Is it a panacea of all problems.

Please explain in detail.

Hi,

Batch Data Communication (BDC) is the oldest batch interfacing technique that SAP provided since the early versions of R/3. BDC is not a typical integration tool, in the sense that, it can be only be used for uploading data into R/3 and so it is not bi-directional.

BDC works on the principle of simulating user input for transactional screen, via an ABAP program. Typically the input comes in the form

of a flat file. The ABAP program reads this file and formats the input data screen by screen into an internal table (BDCDATA). The

transaction is then started using this internal table as the input and executed in the background.

In ‘Call Transaction’, the transactions are triggered at the time of processing itself and so the ABAP program must do the error handling. It can also be used for real-time interfaces and custom error handling & logging features. Whereas in Batch Input Sessions, the ABAP program creates a session with all the transactional data, and this session can be viewed, scheduled and processed (using Transaction SM35) at a later time. The latter technique has a built-in error processing mechanism too.

Batch Input (BI) programs still use the classical BDC approach but doesn’t require an ABAP program to be written to format the BDCDATA. The user has to format the data using predefined structures and store it in a flat file. The BI program then reads this and invokes the transaction mentioned in the header record of the file.

BDC may not work smoothly for SAP enjoy transaction. This transaction contains all the information in the information is contained in a single screen with multiple tab pages in it . Where as in previous versions each and every information is contained in a different screen. Therefore when we do BDC its is difficult to handle tabstrips using BDC so we generally follow the old one.

Its not like we can not use BDC for the enjoy transaction. We can but we have to use classes in order to use that.

Hope this will help.

Vishal,

BDC Stands for Batch Data Communication.

It is a very good utility tools. Used of Stress Testing, Master Data Upload.

It is like a Macro, where you records your steps.

While creating BDC, mySAP records the steps being performed by the end-user.

Steps could range from creating master record or passing a transaction.

SCATT, LSMW are other tools that can be used for similar purpose.
