What is BDC session method in SAP ABAP?
BDC Session Method is used to upload data from Non-SAP to SAP System. Using Session method, we can transfer data through more than one Transaction, Unlike BDC Call Transaction Method Program. We are Processing Batch input Session From SM35 Transaction Code. 2) can transfer a large amount of data.
What is the difference between BDC session and call transaction method?
Difference Between CALL TRANSACTION and SESSION METHOD Call transaction does the Data consistency check with the help of screen logic. The system executes a database commit immediately before and after the ‘CALL TRANSACTION USING’ statement whereas for the sessions method it goes for Asynchronous processing.
Which function modules are used in BDC session method?
BDC_INSERT: This function module is used to transfer the data from BDCDATA structure into the session. Just call the function module and provide the transaction code name and BDCDATA internal table name.
Is BDC session method synchronous or asynchronous?
A BDC performed with sessions is always synchronous. In asynchronous processing, the program that outputs the statement COMMIT WORK does not wait that means the system returns control after merely logging the request for execution.
What program releases BDC sessions?
RSBDCSUB is used for executing BDC sessions, e.g. you create BDC sessions in a user exit and want to execute them once every day. You can schedule RSBDCSUB to execute you BDC sessions at a particular time.
How does BDC work in SAP?
There are three steps to upload data through BDC Session Method, those are,
- Create Session – calling Function Module ‘BDC_OPEN_GROUP’ you open session.
- Insert Data – in Session from IT_BDCDATA using Function Module ‘BDC_INSERT to insert Screens, Fields and Values.
- Close Session – using Function Module ‘BDC_CLOSE_GROUP’.
Which is better BDC or BAPI?
BAPI is directly updated the database instead BDC run through the screen flow. So BAPI can’t handle all the flow logic checking and enhancement put by programmer to faciliate the user requirement. Difference between BAPI and BDC: BAPI is a higher end usage for tranfering the data from SAP to non-SAP and vice-versa.
Why BDC is used in SAP?
BDC sessions, which are also known as Batch Input Sessions, are used to load legacy data into the SAP system and perform highly repetitive tasks that involve in data entry. BDC session simulates the online entry of all data, transactions, validations that are included in each transaction.
How do you handle errors in BDC session method?
Unlike Session method,error handling is not done by the system in CALL TRANSACTION method. So,in call transaction method error handling is done by using the BDCMSGCOLL structure. The error messages are collected into an internal table for messages(say it_message) which is of type structure BDCMSGCOLL.
What are the types of BDC in SAP ABAP?
Types of BDC (Batch Data Communication) in SAP ABAP
- Types of BDC (Batch Data Communication)
- CLASSICAL BATCH INPUT (Session Method)
- CALL TRANSACTION METHOD :
What is BDC session?
What is BDC programming in SAP?
Identify the screens of the transaction that the program will process.
What is SAP session?
Session Announcement Protocol (SAP) is an experimental protocol for broadcasting multicast session information. SAP was published by the IETF as RFC 2974. SAP typically uses Session Description Protocol ( SDP ) as the format for Real-time Transport Protocol session descriptions.
What is a batch input in SAP?
Introduction to Batch input. Batch input is typically used to transfer data from non-R/3 systems to R/3 systems or to transfer data between R/3 systems. It is a data transfer technique that allows you to transfer datasets automatically to screens belonging to transactions, and thus to an SAP system.
