameters Specific reference structures are defined for address parameters in BAPIs. You should copy these structures to use in your BAPI, especially if the underlying object type uses the central address management (CAM).
Change Parameters In BAPIs that cause database changes (for example, Change() and Create() BAPIs) you must be able to distinguish between parameter fields that contain modified values and parameter fields that have not been modified. This distinction is made through the use of standardized parameters.
Extension parameters The parameters ExtensionIn and ExtensionOut provides customers with a mechanism that enables BAPIs to be enhanced without modifications.
Return Parameters Each BAPI must have an export return parameter for returning messages to the calling application. To provide application programmers with a consistent error handling process for BAPI calls, all return parameters must be implemented in the same, standardized way.
Selection Parameters Standardized selection parameters are used in BAPIs that can be used to search for specific instances of a business object type (e.g. in GetList() ). These parameters enable the BAPI caller to specify the relevant selection criteria.
Test Run Parameters The parameter TestRun is used in write BAPIs (Create() and Change() ), to check the entries for the object instance in the database before actually creating the object instance. The creation of the object instance is only simulated and data is not updated.
Text Transfer Parameters To transfer BAPI documentation texts (e.g. the documentation of a business object type), you have to create standardized text transfer parameters.
Important things to remember..
It is important to follow the guidelines below when develop9ng BAPIs:
BAPIs must not contain CALL TRANSACTIO or SUBMIT REPORT
BAPIs must not invoke a COMMIT WORK. instead use the BAPI TransactionCommit to execute the commit after the BAPI has executed.
BAPI structures must not use includes.
There should be no functional dependecies between two BAPIs
BAPIs must perform there own authorization check
BAPIs should not use dialogs
BAPIs must not cause the program to abort or terminate. re4levant messages must be communicated through the return parameter.
BAPI/ALE Integration
When you use the BAPIs for asynchronous messagning, the application in the sendig systen calls the generated ALE IDoc interface isntead of the BAPI.
Asynchronous BAPIs use the ALE interface this way:
Creates an IDOC from the BAPI data
Sends the IDOC to the target system
Receives the IDOC in trhe target system, crreates the BAPI data from the IDoc and calls the BAPI
An ALE interface for a BAPi is created in transaction BDBG.
Reward is usefull.
thanks.

Hi Prakash,
<b>BDC (Batch Data Communication)</b> is a technology used for data transfer. it is meant for transferring data thru SAP transactions itself. when u use BDC for data transfer, the sequence of steps is the same as when u use standard sap transaction screens for data upload. the only difference is that u can use different options for foreground/background processing.
<b>BDC:</b>
Batch Data Communication (BDC) is the process of transferring data from one SAP System to another SAP system or from a non-SAP system to SAP System.
<b>
Features :</b>
BDC is an automatic procedure.
This method is used to transfer large amount of data that is available in electronic medium.
BDC can be used primarily when installing the SAP system and when transferring data from a legacy system (external system).
BDC uses normal transaction codes to transfer data.
Types of BDC :
CLASSICAL BATCH INPUT (Session Method)
CALL TRANSACTION
BATCH INPUT METHOD:
This method is also called as CLASSICAL METHOD.
Features:
Asynchronous processing.
Synchronous Processing in database update.
Transfer data for more than one transaction.
Batch input processing log will be generated.
During processing, no transaction is started until the previous transaction has been written to the database.
CALL TRANSACTION METHOD :
This is another method to transfer data from the legacy system.
Features:
Synchronous processing. The system performs a database commit immediately before and after the CALL TRANSACTION USING statement.
Updating the database can be either synchronous or asynchronous. The program specifies the update type.
Transfer data for a single transaction.
Transfers data for a sequence of dialog screens.
No batch input processing log is generated.
For BDC:

<b>BAPI
BAPI stands for Business API(Application Program Interface).</b>
A BAPI is remotely enabled function module
ie it can be invoked from remote programs like standalone JAVA programs, web interface etc..
You can make your function module remotely enabled in attributes of Function module but
A BAPI are standard SAP function modules provided by SAP for remote access.
Also they are part of Businees Objest Repository(BOR).
BAPI are RFC enabled function modules. the difference between RFc and BAPI are business objects.
You create business objects and those are then registered in your BOR (Business Object Repository)
which can be accessed outside the SAP system by using some other applications (Non-SAP) such as VB or JAVA.
In this case u only specify the business object and its method from external system
in BAPI there is no direct system call. while RFC are direct system call.
Some BAPIs provide basic functions and can be used for most SAP business object types.
These BAPIs should be implemented the same for all business object types.
Standardized BAPIs are easier to use and prevent users having to deal with a number of different BAPIs.
Whenever possible, a standardized BAPI must be used in preference to an individual BAPI.

In SAP, Interface means any program that provides the Communication with External (SAP or Non SAP) system.
Interface techniques are:
BAPI
RFC
ALE / IDOC
EDI
<b>bdc &bapi</b>
<b>BAPI</b>
BAPI stands for Business API(Application Program Interface).
A BAPI is remotely enabled function module
ie it can be invoked from remote programs like standalone JAVA programs, web interface etc..
You can make your function module remotely enabled in attributes of Function module but
A BAPI are standard SAP function modules provided by SAP for remote access.
Also they are part of Businees Objest Repository(BOR).
BAPI are RFC enabled function modules. the difference between RFc and BAPI are business objects.
You create business objects and those are then registered in your BOR (Business Object Repository)
which can be accessed outside the SAP system by using some other applications (Non-SAP) such as VB or JAVA.
In this case u only specify the business object and its method from external system
in BAPI there is no direct system call. while RFC are direct system call.
Some BAPIs provide basic functions and can be used for most SAP business object types.
These BAPIs should be implemented the same for all business object types.
Standardized BAPIs are easier to use and prevent users having to deal with a number of different BAPIs.
Whenever possible, a standardized BAPI must be used in preference to an individual BAPI.

<b>BDC:</b>
Batch Data Communication (BDC) is the process of transferring data from one SAP System to another SAP system or from a non-SAP system to SAP System.
<b>Features :</b>
BDC is an automatic procedure.
This method is used to transfer large amount of data that is available in electronic medium.
BDC can be used primarily when installing the SAP system and when transferring data from a legacy system (external system).
BDC uses normal transaction codes to transfer data.
<b>
Types of BDC :</b>
CLASSICAL BATCH INPUT (Session Method)
CALL TRANSACTION
<b>BATCH INPUT METHOD:</b>
This method is also called as CLASSICAL METHOD.
Features:
Asynchronous processing.
Synchronous Processing in database update.
Transfer data for more than one transaction.
Batch input processing log will be generated.
During processing, no transaction is started until the previous transaction has been written to the database.
CALL TRANSACTION METHOD :
This is another method to transfer data from the legacy system.
<b>Features:</b>
Synchronous processing. The system performs a database commit immediately before and after the CALL TRANSACTION USING statement.
Updating the database can be either synchronous or asynchronous. The program specifies the update type.
Transfer data for a single transaction.
Transfers data for a sequence of dialog screens.
No batch input processing log is generated.

BDC is a simulation of ABAP Transaction (SAP object)..where as in BAPI we input data and entry for SAP object goes directly to SAP database..
in short BAPIS are APIs for SAP buisness object
