What’s an ALV field catalog?

In order to display some tabular data in an ALV, the ALV needs some information about the columns/ fields which will be displayed in the ALV. Field catalog is basically the internal table which carries information about each of the columns/ fields with which ALV has to deal with. It need not necessarily contain information about each of the columns/ fields in the data table used as data source of ALV. Only the fields which are important for display or of some technical use for ALV need to be informed to ALV through field catalog.

Difference between CALL TRANSACTION and SESSION Method

Call Transaction method	Classical or session method
In this method, the ABAP/4 program uses the call transaction <T-code > using <bdc_tab> mode <mode> update <update >  method.	In this method, ABAP/4 program read the external data that is to be entered to the SAP system and stores the data in the batch input session. When the prgm has finished creating the session, we can run the session thro the TC SM35. This method involves FM like BDC_OPEN,BDC_INSERT,BDC_CLOSE
In ‘Call Transaction’, the transactions are triggered at the time of processing itself and so the ABAP program must do the error handling.	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.
Synchronous Processing	Asynchronous Processing
We can update the database both synchronously and asynchronously. We can specify the mode in the program.	Synchronous Database update. During processing, no transaction is started until the previous transaction has been written to the database.
No batch input processing log	Detailed Log will be generated for all the sessions
While execution it starts from the first.	While executing it wont start from the first. It will start from the place where it ends with error.
Faster than session method	Not as fast as call transaction method
