What is batch data communication?
Batch Data Communication or BDC is a batch interfacing technique that SAP developed. It is mainly used for uploading data into the SAP R/3 system. BDC works by simulating the user input from transactional screen via an ABAP program.
What are the methods of batch data communication?
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 BDC technique do you prefer?
If we want to transfer large amount of data and when we need to use more than one transaction code we prefer session method. For small or less amount of data and for single transaction use call transaction. (This is more genric answer but you can add more on to this if you have worked on BDC)
How do you explain Lsmw in an interview?
Answer : LSMW is a tool provided by SAP in order to upload huge amount of data from legacy file to R/3 system. The Legacy System Migration Workbench (LSMW) is a tool to transfer data from legacy systems (Non SAP System) into an R/3 System (SAP System).
Why is BDC 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.
What is the difference between call transaction and session method in BDC?
With ‘CALL TRANSACTION USING ‘you can go for update the database both Synchronously and Asynchronously but Sessions method does Synchronous Database updates. During processing, no transaction is started until the previous transaction has been written to the database. Sessions Cannot be generated in Parallel.
What is SAP Lsmw?
The LSMW (Legacy System Migration Workbench) is a tool based on SAP software that supports single or periodic data transfer from non-SAP to SAP systems (and with restriction from SAP to SAP system). Its core functions are: Importing legacy data from PC spreadsheet tables or sequential files.
What is Lsmw in SAP FICO?
How does Lsmw work in SAP?
LSMW is a tool that supports the transfer of data from non-SAP systems (“Legacy Systems”) to SAP R/3 systems. This can be a one-time transfer as well as a periodic one. LSMW also supports conversion of data of the legacy system in a numerous way.
How many steps are there in Lsmw?
14
LSMW supports a step-by-step process; if one step is executed and saved then next step automatically follows. Apart from formation of project/ subproject/ object and recording, there are 14 basic steps included in LSMW.
What is batch input/batch data communication (BDC)?
These two methods are collectively called “batch input” or “batch data communication” ( BDC).Both BDC methods work by carrying out normal SAP transactions, just as a user would. However, BDC can execute the transactions automatically and is therefore suitable for entering large amounts of data that are already available in electronic form.
What is batch input and batch data communication in SAP?
The SAP System offers two primary methods for transferring data into the System from other SAP Systems and non-SAP Systems. These two methods are collectively called “batch input” or “batch data communication” ( BDC).Both BDC methods work by carrying out normal SAP transactions, just as a user would.
What is the use of bit 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.
What are the steps involved in batch input process?
Batch Input Procedures 1 Analysis of the legacy data. 2 Generate SAP data structures for using in export programs. 3 Export the data in to a sequential file. 4 If the SAP supplied BDC programs are not used, code your own batch input program. 5 Process the data and add it to the SAP System. 6 Analyze the process log.
