The SAP system offers two primary methods for transferring data into SAP systems. From non-SAP systems or legacy system. These two methods are collectively called batch input or batch data communication.
1. SESSION METHOD
2. CALL TRANSACTION
3. DIRECT INPUT
CALL TRANSACTION
About CALL TRANSACTION
A technique similar to SESSION method, while batch input is a two-step procedure, Call Transaction does both steps online, one after the other. In this method, you call a transaction from your program by
Call transaction <tcode> using <BDCTAB>
Mode <A/N/E>
Update <S/A>
Messages into <MSGTAB>.
Parameter 1 is transaction code.
Parameter 2 is name of BDCTAB table.
Parameter 3 here you are specifying mode in which you execute transaction
A is all screen mode. All the screen of transaction are displayed.
N is no screen mode. No screen is displayed when you execute the transaction.
E is error screen. Only those screens are displayed wherein you have error record.
Parameter 4 here you are specifying update type by which database table is updated.
S is for Synchronous update in which if you change data of one table then all the related Tables gets updated. And sy-subrc is returned i.e., sy-subrc is returned for once and all.
A is for Asynchronous update. When you change data of one table, the sy-subrc is returned. And then updating of other affected tables takes place. So if system fails to update other tables, still sy-subrc returned is 0 (i.e., when first table gets updated).
Parameter 5 when you update database table, operation is either successful or unsuccessful or operation is successful with some warning. These messages are stored in internal table, which you specify along with MESSAGE statement. This internal table should be declared like BDCMSGCOLL, a structure available in ABAP/4. It contains the following fields:
